1 Inch Cobalt Drill Bit (1 Inch)

Key Features

• M35 high speed steel with 5% cobalt, heat treated to HRC 67 for maximum edge retention and heat resistance
• Reduced shank (6" total, 3" working length) allows use of 9/16 inch bit in standard drill chucks
• 135 degree split point provides instant penetration without center punching, Cobalt alloy maintains cutting edge at high temperatures, ideal for drilling cast iron and stainless
• 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
