- 【Industry Grade M35 Cobalt High Speed Steel】 Made from M35 cobalt steel with 5% cobalt to improve heat resistance and cutting durability during demanding drilling tasks. The material helps maintain edge strength under high temperatures, making it suitable for stainless steel, hardened metal, and other tough materials.
- 【TiAlN Coating】The critical performance differentiator is the TiAlN (Titanium Aluminum Nitride) nano-coating. Increases surface hardness to 89HRC with outstanding heat-resistance, so your drill bit cuts fast and stay sharp. This translates directly to a multi-fold increase in usable life compared to uncoated or standard TiN-coated bits, maintaining a sharp cutting edge through demanding jobs and lowering the long-term cost.
- 【Fully Ground Process & 135° Split Point】 135° Split Point & Twist Design: The 135 degree fast cutting point is automatically centered and penetrates quickly with less pressure, reducing walking. Fully ground spiral groove design clears particles quickly, decreases friction and heat for a faster and cooler drilling performance.
- 【Non-Slip Tri-Flat Shank】 Shank is 5/8" Diameter. 1/2" Triple shank have a tighter grip than round shank and are particularly suited to the machining of hard materials in industry. Flute/Working Length Of This Bit is 3 Inches & The Total Length of the Bit is 6 Inches. Plastic Storage box is Included For Easy Storage.
- 【Engineered for Thin, Hard & Gummy Metals】 Designed for use on stainless steel, hardened metal, aluminum, alloy steel, sheet metal, titanium, cast iron, and more.
