• Carbide-Tipped drill bit is very hard, easy to dissipate heat and can hold an edge longer than other type bits. Similar to the cobalt drill bit, it’s very brittle as well and maybe broken up in improper use. Carbide bits are applicable for drilling fiberglass reinforced plastic and nonferrous heavy metals. - Source: Internet
• Polycrystalline diamond (PCD) is one of the hardest drill bit material, which can be used on the toughest materials, such as glass and ceramic. Actually, diamond tool generally used to grind away material on a micro level, it can last up 20 times as long as a bare tungsten carbide tool, but it also cost much higher than any other options. And diamond bits react negatively when work with ferrous materials like hot steel. - Source: Internet
• Cobalt drill bits are primarily made from a 5–8% cobalt concentration and high-speed steel. This combination improves the heat and wear resistance of the drill bit, making it durable. Cobalt is added to the stainless steel alloy (Iron and Carbon) during formation, enabling resharpening without losing the drill bit’s cutting quality. Cobalt drill bits are best used on tool steel, stainless steel, and other hard ferrous metals. - Source: Internet
• If you determine these two different drill bits in the means of their using purpose, the black oxide drill bit will meet your general-purpose drilling necessity.

• HSS stands for high-speed steel. These durable drill bits are designed to withstand the additional heat from high-speed drilling. Cobalt coated HSS drills offer even more protection. Titanium coated HSS bits are also available, but cobalt is more durable long-term making HSS cobalt drill bits a premium choice. - Source: Internet
• Counterbore drill bits create holes that allow the head of a fastener to sit below the material’s surface. Unlike countersink bits, which create an angled hole for fasteners with angled heads, counterbore drill bits create a larger hole at a shallower depth. A counterbored hole creates a flat ridge on which the head of the fastener can rest. - Source: Internet
• When a metal drill bit containing cobalt is manufactured, it often contains other elements like carbon and titanium for hard surface drilling and black oxide for softer drilling in aluminum and rigid plastics. The surface of the bit is also heat-treated in the manufacturing process, which gives the metal a brownish-gold tint that makes it easy to distinguish from other types of drill bits. Even though cobalt bits are superior in many ways to other types of drill bits, it is still recommended where possible to cool the drilling location with oil while cutting to enhance the life of the drill bit. Since such drill bits are designed to handle high temperatures during the cutting of tough materials, they are rated to withstand prolonged heat of up to 1,100° Fahrenheit (593° Celsius). The ability to withstand such high temperatures without breaking down makes the cobalt drill bit about 30% faster in drilling applications than other types of high strength bits. - Source: Internet
• Like the black oxide drill bit, the titanium drill bit also comes with a 135° split point. It has come with an exclusive titanium nitride coating and unique finish. As a result, it will make sure a high firmness while working through different surfaces. - Source: Internet
• The durability varies depending on the hardness and strength of these two drill bits. In the case of durability, the black oxide drill bit will offer you a 50% longer life span compared to the HSS bits. As a result, you can use this drill bit for years with comfort. - Source: Internet
• Size also affects wear, and length negatively impacts durability. Long drill bits are not as durable as shorter bits due to the amount of torque needed to rotate longer bits. Shorter bits also resist twisting or spinning in the drill chuck better. - Source: Internet
• A cobalt drill bit is a drill bit made for special drilling applications that is composed of steel with a high cobalt content compared to that of other steels, of usually between 5% and 8%. While this makes the drill bit more brittle than traditional steel drill bits, it also makes it much more durable as well as giving it an abrasive quality that helps it to cut through hard materials repeatedly. Ranking cobalt drill bit hardness in comparison to other types of specialized steels puts it above that of high-strength steel (HSS), but below that of titanium steel. Common applications for using a cobalt drill bit include factory settings where a fixed piece of stainless steel or iron needs to be cut repeatedly. The bits work best for linear, controlled cutting of hard materials, and is not ideal for softer materials like wood or plastic because drilling fragments tend to clog up the drilling hole and put angular stress on the bit. - Source: Internet
• Most twist bits come in diameters ranging from 1/16 inch to 1/2 inch, creating holes corresponding with the diameter. Step bits, which are shaped more like a cone, can drill holes ranging in diameter from about 1/8 inch to 1/2 inch, with a maximum depth of 1/4 inch. For deeper holes, look to purchase a twist bit. - Source: Internet
• The History of Twist Drill Bits Twist drill bits were invented as far back as the early 1860s by an American mechanic named Steven Ambrose Morse. Morse’s initial concept was to improve the ease and accuracy of drilling holes by producing a drill bit that began from a sharpened point, with fluting along the sides of the shaft that would help to push the cut material (swarf) back out of and away from the hole as it progressed. To do this, Morse patented an early manufacturing process whereby he would cut two grooves in opposite sides of a cylindrical metal bar, and then twist the bar under heavy torque to produce the now-familiar spiralled or helix double flutes. Although the actual mechanics of production have since been extensively mechanised and streamlined, Morse’s initial twisting method of creating the helical grooves is what gave this style of drill bit its name. - Source: Internet
• Countersink drill bits create shallow holes that allow the head of a fastener to sit flush with the material and are angled to match the tapered head of the fastener. Cobalt countersink bits will create countersink holes in hard metals. Unlike twist drill bits, which include self-piloting tips, countersink bits require an existing hole to drill into a material. To drill countersink holes, twist bits are needed to drill the initial hole, then countersink drill bits are used to create the countersink holes. - Source: Internet
• The drill bit shank is the part that fastens into the drill chuck; the part of the drill that grips and turns the bit. Shanks may be round (also known as “flat”), or shaped for improved grip. Round shanks work well in keyed chucks. In keyless chucks, like those on cordless drills, shaped shanks offer better grip and eliminate the bit slipping inside the chuck. The most popular-shaped drill bit shanks include 3-flat, which have three flat sides ground into an otherwise round shank, and six-sided hex shanks. - Source: Internet
• After drilling the first round of test holes (or after the second round for some harder drill bits), we sharpened the 3/8-inch bits with a bench grinder. We held the cutting edge to the wheel for 5 seconds on each cutting edge, once on the coarse grinding wheel and once on the fine wheel, making sure to maintain the 135-degree original tip angle. To evaluate how well the bits responded to resharpening, we drilled another round of three test holes for each bit in the scrap steel. - Source: Internet
• Compared with carbon steel bits, high-speed steel drill bit is a more popular choice on the market now. HSS is a special type of carbon steel, maintaining structural integrity while bearing high temperature is a marking advantage of the HSS drill bit, what’s more, high speed steel bit has higher wear resistance and hardness, it can also work well at a normal temperature. HSS drill bits are suitable for most of the wood and metal drilling process, including CNC drilling. Titanium nitride and other types of coatings can be applied on the HSS tool to increase lubricity and reduce friction. - Source: Internet
• They are mostly used for cutting through abrasive and hard materials. Cobalt bits have the ability to cut through the hardest of metals, including cast iron, bronze, titanium and stainless steel. They can also easily cut through weld seams. - Source: Internet
• Precision Ground Cobalt drill bits are stronger and harder than Titanium bits but are more brittle and should be handled with care. Cobalt drill bits can drill at much higher temperatures while maintaining sharpness. It can therefore be used to drill stainless steel and other hard materials. - Source: Internet
• One of the chief advantages of cobalt drill bits over many other types of high-strength drill bits is that they do not obtain their hardness through just a surface coating of hardened alloys. Since a cobalt drill bit’s hardness is uniform throughout the entire material, it can be repeatedly sharpened as needed. This is in particular contrast to titanium drill bits, which are better at cutting hard materials than a cobalt drill bit, but the titanium surface of such drill bits cannot be sharpened without destroying the cutting edge. In comparison to HSS drill bits, a cobalt bit can cut on average about 2,200 holes for every 2,000 holes that a HSS drill bit can cut before needing to be sharpened. - Source: Internet
• Cobalt step drill bits are designed to drill holes into sheet metal. With its cone-like shape, a step bit enlarges the hole as it moves through the sheet metal, allowing users to regulate a hole’s diameter. A step bit works with up to 1/4-inch-thick sheet metal. Those looking to drill at shallow depths through sheet metal will want to consider using a step bit. - Source: Internet
• So using black oxide drill bits will unlock your limitation to go through various materials as per your necessity. Titanium drill bit, however, won’t give you that wide range of materials variety. But, you can work with this drill bit through steel, metal, iron, aluminum, magnesium, and also wood. - Source: Internet
• How are Twist Drill Bits Made? Modern manufacturing processes for twist drill bits typically involve clamping a steel bar (or occasionally a different material, in the case of a few specific product types) in a vice or similar assembly, and rotating it at high speed while moving it past a suitably calibrated grinding wheel. During the manufacture of a twist drill bit, the axis of the grinding wheel can be angled to varying degrees, in order to achieve a particular angle of fluting around the shaft of the drill bit. A helical angle of between 28-32 degrees is a universal standard for almost all twist drill bits and is broadly deemed suitable for use on the majority of general-purpose drilling work and materials. However, certain specialised applications or materials can benefit from slightly different fluting angles, and a number of non-standard twist drill bits are manufactured for such purposes. Examples might include: Fast Spiral Twist Bits This type of twist drill bit has a higher helical angle than standard, usually somewhere between 34-38 degrees - Source: Internet
• When you require superior speed and reliance for your drilling project, you require black oxide drill bits for sure. Black oxide is the perfect tool to work through wood, plastic, and even metal. This drill bit has usually a 135° split point that will ensure your fast working mode. - Source: Internet
• Twist bits are general-purpose drill bits and are capable of drilling a variety of different materials. They have angled grooves that spiral around the drill shaft. The edges of these angles are sharp, allowing the bit to burrow into the material. Cobalt twist bits are strong enough to bore into hard metals quickly. They come in a wide variety of sizes, with sets including up to 30 pieces. - Source: Internet
• Reverse Twist Drill Bits Reverse twist drill bits are designed to work with your drill set to the reverse rotation direction (counter-clockwise). However, unlike a standard drill bit which would simply drag its cutting edge backwards around the interior of the hole with the drill running backwards, reverse twist drill bits are machined with their fluted cutting surfaces facing in the opposite direction. When a reverse bit is inserted into a chuck and the drill is run counter-clockwise, this means that the bit performs the same sort of cutting action that a standard drill bit does when moving clockwise. This can be extremely useful as a method of screw extraction when the slots on a screw head have been worn away. - Source: Internet
• In addition, be aware that drilling into hard metal requires a special technique to ensure that the bit cuts into the metal smoothly without overheating. Use a quality drilling lubricant with a high flash point. We used 3-in-1 oil for our tests. Also, drill at a slower speed with moderate downward pressure to avoid damaging expensive bits. The smallest bits can safely drill at about 3,000 rotations per minute (rpm), but larger bits should turn no faster than about 1,000 rpm. - Source: Internet
• As we have seen, both drill bits are made from high-grade materials and perform well. But in terms of strength, solid carbide drill bits are superior, with a hardness of 75 HRC and cobalt’s hardness of 65 HRC on a . The table below compares the pros of cobalt and carbide drill bits. - Source: Internet
• And, its bit size comes with smaller than 1/8 inches. It will help you reduce your friction among the bits and work piece in terms of its added finish. Therefore, these HSS drill bits will speed up your job and help you use your working time more preciously. - Source: Internet
• We tested with an eye out for which drill bits might work especially well for specific metals, such as which ones may be best for stainless steel or best for cast iron. While the unique tips on the Milwaukee 15-piece set proved especially effective at drilling in stainless steel, all of these drill bits would do well boring clean holes into a variety of metals. With that in mind, we assigned awards for each product based more on its features rather than on specific metal uses. - Source: Internet
• Titanium is not only a popular aerospace and medical material, but also a versatile drill bit coating material, which can make the drill bit last longer. Due to its high corrosion resistance, good fatigue limit, heat limit, relatively light weight, and longer service life, titanium coated drill bit is perfect for repetitive mass production of drilling into steel, iron, wood, plastic and various surfaces, it allows a faster RPM and shorter cycle time. The most common types of titanium coatings are Titanium Nitride (TiN), Titanium Aluminum Nitride (TiAN) and Titanium Carbon Nitride (TiCN). TiAN and TiCN are considered superior to TiN as they can increase the lifespan to a considerable degree. The drawback of drill bit coating is that once the tooling becomes blunt, it can’t be sharpened to avoid the coating material being worn away. - Source: Internet
• Long Twist Drill Bits Long twist drill bits are designed for drilling holes which run deeper than a standard-length drill bit. A typical example might include installing security latches on a door, which would require drilling down through the ends of the workpiece to a depth of up to one foot. An especially long twist drill bit will be required to complete everyday tasks such as these, but the main potential disadvantage of an extra-long drill bit is that it can tend to wander more as it goes. Longer twist bits are also more prone to breaking at lower gauges than short bits, particularly when more force is applied to get through greater depths of material. Twist drill bits are also available in a short form. - Source: Internet
• Cobalt drill bits consist of steel with a small percentage of cobalt—the higher the percentage of cobalt, the more heat-resistant and durable the drill bits will be. The amount of cobalt in a drill bit varies. An M35-grade cobalt bit contains 5 percent cobalt, while an M42-grade cobalt bit contains 8 percent. The higher the grade, the more expensive the bit. - Source: Internet
