Value Collection 01391655 Taper Length Drill Bit Hss

Product Description

The VALUE COLLECTION 01391655 is a taper length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. It features a 0.1614-inch (4.10 mm) diameter, a 118-degree standard point angle, and is constructed from high-speed steel (HSS) with a black oxide finish. The black oxide coating reduces friction and provides light corrosion resistance during use. The bit uses a regular spiral flute with a right-hand cutting direction and a tapered web configuration with web thinning to improve chip evacuation and reduce walking at the point. Machinists, pipefitters, and maintenance technicians install this bit in drill presses, hand drills, and machining centers for production and repair work.

This drill bit suits residential and commercial maintenance, light fabrication, and general shop use. The straight-cylindrical shank fits standard drill chucks without adapters. At 119 mm overall length with a 78 mm flute length, it provides additional reach compared to jobber-length bits, making it suitable for drilling in recessed or moderately deep locations where a jobber-length bit would fall short.

Key Features

• 0.1614-inch (4.10 mm) diameter for precise hole sizing
• 118-degree standard point angle for general-purpose use across common materials
• HSS construction provides heat resistance during drilling operations
• Black oxide finish reduces friction and offers light corrosion protection
• Web-thinned tapered web improves chip flow and reduces thrust required at entry
• Straight-cylindrical shank fits standard three-jaw drill chucks

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks accepting a straight-cylindrical shank at 0.1614-inch diameter.

Installation Notes

This bit is installed by machinists and maintenance technicians using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and verify runout before drilling into finished workpieces. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed.
