Carbide Drill Bit Set for Hardened Steel Stainless Steel Hot Working Steel Metal 1/16 3/16 1/8 1/4 Inch 4 Pcs CNC Tungsten Solid Carbide Twist Drill Bits Set 135° Point Angle
- The Enhanced Tip for Demanding Materials：135° point angle is standard for carbide drills bit machining stainless steel, hot working steel ＜ HRC40 and other high hardness steels. This obtuse geometry strengthens the cutting tip, reduces cutting forces, and minimizes carbide drill bit "slioping or walkino" for improved accuracy and drill life
- Tialsi Coating For Stainless & Hard Steels：TiAlSi coating represents a significant advancement over conventional AlTiN. It features a substantially higher coating hardness of 3,200 HV compared to AlTiN's 2,600 HV, and an elevated oxidation resistance of 1,300°C. This combination, along with its high coefficient of friction, is engineered to withstand the extreme heat and abrasion encountered when drilling stainless steels and high-hardness steel materials
- YFTOOL 4pcs Carbide Drill Bit Set | Precision For Delicate Work：this solid carbide drill bit set includes 1/16", 1/8", 3/16", and 1/4" drills, engineered for fine and precise drilling. the premium carbide construction ensures exceptional rigidity, guaranteeing tight tolerances within ±0.003mm for demanding applications
- Optimized Chip Control & Heat Reduction：the strong pumping effect created by the 30° helix angle can quickly expel long and tough chips out of the hole. this feature, combined with the short chips formed by the 135° point angle, fundamentally solves the problem of chip blockage. smooth chip evacuation removes a large amount of cutting heat, effectively controlling the workpiece temperature, and significantly reducing the work hardening phenomenon common on materials such as stainless steel and hard steel
- 0.4μm K30 Carbide：the foundation of this carbide drill is a k30 grade carbide with an ultra-fine 0.4-micron grain structure. this delivers two key benefits: extreme wear resistance for a longer tool life and superior strength/rigidity to prevent deflection and breakage, ensuring consistent precision in every cut
