Precision Twist Drill 6001112 Taper Shank Drill Bit 25/64

Product Description

The PRECISION TWIST DRILL 6001112 is a taper shank drill bit designed for drilling precise, clean holes in metal and general-purpose materials. Built from high speed steel with an oxide finish, it measures 0.3906 inches (25/64 inch) in diameter with a 118-degree standard point angle and a right-hand spiral flute. The Morse Taper 1 shank seats directly into compatible drill press spindles or lathe tailstocks without a separate chuck, providing rigid, concentric tool holding. Machinists and maintenance technicians reach for this bit when the application calls for a positive-drive shank connection and consistent hole geometry in production or shop floor environments.

The 6001112 is suited for general-purpose drilling operations in ferrous and non-ferrous metals, plastics, and similar materials. The 7.0-inch overall length and 3.625-inch flute length give it reach for deeper holes that standard jobber-length bits cannot access. The web-thinned standard point reduces thrust and improves chip evacuation at the start of the cut. This bit is a practical choice for machine shops, maintenance departments, and fabrication operations running drill presses or lathes equipped with a No. 1 Morse Taper spindle socket.

Key Features

• No. 1 Morse Taper shank for rigid, chuckless mounting in compatible spindles
• High speed steel construction handles general-purpose drilling in metal and plastics
• Oxide finish provides light corrosion resistance and reduced friction
• 118-degree standard point with web thinning reduces entry thrust and improves chip flow
• Right-hand spiral flute with regular spiral geometry for reliable chip evacuation

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a No. 1 Morse Taper (1MT) spindle socket or tailstock.

Installation Notes

Installation is performed by machinists or qualified maintenance technicians. Before mounting or removing the bit, ensure the machine spindle is fully stopped and locked out per applicable lockout/tagout procedures. Clean the taper shank and the spindle socket thoroughly before seating to ensure full contact and prevent runout. Use a drift and soft mallet in the spindle drift slot to remove the bit safely — never strike the bit body directly.
