Precision Twist Drill 6002069 Jobber Drill Bit No 31

Product Description

The PRECISION TWIST DRILL 6002069 is a solid carbide jobber length drill bit sized at No. 31 (0.1200 inches) with a 118-degree standard point angle. Built from solid carbide throughout, it delivers hardness and wear resistance suited to high-precision drilling in aluminum, non-ferrous metals, and other materials within its rated workpiece range. The bright, uncoated finish leaves the carbide substrate exposed, which works well in applications where coating adhesion or heat buildup is not a concern. With a 2.2500-inch overall length and a 1.2500-inch flute length, this bit fits standard jobber-length chucks and is handled by machinists, tool-and-die tradespeople, and industrial maintenance technicians.

This drill bit is designed for general-purpose drilling operations where tight hole tolerances and a clean entry are required. Its right-hand cut, regular spiral flute geometry and web-thinned tapered web reduce thrust and improve chip evacuation. Primary workpiece materials include aluminum and non-ferrous metals, making it a practical choice for production drilling, fixture work, and maintenance drilling in sheet metal or billet stock. It is sold individually and carries an ANSI standard designation under series D33F-D33W-D33L-D33M.

Key Features

• Solid carbide construction for hardness and dimensional stability in demanding drilling operations
• No. 31 wire gauge size — 0.1200 inches diameter — with straight shank matching the bit diameter
• 118-degree standard point angle with web-thinned, tapered web to reduce entry thrust
• Right-hand cut, regular spiral flute with 1.2500-inch flute length and 10xD flute-to-diameter ratio
• Bright, uncoated finish — no coating buildup to affect critical hole sizing
• ANSI-compliant jobber length format; series D33F-D33W-D33L-D33M

Compatibility

Designed as an OEM-style general-purpose jobber length drill bit for use in standard drill chucks and CNC drilling equipment accepting a 0.1200-inch straight shank. Compatible with aluminum and non-ferrous workpiece materials per the Series D33F-D33W-D33L-D33M specification.

Installation Notes

Install in a compatible drill chuck or collet rated for the 0.1200-inch shank diameter, ensuring the shank is fully seated and the chuck is tightened securely before operation. Ensure the workpiece is clamped or fixtured before drilling to prevent movement and bit deflection. De-energize and lock out any power tool or machine before changing bits. Follow applicable ANSI safety standards and shop-specific PPE requirements when operating carbide tooling.
