Precision Twist Drill 6001039 Taper Shank Drill Bit 3MT

Product Description

The PRECISION TWIST DRILL 6001039 is a taper shank drill bit engineered for general-purpose metal drilling in professional shop and industrial environments. Built from high speed steel with an oxide finish, it delivers reliable performance in ferrous and non-ferrous materials. The bit measures 0.9219 inches (59/64 inch) in diameter with a 118-degree standard point and a web-thinned tip geometry that reduces thrust and improves centering. Overall length is 10.75 inches with a 6.125-inch spiral flute. The 3MT (Morse Taper 3) shank seats directly into compatible drill press and lathe spindles without a chuck. This bit meets ANSI standards and is sold individually.

This drill bit is suited for machine shop production drilling, maintenance and repair operations, and toolroom work where a rigid taper-shank interface is required. The Series 209 design targets general-purpose right-hand cutting applications in drill presses, lathes, and milling machine setups. The 4xD flute-to-diameter ratio provides sufficient chip clearance for moderate-depth holes. It is a working-grade tool for machinists and tool and die technicians who need consistent results across a range of steels, cast iron, aluminum, and similar materials.

Key Features

• 0.9219-inch (59/64 inch) diameter high speed steel construction for broad material compatibility
• 3MT Morse Taper shank for direct spindle mounting without a chuck adapter
• 118-degree standard point with web-thinned tip for reduced thrust and improved self-centering
• Oxide finish for basic lubricity and corrosion resistance during storage and use
• Regular spiral flute, right-hand cutting direction, 6.125-inch flute length for effective chip evacuation
• Meets ANSI standards; Series 209 general-purpose classification

Compatibility

Designed for use in drill press spindles, lathes, and milling machines equipped with a Morse Taper 3 (3MT) socket. No chuck or adapter is required when the machine spindle accepts a 3MT taper directly.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before seating or removing the taper shank. Clean both the shank taper and the spindle socket thoroughly before insertion to ensure full contact and prevent slippage. Use a drift punch and knockout slot to remove the bit — never hammer the flutes or body directly.
