Titan Usa CD30301 Drill Bit Letter a Hss Black Oxide

Product Description

The TITAN USA CD30301 is a screw machine length drill bit sized to Letter A (0.2340 inches, equivalent to 15/64 inches) with a 135-degree split point and a high-speed steel construction finished in black oxide. Screw machine length bits are shorter than jobber-length bits, providing increased rigidity and reduced deflection in tight workspaces or drill press applications. The split point geometry reduces walking at startup, eliminating the need for a center punch on most materials. Black oxide coating provides mild lubricity and corrosion resistance. This bit is suited for metalworking, mechanical, and maintenance trades requiring precise, repeatable hole sizing.

The CD30301 is used in general metalworking, machine shops, maintenance and repair operations, and production drilling where a short, stiff bit is preferred. Its Letter A diameter is commonly specified for tapping and close-tolerance hole applications in steel, cast iron, aluminum, and similar materials. The straight cylindrical shank accepts standard drill chucks. This bit is typically installed by machinists, millwrights, pipefitters, and maintenance mechanics working on ferrous and non-ferrous metals.

Key Features

• Letter A size: 0.2340 inches decimal equivalent, matching 15/64 inches nominal
• 135-degree split point reduces bit walking and eliminates center punch in most applications
• Screw machine (stub) length at 2-7/16 inches OAL increases rigidity over jobber-length bits
• High-speed steel construction rated for heavy-duty drilling in metal
• Black oxide finish provides mild corrosion resistance and lubricity
• 2-flute spiral design with 1-5/16 inches flute length for efficient chip evacuation

Compatibility

Designed as an OEM-style replacement or direct-use screw machine drill bit for standard drill chucks and drill presses accepting straight cylindrical shanks in the Letter A size range (0.2000 to 0.2500 inches).

Installation Notes

This bit is installed by machinists and maintenance trades using standard drill chucks on drill presses, CNC machines, or hand drills. Ensure the chuck is fully tightened around the straight cylindrical shank before operation. Always power down and isolate the machine before changing bits. Use appropriate cutting fluid for steel and ferrous metals to extend bit life and improve hole quality.
