Value Collection 01397801 Taper Length Drill 0.7874 in Hss

Product Description

The VALUE COLLECTION 01397801 is a taper length twist drill bit designed for general-purpose metal drilling in industrial and trade applications. It measures 0.7874 inches (20 mm) in diameter with an overall length of 10 inches (254 mm) and a flute length of 6.54 inches (166 mm). The bit is manufactured from high-speed steel (HSS) with a black oxide finish that provides light corrosion resistance and reduces friction during cutting. A 118-degree standard point angle makes it suitable for a wide range of common materials including mild steel, aluminum, and similar workpieces. A web-thinned, tapered web design reduces drilling resistance at the point and improves chip clearance.

This drill bit is intended for use in machine shop, maintenance, and fabrication environments where a longer flute length is needed to reach greater drilling depths than standard jobber-length bits allow. The straight-cylindrical shank seats securely in standard drill chucks on bench drill presses, upright mills, and compatible hand-held drilling equipment. Right-hand spiral flutes evacuate chips upward out of the bore during operation. This is a single-piece, general-purpose tool sold individually.

Key Features

• 0.7874 inch (20 mm) diameter with taper length body for extended reach drilling
• 118-degree standard point angle suits a broad range of common workpiece materials
• HSS construction provides durability across general-purpose drilling applications
• Black oxide finish reduces surface friction and offers light corrosion resistance
• Web-thinned, tapered web reduces point thrust and improves chip flow
• Right-hand, regular spiral flute geometry for efficient chip evacuation

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard straight-shank drill chucks on bench presses, drill presses, and milling machines that accept a 0.7874 inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Secure the straight-cylindrical shank fully in the drill chuck before operation and confirm chuck key removal prior to powering the machine. Eye protection and appropriate workholding devices are required when operating drill bits of this diameter. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed selection.
