Precision Twist Drill 6001152 Taper Shank Drill Bit 31/64

Product Description

The PRECISION TWIST DRILL 6001152 is a taper shank drill bit designed for drilling precise holes in metal and other materials where a Morse taper spindle interface is required. Built from high speed steel with an oxide finish, this bit measures 31/64 inch (0.4844 inches) in diameter and carries a Series 209 designation conforming to ANSI standards. The 118-degree standard point geometry and right-hand spiral flute make it a reliable general-purpose cutting tool suited for production and maintenance drilling operations. Licensed HVAC technicians, pipefitters, machinists, and maintenance tradespeople regularly reach for this class of bit when working with drill presses or lathes equipped with a No. 2 Morse taper spindle.

This bit is intended for general-purpose drilling in ferrous and non-ferrous metals, plastics, and similar materials. The 2MT shank seats directly into compatible drill press spindles, lathe tail stocks, or taper-shank adapters without a separate chuck. The web-thinned standard point reduces thrust and improves chip evacuation at the start of the cut. Typical applications include drilling bolt clearance holes, conduit knockout pilots, and precision through-holes in fabrication and field service settings where a chuck-style bit would be inadequate for the spindle type available.

Key Features

• 31/64 inch (0.4844 inches) diameter for precise hole sizing
• No. 2 Morse Taper (2MT) shank seats directly in compatible spindles without a chuck
• High speed steel construction provides heat resistance for metal drilling
• Oxide finish improves lubricity and corrosion resistance during cutting
• 118-degree standard point angle with web thinning reduces entry thrust
• Right-hand regular spiral flute promotes efficient chip removal
• Meets ANSI standards for dimensional consistency

Compatibility

Designed as an OEM-style general-purpose replacement for No. 2 Morse Taper taper shank drill bits; fits drill presses, lathe tail stocks, and milling machine spindles equipped with a 2MT receptacle.

Installation Notes

Installation is performed by machinists or qualified tradespeople familiar with Morse taper tooling. Power down and lock out the machine before seating or removing the bit. Clean both the taper shank and the spindle socket of chips, oil, and debris before seating to ensure full contact and prevent chatter. Remove the bit using a drift key through the spindle slot — never strike the bit directly against a hard surface to dislodge it.
