Built from M35 cobalt high-speed steel (heat treated) and finished with an aluminum titanium nitride (AlTiN) coating, this step bit is engineered for wear resistance and heat performance during demanding jobs. The 1/4" hex shank makes it a convenient fit for many drills and drivers that accept hex-shank bits.
Important use notes: It’s intended for metal sheet up to 1/8" (3 mm) thick and stainless steel sheet up to 1 mm thick. For continuous operation, add cutting oil or use coolant; and expect startup speed may be slower due to the larger cutting angles.
- Triple-flute “C-profile” cutting edge designed for stability, smoother cutting, and faster cutting speed
- M35 cobalt high-speed steel with heat treatment for toughness and bending strength vs. standard HSS
- AlTiN coating (rated 89 HRC per manufacturer) for heat, wear, and corrosion resistance with low friction
- 9 step sizes in one bit: 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4"
- 1/4" hex shank with spiral flute design for versatile drilling in metal, stainless steel, aluminum, and plastic
For shoppers comparing step bits, this EZARC option stands out as a single-piece solution with cobalt steel construction, a wear-focused coating, and clear guidance on recommended material thickness—helpful if you’re drilling sheet goods and want consistent results.
