33/64 Inch Cobalt Drill Bit, M35 HSS Twist Drill Bit, 135° Split Point | Reduced Shank, For metal sheet stainless steel and alloy steel plate drilling 6" length 3" working length

Precision 33/64 inch cobalt drill bit for machining hardened steel and non-ferrous metals. M35 cobalt steel (5% cobalt) provides excellent hardness. Reduced shank and 135 degree split point for accurate drilling

• Contains 5% cobalt in M35 HSS, heat treated to HRC 67 for superior hardness and durability
• 135 degree split point eliminates walking and reduces thrust force, especially on stainless steel
• Cobalt content provides red hardness, allowing faster drilling without bit degradation, Ideal for heavy-duty metal drilling, cast iron, alloy, and non-ferrous materials
• 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
