- Nano TiAlN Coating: Advanced nano-structured TiAlN coating delivers longer tool life than standard TiN coatings, enables higher drilling speeds, and provides heat resistance up to 1500 °F. This coating offers outstanding wear resistance, corrosion resistance, strong adhesion, and reduced friction.
- Premium M35 Cobalt HSS: Made from high-quality M35 high-speed steel with approximately 5% cobalt, enabling efficient drilling across a wide range of materials, including stainless steel up to 3 mm thick and iron, aluminium, and other metals up to 5 mm thick. Optimized step drill design with a deep double-helix flute for faster chip removal.
- 18-Step Size Range (3/16"–1-1/4"): This M35 HSS step drill bit features 18 precision steps, including 3/16”, 1/4”, 5/16”, 3/8”, 7/16”, 1/2”, 9/16”, 5/8”, 11/16”, 3/4”, 13/16”, 7/8”, 15/16”, 1”, 1-1/16”, 1-1/8”, 1-3/16”, and 1-1/4”. Ideal for drilling, enlarging, deburring, and general daily drilling tasks.
- 3/8" Tri-Flatted Shank: The 3/8" tri-flat shank provides a secure grip and reduces slippage, ensuring stable performance in cordless drills, drill drivers, and bench drills.
- Helpful Tips: Use cutting oil or lubricant during drilling to reduce friction and heat buildup, especially when working with metal. As step drill bits are wear items, regular inspection and timely replacement are recommended under heavy use.
