High Hardness Spiral Groove Step Drill Bit Set, Industrial Grade Step Drill Bit Set, Durable Heavy Duty Spiral Groove Drill Bit Set, Suitable for Stainless Steel, Aluminum and Plastic
- Slash your tool inventory with 3 split drill bits that replace 29 standard bits. Each 1mm incremental step (4–32mm range) handles precise hole sizing without swapping tools, ideal for steel beams, pipes, and sheet metal.
- Tungsten-carbide coating maintains razor sharpness through 5x more cycles than standard bits. The spiral design distributes heat evenly, preventing warping even at 1,500 RPM in stainless steel.
- Optimized helical grooves reduce cutting resistance by 40% vs. 2-flute designs. Continuous spiral channels eject debris instantly, eliminating clogging during deep drilling in copper or aluminum.
- 30% thicker hexagonal shanks resist torsional stress during high-torque drilling. Compatible with bench drills (3/8"–1/2" chucks) and impact wrenches up to 650 lb-in torque.
- Laser-hardened cutting edges chew through hardened steel (HRC 45+), cast iron, and aerospace-grade aluminum without chipping. Includes diameter markings for quick size verification mid-task.
