Value Collection 01397405 Taper Length Drill Bit Hss

Product Description

The VALUE COLLECTION 01397405 is a taper length drill bit designed for general-purpose metal drilling in professional shop and field environments. Ground from high-speed steel (HSS) with a black oxide finish, it measures 0.7087 inches (18mm) in diameter and features a 118-degree standard point angle. The web-thinned, tapered web configuration reduces thrust at the point and helps center the drill on entry. A straight-cylindrical shank seats securely in standard drill chucks. Machinists, tool-and-die technicians, and maintenance mechanics reach for taper length drills when extra flute length is needed to clear chips in deeper bores without stepping up to a longer extended series bit.

This drill bit is suited for general-purpose applications in mild steel, cast iron, aluminum, and similar materials where a 0.7087-inch diameter through-hole or blind bore is required. The taper length body provides more reach than a jobber bit while remaining more rigid than a long series drill, making it a practical choice for structural fabrication, maintenance repair, and machine-shop work. Right-hand spiral flutes evacuate chips efficiently during through-hole drilling operations.

Key Features

• 0.7087 inch (18mm) diameter for precise sizing in imperial and metric applications
• HSS construction provides hardness and wear resistance for repeated use in ferrous and non-ferrous metals
• Black oxide finish reduces friction and provides light corrosion resistance during storage
• 118-degree standard point angle suitable for general-purpose drilling in a wide range of materials
• Web-thinned tapered web lowers cutting thrust and improves self-centering on the workpiece
• Right-hand regular spiral flutes promote consistent chip evacuation
• Straight-cylindrical shank fits standard three-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks accepting a straight-cylindrical shank at 0.7087 inches diameter.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with drill press, lathe, or handheld power tool operation. Secure the shank fully in the chuck and confirm runout is within acceptable limits before beginning a cut. Always use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Wear ANSI-rated eye protection and secure the workpiece firmly before drilling.
