Product Details
✓【M35 Cobalt HSS】Built with industrial-grade M35 cobalt HSS and precision heat treatment, this step drill bit stays sharp under high heat and heavy-duty use. Stronger and more durable than ordinary HSS drill bits, it easily handles stainless steel, metal sheets, aluminum, and other hard materials while reducing wobble and breakage.
✓【Triple-Flute Design】EZARC step drill bits feature an advanced triple-flute structure for improved drilling stability and reduced walking during operation. The precision-engineered C-profile cutting edge delivers faster chip removal, smoother cutting performance, and cleaner.
✓【AlTiN Coating】AlTiN coating with up to 89HRC hardness, these step drill bits offer exceptional thermal stability, wear resistance, and corrosion protection. The low-friction surface enhances cutting efficiency and extends tool life during repeated drilling applications.
✓【13 Step Sizes】Spiral flute design, featuring nine distinct steps, offers seamless and effective drilling across various thicknesses, eliminating the need for multiple bits. Includes 1/8",5/32", 3/16", 7/32", 1/4", 9/32", 5/16", 11/32", 3/8", 13/32", 7/16",15/32",1/2"
✓【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
