• 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
• Counterbore drill bits create holes that allow the head of a fastener to sit below the material’s surface.

The shank comes in a round shape and prevents wear and tear during work. And the flat sides provide an excellent grip when coming in contact with the chuck. - Source: Internet
• Before you start drilling, put a few drops of oil on the metal to lubricate the drill bit and reduce the amount of heat produced during drilling, which lessens the chance of dulling the drill bit. For this reason, you’ll also want to drill slowly to prevent overheating. Put a block of wood under the metal, so when the drill bit penetrates the steel, it won’t get dulled by whatever other surface else you’re working on. - 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
• What makes this item unputdownable is its superior performance delivery. It is built to last, and it is made of cobalt and M42 alloy, which increases the lifespan by 10 percent. As a result, it has a high heat resistance and can cut through the hardest materials. Be it aluminum, titanium, or cast-iron; this can manage to work through them all. - Source: Internet
• We were not impressed with the quality of the storage case that is included in the package. It is made of flimsy plastic and breaks off within a few uses. We suggest that you buy a sturdier case to store the drill bits safely. - Source: Internet
• When a product is made of M35 grade alloy, there’s no doubt that it will be durable. The HSS cobalt helps enhance the strength of the drilling bits comparatively, and they last a lot longer than most of their contemporaries. It also adds to its heat-resistant capacity and does not get damaged even during extreme climates. - 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
• If you’ve already drilled a hole and you want to make it larger, fold a small piece of emery cloth in half, with the abrasive side facing inward, and put it over the hole. The advantages to drilling this way is that you’ll be cutting down on the noise level while you work; in addition, you won’t get a jagged hole. Drill right through the emery cloth with the wider drill bit, and you’ll see a nice, smooth hole. - 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
• 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 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
• 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
• TiCN (titanium carbonitride, blue-gray color) Great for stainless steel, cast iron and aluminum. Harder and more wear-resistant than other coatings. TiALN (titanium aluminum nitride, violet color) For use in high-alloy carbon steels, nickel-based materials and titanium. Not used for aluminum. - Source: Internet
• If a shorter drill bit can do the job, it’s a good option. Shorter drill bits are more accurate and because they’re more rigid they don’t break as often. This helps keep workers on task and the project on schedule. Shorter drill bits are also better in tighter, more confined areas. - Source: Internet
