Value Collection 01390251 Taper Length Drill Bit Hss

Product Description

The VALUE COLLECTION 01390251 is a taper length twist drill bit designed for general-purpose drilling in metal, wood, and similar materials. Built from high-speed steel (HSS) with a black oxide finish, it measures 0.0846 inches (2.15 mm) in diameter and features a 118-degree standard drill point angle. The bit uses a regular spiral flute with a right-hand cutting direction and a straight-cylindrical shank for compatibility with standard drill chucks. Web thinning reduces thrust requirements at the cutting tip, improving penetration efficiency. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this bit.

This drill bit is suited for bench drill presses, CNC drilling machines, and hand-held drill motors where a taper length geometry provides additional reach beyond a jobber-length bit without sacrificing rigidity. The straight-cylindrical shank fits standard three-jaw drill chucks. Its general-purpose grade makes it appropriate for production drilling in mild steel, aluminum, brass, and plastics in light industrial and maintenance environments.

Key Features

• HSS construction provides hardness and heat resistance for metal drilling applications
• Black oxide finish reduces friction at the cutting edge and provides mild corrosion resistance
• 118-degree standard point angle suits a broad range of common work materials
• Web-thinned tip lowers feed force and improves chip clearance at drill entry
• Regular spiral flute with right-hand cut for use in conventional drilling setups
• Straight-cylindrical shank fits standard drill chucks without adapter

Compatibility

Designed as a general-purpose taper length drill bit for use in standard three-jaw chucks on drill presses, CNC machines, and hand-held drilling equipment accepting straight-cylindrical shanks.

Installation Notes

Install and remove drill bits only when the spindle is fully stopped and the machine is powered down or the chuck key is clear of the chuck. Secure the shank fully in the chuck jaws to minimize runout before beginning any cut. Machinists should verify spindle speed against published surface-feet-per-minute recommendations for the workpiece material and drill diameter. Use appropriate cutting fluid or coolant for extended production runs in metal.
