  • Provides much cleaner and smoother hole cutting compared to standard step bits. M2 contains 50% more tungsten and 150% more molybdenum, which are critical for improved durability. Our advanced vacuum heat treatment and Nitride surface hardening process further enhance its overall performance.
  • With polished steps and clearly highlighted size indicators, you can effortlessly view the desired hole size while drilling, eliminating the need to stop midway. This ensures a faster and more efficient drilling experience.
  • Leveraging precise CNC machining and years of refined design, our bit offers effortless, fast, and precise cuts, outperforming typical step bits on the market.
  • Designed to cut through a variety of materials, including stainless steel (with proper pressure), hardened steel, mild steel, galvanized steel, aluminum, copper, plastic, and wood. It can handle stainless steel up to 12 gauge (2.7mm) thickness.
