Value Collection 01397900 Taper Length Drill Bit Hss

Product Description

The VALUE COLLECTION 01397900 is a taper length twist drill bit designed for general-purpose drilling in metal, wood, and similar materials. It measures 0.8071 inches (20.50 mm) in diameter with a 118-degree standard point angle and a black oxide finish that reduces friction and provides light corrosion resistance. The spiral flute geometry, combined with web thinning, promotes efficient chip evacuation and reduces the force required to start and maintain a cut. The straight-cylindrical shank fits standard drill chucks without adapters. This bit is suited for use in stationary drill presses and hand-held power drills operated by machinists, maintenance technicians, and trade professionals.

This taper length drill bit is intended for applications where a longer flute length is needed to reach deeper hole depths than a jobber-length bit allows. With a flute length of approximately 6.73 inches (171.00 mm) and an overall length of approximately 10.28 inches (261 mm), it handles deep-hole work in structural components, fabrication fixtures, and mechanical assemblies. The right-hand cut spiral flute and tapered web configuration make it suitable for general-purpose shop use across HVAC fabrication, plumbing rough-in, and light industrial maintenance tasks.

Key Features

• 0.8071-inch (20.50 mm) diameter with 118-degree standard point angle for general-purpose entry
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Black oxide finish reduces friction and provides basic corrosion resistance
• Web-thinned, tapered web design lowers drilling thrust and improves chip flow
• Right-hand spiral flute with regular spiral type for consistent cutting action
• Straight-cylindrical shank fits standard three-jaw drill chucks directly

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard three-jaw drill chucks on bench drill presses and hand-held power drills that accept straight-cylindrical shanks in this diameter range.

Installation Notes

Secure the straight-cylindrical shank firmly in the chuck and verify runout before beginning a cut. Use appropriate cutting fluid or lubricant when drilling into steel or ferrous metals to extend tool life and improve hole quality. Allow the bit to clear chips frequently on deep passes to prevent heat buildup and flute packing. Wear appropriate PPE including eye protection whenever operating rotary cutting tools.
