12pcs 3/16" Cobalt Drill Bits, M35 High Speed Steel 135 Degree Tip Heavy Duty Jobber Metal Drill Bits Set for Hardened Metal Stainless Steel Cast Iron Wood Plastic
- Cost-effective combination: One set contains a total of 12 3/16" cobalt drill bits, with an average price per bit lower than the market average price.
- Material composition and characteristics:Our cobalt drill bits are made of M35 material, which gives it excellent wear resistance and high-temperature hardness. This material maintains toughness and strength at high temperatures, and it is suitable for high-speed cutting and drilling of complex materials. The heat treatment can achieve high hardness (HRC65.5-68), so the drill bit can still maintain high hardness and wear resistance at high temperatures.
- Cutting performance:M35 cobalt drill bits perform well when cutting harder metals (such as stainless steel, alloy steel, etc.) and can maintain a long service life. The cutting edge is precisely ground, which makes the drill bit cut smoothly and reduces heat generation during the cutting process. With the 135-degree split point tip design, jobber drills can better self-center, reduce sliding, improve the cutting efficiency , and reduce the risk of wear and breakage.
- Application range:This M35 cobalt drill bit set is suitable for a wide range of industrial applications, compatible with any standard drill.In addition to home DIY, it can be used in fields such as automobiles, aerospace and mold manufacturing, especially in occasions where hard materials need to be processed or high-precision drilling is required.
