Value Collection 01350297 Screw Machine Drill Bit 29/64

Product Description

The VALUE COLLECTION 01350297 is a screw machine length drill bit designed for general-purpose drilling in metal, wood, and plastic. The shortened overall length of 3.5625 inches compared to a jobber-length bit provides greater rigidity and reduced deflection in drill press, lathe, and CNC applications. The 29/64 inch diameter (0.4531 inch decimal) cutting edge is ground to a 118-degree standard point angle with web thinning for easier penetration and reduced thrust. The high-speed steel construction with oxide coating provides basic lubricity and light corrosion resistance during normal shop use. This bit is suited for machinists, maintenance technicians, and fabricators working in production or repair environments.

This drill bit is well suited for use in drill presses, milling machines, lathes, and other fixed machine tool setups where a shorter, stiffer bit reduces chatter and breakage. The straight cylindrical shank fits standard three-jaw chucks and collet holders. Its general-purpose grade makes it appropriate for moderate-volume production drilling in ferrous and non-ferrous materials at conventional cutting speeds.

Key Features

• 29/64 inch diameter with 0.4531 inch decimal equivalent for precision sizing
• 118-degree standard point angle with web-thinned tip for reduced entry thrust
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Oxide coating provides basic lubricity and light surface protection
• Screw machine length overall length of 3.5625 inches for added rigidity and reduced deflection
• Right-hand cutting with regular spiral flute and 2.125 inch flute length for efficient chip evacuation

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard three-jaw chucks and collet holders accepting straight cylindrical shanks in the 0.4500 to 0.5000 inch diameter range.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard machine tool chuck or collet setups. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Secure the shank fully in the chuck or collet to the appropriate depth before applying cutting load. Do not exceed the recommended cutting speed for the material being drilled, and use cutting fluid where appropriate for longer tool life.
