Value Collection 01350164 Letter E Hss Screw Machine Drill Bit

Product Description

The VALUE COLLECTION 01350164 is a screw machine length drill bit sized to Letter E (0.2500 inch decimal equivalent), designed for general-purpose drilling in metal, wood, and similar materials. Built from high-speed steel (HSS) with an oxide coating for added lubricity and surface protection, it features a 118-degree standard point angle and a web-thinned, parallel-web construction that reduces thrust and aids penetration. The straight cylindrical shank fits standard drill chucks without modification. With an overall length of 2.5 inches and a flute length of 1.375 inches, this bit is optimized for short-reach applications where rigidity and chip clearance matter. It is sold individually and requires a minimum order of 12 units.

Screw machine length drill bits are used in machining, fabrication, and production drilling environments where a shorter, stiffer bit is preferred over jobber-length alternatives. The reduced length minimizes deflection and improves hole location accuracy, making this bit well suited for drill press work, CNC setups, and hand-held drilling in tight clearances. Right-hand cutting direction and a regular spiral flute pattern make it compatible with standard clockwise-rotating spindles.

Key Features

• Letter E size with 0.2500 inch decimal equivalent for precise sizing
• 118-degree standard point angle for general-purpose material entry
• High-speed steel construction with oxide coating for surface protection and reduced friction
• Web-thinned parallel web reduces drilling thrust and improves chip ejection
• Screw machine (stub) length of 2.5 inches overall for enhanced rigidity and reduced deflection
• Regular spiral flute with right-hand cutting direction for use with standard spindle rotation

Compatibility

Designed as a general-purpose screw machine length drill bit compatible with standard drill chucks and straight-shank collets used in drill presses, lathes, CNC machining centers, and hand-held power drills.

Installation Notes

This bit is installed and serviced by machinists, tool-and-die technicians, maintenance mechanics, and trained fabricators. Ensure the drill chuck or collet is fully tightened and the spindle is at rest before inserting or removing the bit. Select a spindle speed appropriate to the workpiece material and bit diameter following standard machining reference tables. Do not exceed the rated capacity of the holding fixture or apply side-loading force to the shank.
