Value Collection 01392851 Taper Length Hss Drill Bit

Product Description

The VALUE COLLECTION 01392851 is a taper length twist drill bit designed for general-purpose metal drilling in production and maintenance environments. Ground from high-speed steel (HSS) with a black oxide finish, this bit provides added lubricity and corrosion resistance compared to bright-finish alternatives. The 118-degree standard point angle suits a wide range of ferrous and non-ferrous materials. At 0.2559 inches (6.50mm) in diameter, it fills a common sizing need between fractional and metric drill sets. The web-thinned, tapered web construction reduces thrust force at the cutting point, improving chip evacuation and extending service life under repeated use. Licensed trades and maintenance machinists rely on this type of bit for through-hole and step-drilling operations.

This drill bit is suited for use in hand-held drill presses, benchtop drill presses, and CNC or manual machine tool setups where a straight cylindrical shank is accepted. The taper length body provides additional reach beyond a jobber-length bit without sacrificing rigidity, making it useful for deeper hole applications in structural components, brackets, and mechanical assemblies. The right-hand spiral flute configuration is standard for conventional drilling operations. Sold individually, it is appropriate for single-use replacement or as a stock addition to a shop or field tool kit.

Key Features

• 0.2559 inch (6.50mm) diameter with taper length body for extended reach
• 118-degree standard point angle for versatile use across ferrous and non-ferrous materials
• High-speed steel (HSS) construction for durability under repeated drilling cycles
• Black oxide coating adds lubricity and mild corrosion resistance
• Web-thinned, tapered web reduces thrust and improves chip clearance
• Straight cylindrical shank fits standard drill chucks without adapters
• Right-hand cut spiral flute for conventional forward-direction drilling

Compatibility

Designed as a general-purpose taper length drill bit compatible with any drill press, hand drill, or machine tool equipped with a straight-shank chuck sized to accept a 0.2559 inch diameter shank.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Use cutting fluid or lubricant when drilling steel or cast iron to preserve cutting edge life. Allow the bit to cool between deep-hole passes to avoid heat buildup that can soften the HSS cutting edges. Worn or chipped bits should be replaced rather than reused in precision applications.
