Product Details
✓【M35 HSS】M35 cobalt high-speed steel, through heat treatment, achieves toughness and bending strength that surpass standard high-speed steel, making this step drill bit more suitable for cutting hard materials
✓【C-Profile Design】EZARC step drill bits feature a triple-flute design for increased stability, effectively reducing deviation during the cutting process. Additionally, the C-profile cutting edge ensures smoother cutting and an increased cutting speed
✓【AlTiN Coating】Step bits coated with aluminum titanium nitride, rated at 89HRC for exceptional hardness and thermal properties. This coating offers superior resistance to heat, wear, and corrosion, with high adhesion and low friction
✓【19 Step Sizes】Spiral flute design, featuring nineteen distinct steps, offers seamless and effective drilling across various thicknesses, eliminating the need for multiple bits. Includes from 1/4" - 1- 3/8"
✓【Please Note】Material thickness: Suitable 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 coolant before use. Due to the larger cutting angles, the startup speed may be slower
