Titan Usa CD40031 Jobber Drill Bit 31/64 Inch Hss

Product Description

The TITAN USA CD40031 is a high speed steel jobber-length drill bit designed for production and maintenance drilling in metal fabrication and machining environments. It measures 31/64 inch (0.4844 inch) in diameter with a 5-7/8 inch overall length and a standard 118-degree split point. The black oxide coating reduces friction and provides light corrosion resistance during use. Two spiral flutes with a regular helix evacuate chips efficiently, and the straight cylindrical shank seats cleanly in standard drill chucks. Licensed machinists, tool-and-die techs, HVAC fabricators, pipefitters, and general maintenance mechanics rely on this geometry for consistent hole quality in ferrous and non-ferrous stock.

The CD40031 is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The 9xD flute-to-diameter ratio gives it the reach needed for most jobber-length applications without sacrificing rigidity. It is appropriate for use in bench drill presses, hand drills, and CNC drilling operations where a straight-shank, fractional-size bit is required. The 4-3/8 inch flute length supports a maximum drilling depth of 4-3/8 inch per pass.

Key Features

• 31/64 inch diameter with a tight tolerance of -0.0010 to +0.0000 inch for consistent hole sizing
• 118-degree standard point angle suited to a wide range of metal drilling applications
• Black oxide finish reduces friction and light surface oxidation during drilling
• High speed steel construction withstands heat generated in ferrous and hard-alloy drilling
• Right-hand spiral flute with regular helix for effective chip evacuation
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed for use in standard drill chucks accepting straight cylindrical shanks up to 31/64 inch diameter. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium (UNSPSC material codes P, M, K, N, S).

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling. Use cutting fluid appropriate to the workpiece material to extend tool life and improve hole finish, particularly in stainless steel and superalloys. Reduce feed pressure as the point breaks through to prevent workpiece burring and bit deflection. Inspect flutes for clogging or chipping before each use and replace the bit if cutting edge damage is present.
