Cleveland C70001 Cobalt Drill Bit 1/32 Inch 135 Degree

Product Description

The CLEVELAND C70001 is a jobber-length drill bit designed for precise, small-diameter drilling in metalworking and fabrication applications. Built from M42 cobalt high-speed steel with a gold oxide coating, this bit delivers elevated heat resistance and extended tool life compared to standard HSS tooling. The 135-degree split point reduces walking and allows the bit to engage material without a center punch in most setups. With a 1/32 inch diameter, a flute length of 0.5 inches, and an overall length of 1-3/8 inches, this is a compact, heavy-duty bit suited to tight-tolerance work. The straight-cylindrical shank fits standard drill chucks without adapters.

This bit is rated as a primary workpiece material match for aluminum, though M42 cobalt construction also handles stainless steel, cast iron, and other hard or abrasive materials commonly encountered in trade and industrial environments. The Series 2213 designation meets NAS 907 Type J specification, making it appropriate for aerospace-adjacent and precision manufacturing work. HVAC fabricators, pipefitters, electricians, and sheet metal workers will find this bit useful for pilot holes, panel penetrations, and small-bore work on metal substrates.

Key Features

• M42 cobalt steel construction for high heat tolerance and durability in hard materials
• 135-degree split point reduces bit walking and improves entry accuracy
• Gold oxide coating improves lubricity and surface hardness for extended bit life
• Web-thinned, tapered web design reduces cutting torque and chip packing
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Meets NAS 907 Type J specification for precision and aerospace-grade applications

Compatibility

Designed as a jobber-length replacement or stock bit for standard straight-shank drill chucks accepting 1/32 inch diameter tooling. Primary workpiece material is aluminum; M42 cobalt grade is also suited to stainless steel, cast iron, and other hard metals.

Installation Notes

Installation is performed by machinists, fabricators, and trade technicians using a standard drill press, hand drill, or driver with a compatible chuck. Secure the straight-cylindrical shank fully in the chuck before operation and verify chuck key is removed before powering the tool. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and maintain dimensional accuracy. At 1/32 inch diameter, apply light, consistent feed pressure to avoid bit deflection or breakage.
