37 64 Inch Cobalt Drill Bit (37/64 Inch)

Key Features

• Professional M35 Cobalt Alloy – Made of 5% cobalt HSS with heat treatment, hardness up to HRC 67. Ideal for drilling stainless steel, cast iron, hardened metal, copper, and non-ferrous alloys
• Superior Heat Resistance & Long Life – Provides stable performance in high-temperature applications. Delivers up to 5x longer life compared to standard HSS bits
• Precise Hole with Split Point – 135° split point tip reduces walking and allows immediate contact. Straight round shank ensures better concentricity for accurate drilling results
• Efficient Chip Removal – Tapered web helix design adds stability in tough materials. Large spiral flute quickly removes metal chips, enabling faster drilling speed
• Ultrasonically welded outer shell creates a permanent seal; any opening attempt leaves irreversible traces, ensuring brand-new products. The inner storage case prevents metal-on-metal friction during transit, protecting cutting edges and coating, and serves as permanent organizer by size. This dual design combines tamper-evident security with a reusable case that lasts the drill bits' entire life
