Precision Twist Drill 6001115 Taper Shank Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6001115 is a taper shank drill bit engineered for general-purpose metal drilling in production and maintenance environments. Built from high speed steel with an oxide finish, it delivers consistent performance in a wide range of ferrous and non-ferrous materials. The bit measures 27/32 inch (0.8438 inches) in diameter, runs 10.75 inches overall, and features a standard 118-degree point angle with a web-thinned tip to reduce thrust and improve chip ejection. Licensed machinists, toolroom technicians, and industrial maintenance mechanics are the primary users of this bit type.

This drill bit is suited for use in drill presses, lathes, and machining centers equipped with a Morse taper spindle. The 3MT shank seats directly into a matching taper socket, eliminating the need for a separate chuck on machines configured for taper-drive tooling. The spiral flute design with a 4xD flute-to-diameter ratio handles moderate-depth holes in steel, cast iron, aluminum, and similar materials. It conforms to ANSI standards and is classified as a Series 209 general-purpose tool.

• 118-degree standard point angle with web-thinned tip for reduced entry thrust
• High speed steel construction with oxide finish for corrosion resistance
• 6.125-inch spiral flute length supports chip clearance in moderate-depth bores
• Meets ANSI standards; Series 209 general-purpose classification

Compatibility

Designed for use in drill presses, lathes, and machining centers equipped with a No. 3 Morse Taper spindle socket or sleeve adapter.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom technicians familiar with taper-drive tooling. Before seating the shank, clean and inspect the taper bore and shank surfaces for burrs, chips, or debris that could cause misalignment or runout. Power down and lock out the machine before inserting or removing the bit. Use a proper drift key and a soft-faced mallet to eject the bit from the taper socket — never use the quill feed mechanism to force removal.
