Value Collection 01400258 Taper Length Drill 25/64 Hss

Product Description

The VALUE COLLECTION 01400258 is a taper length drill bit designed for general-purpose metal drilling applications. Built from high-speed steel (HSS) with a black oxide finish, this bit offers improved lubricity and moderate corrosion resistance compared to uncoated HSS. The 118-degree standard point angle suits a wide range of common materials including mild steel, aluminum, and plastics. The web-thinned, tapered web configuration reduces thrust at the point and improves chip evacuation. At 0.3906 inches (25/64 inch) in diameter with a 7-inch overall length, this bit is suited for applications requiring extra reach beyond what a jobber-length drill provides. Installation is performed by machinists and metalworking tradespeople.

This taper length drill bit is used in general machining, fabrication, and maintenance repair operations where a longer flute and extended reach are required. The 4.375-inch flute length allows drilling deeper holes without repositioning. The straight-cylindrical shank is compatible with standard three-jaw drill chucks on drill presses, hand drills, and milling machines. Right-hand cutting direction is standard for conventional clockwise-rotating spindles. The regular spiral flute promotes consistent chip removal during through-hole and deep drilling operations in a shop or field setting.

Key Features

• 118-degree standard point angle for general-purpose drilling in metal, aluminum, and plastics
• Web-thinned tapered web reduces drilling thrust and improves point entry
• 4.375-inch flute length provides extended reach for deeper hole applications
• Right-hand spiral flute promotes efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose taper length drill bit compatible with any standard drill chuck or collet system accepting a straight-cylindrical shank at 0.3906 inches (25/64 inch) diameter, including drill presses, CNC machining centers, and hand-held power drills.

Installation Notes

Install in a clean, properly sized drill chuck and tighten securely before operation. Power down and lock out the machine before changing bits. Use appropriate cutting fluid for the material being drilled to extend tool life and maintain hole quality. Verify spindle runout before use in precision applications.
