Value Collection 01350255 Screw Machine Drill Bit 25/64 in

Product Description

The VALUE COLLECTION 01350255 is a screw machine length drill bit designed for high-throughput drilling in metal, wood, and general-purpose materials. Built from high-speed steel (HSS) with an oxide coating for added surface protection, this bit features a 118-degree standard point angle and a web-thinned tip that reduces thrust and improves centering on entry. At 25/64 inch (0.3906 inch) in diameter with a 3.25-inch overall length and a 1.875-inch flute length, it fits standard drill chucks and screw machine applications where a shorter, stiffer bit is preferred over jobber-length alternatives. Machinists, maintenance techs, and trade professionals install this bit in drill presses, lathes, and handheld drills.

This bit is suited for general-purpose drilling in production and shop environments. Its shorter overall length relative to jobber-length bits reduces deflection and improves hole accuracy in CNC setups, turret lathes, and manual drill presses. The straight cylindrical shank seats securely in standard three-jaw chucks. Applications include drilling through steel plate, structural members, pipe, and similar materials encountered in HVAC, plumbing, and electrical rough-in work where a stubby, rigid bit is needed for close-quarter or fixture-mounted drilling.

Key Features

• 25/64 inch (0.3906 inch) diameter for precise hole sizing within the 0.3500 to 0.4000 inch range
• 118-degree standard point angle with web-thinned tip reduces entry thrust and improves self-centering
• High-speed steel construction handles the heat generated in continuous or production drilling
• Oxide coating provides surface protection and mild lubricity during cutting
• Screw machine length at 3.25 inches OAL delivers added rigidity and reduced deflection versus jobber bits
• Right-hand, regular spiral flute with parallel web configuration for reliable chip evacuation

Compatibility

Designed as a general-purpose replacement or stock bit compatible with standard straight-shank drill chucks used in drill presses, screw machines, turret lathes, and handheld power drills.

Installation Notes

A licensed machinist or qualified trade professional should secure the straight shank fully in the chuck before operation, ensuring no runout that could cause breakage or oversize holes. Always wear eye protection and secure the workpiece before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Do not exceed the recommended feed and speed ratings for the workpiece material and machine type.
