Product Details
✓【Long-Lasting Durability】EZARC step drill bit is made from heat-treated M35 cobalt high speed steel for superior strength and toughness over standard HSS, making it ideal for cutting stainless steel and other hard metals. The 89HRC AlTiN coating provides excellent heat, wear, and corrosion resistance for extended tool life.
✓【Triple-Flute C-Profile Design】Triple-flute structure improves drilling stability and reduces walking. The C-profile cutting edge enables faster, smoother cutting and cleaner holes in metal, stainless steel, aluminum, and plastic.
✓【12-Step Sizes】Spiral flute design enables smooth, efficient drilling across multiple material thicknesses, eliminating the need to change bits. Includes 12 sizes: 3/16", 1/4", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8".
✓【Reinforced Shank】The 5/16'' thickened shank increases strength, fits perfectly into 1/4" quick-change chucks, is designed for quick-change drills and impact drivers, and can extend drilling depth to meet deep-hole requirements.
✓【Important Notes】Suitable for metal sheets up to 1/8" (3mm) thick and stainless steel up to 1mm. For better performance and longer tool life, add cutting oil or coolant before continuous drilling.Due to the larger cutting angles, initial drilling speed may be slower, which is normal.
