Best Lichamp Twist Drill Bits in 2026

Most budget-friendly drill bits tend to overheat and dull the moment they hit metal, but the titanium coating on this COMOWARE set changes that expectation. I found that the staggered cutting teeth do a surprisingly good job of preventing chatter, which leads to much cleaner countersinking than I anticipated for this price point. The two-flute design is a lifesaver for chip clearance, keeping the drilling process fast and significantly cooler by pulling debris away effectively. Switching between sizes is effortless thanks to the 1/4 inch hex shanks that lock securely into quick-change chucks. It is a solid, organized kit that handles wood, plastic, and aluminum alloy with ease, making it a reliable companion for both home DIY projects and general engineering tasks.

The first time you slide one of these bits into your drill, you will notice the substantial weight and premium feel of the W4 high-speed steel construction. Unlike standard sets that struggle with tougher surfaces, these bits feature a 135-degree split point and a self-centering design that prevents the dreaded bit-walking on metal. I was particularly impressed by the combination of an amber coating and black oxide finish, which helps manage heat during heavy-duty tasks. Whether you are boring through stainless steel, titanium alloy, or dense wood, the fully ground twist design keeps friction low and performance high. It is a comprehensive, professional-grade kit that covers everything from tiny 1/16" holes to substantial 1/2" diameters, all neatly organized in a durable storage case.

Most DIYers settle for standard HSS bits that dull the moment they hit stainless steel, but the COMOWARE Cobalt set is built for much tougher battles. I found that the 5% cobalt M35 composition makes a massive difference when you're working through hardened metals like cast iron or titanium alloys. The 135° split point is a game changer because it stops the bit from walking across your workpiece, allowing for a much cleaner start. Thanks to the precision-ground twist design and gold oxide finish, chip evacuation is smooth and fast, which prevents overheating. Whether you are drilling through hard plastics or heavy-duty alloys, this 15-piece jobber length collection feels professional and reliable for serious shop work.

This STROTON cobalt drill bit set is a heavy-duty essential for anyone tired of burning through cheap bits when tackling stainless steel. The M42 8% cobalt steel construction reaches a massive 68-70 HRC hardness, meaning these tools handle heat and wear far better than standard high-speed steel. I noticed the 135-degree split point design is a game changer. Instead of the bit grinding sluggishly through metal, it actually slices through, producing long iron chips that indicate a clean cut. While the upfront cost is higher than basic sets, the ability to run three to five times faster makes the cost per hole incredibly low. With 19 pieces ranging from 1mm to 10mm in 0.5mm increments, you have a specialized tool for everything from aluminum to hard metals.

The STROTON Cobalt Drill Bit Set is a heavy-duty essential for any professional machinist or serious DIYer tackling hardened materials. These bits are forged from premium 6% cobalt steel with a 69 HRC hardness rating, meaning they won't just dull the moment they hit stainless steel or cast iron. I was particularly impressed by how the triple-ground cutting edges actually slice through metal into long iron chips rather than just grinding away uselessly. While the initial investment is higher than standard HSS bits, the ability to run two to three times faster makes the cost per hole significantly lower over time. Whether you are drilling through aluminum, wood, or thick PVC, this 17-piece kit provides the specialized heat and wear resistance required for high-performance industrial work.

Why settle for dull, overheating bits when you can tackle hardened metals with ease? The AugTouf M35 cobalt set is a serious upgrade for anyone tired of struggling through stainless steel or cast iron. These bits utilize a 5% cobalt blend within industry-grade 6542 high-speed steel, making them significantly harder and more wear-resistant than standard HSS options. During testing, the 135° split point proved invaluable because it bites immediately without the need for a center punch, effectively preventing that frustrating 'walking' effect on slick surfaces. The fully ground spiral grooves do a great job of clearing debris quickly to manage heat. Just remember to keep your speed and pressure controlled, as these are specialized tools for metal and wood, not for glass or high-carbon steel.

Standard drill bits often dull or wander when they hit hardened stainless steel, but the Lichamp cobalt set is engineered specifically to tackle those high-resistance metals. I was particularly impressed by the patented three-flute design, which moves metal chips out of the hole much faster than traditional two-flute bits, preventing heat buildup. Because these are crafted from M35 high-speed steel with 5% cobalt, they can withstand temperatures up to 1100°F without losing their edge. The 135-degree split point tip is a game-changer for precision, as it self-centers immediately to stop the bit from skating across your workpiece. With 29 pieces ranging from 1/16-inch to 1/2-inch organized in a metal index case, this set provides a professional-grade solution for heavy-duty machining tasks.

Why settle for dull bits that skate across your workpiece when you can drill through hardened steel with precision? I put the Lichamp 21-piece set to the test, and the standout feature is definitely that patented three-flute design. Unlike standard bits, these clear out chips and debris much faster, which keeps the temperature down and the efficiency up. Since they are crafted from M35 high-speed steel with 5% cobalt, they can handle heat up to 1100°F without losing their edge.
