Precision Twist Drill 6001012 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001012 is a taper shank drill bit designed for general-purpose metal drilling in machine shop and production environments. Built from high speed steel with an oxide finish, it accepts a 1MT (Morse Taper 1) spindle and cuts a 0.3438-inch (11/32 inch) diameter hole. The 118-degree standard point with web thinning reduces entry resistance and centers reliably on most ferrous and non-ferrous materials. The right-hand spiral flute evacuates chips efficiently during through-hole and blind-hole operations. This bit is installed and operated by machinists, tool-and-die technicians, and maintenance mechanics working with drill presses, lathes, and milling machines equipped with a 1MT taper socket.

The 6001012 is suited for general-purpose drilling in steel, cast iron, aluminum, and similar materials where a taper shank provides the rigid, self-locking drive needed for larger-diameter work. With a 3.25-inch flute length and 6.5-inch overall length, it handles moderate-depth holes without extension tooling. Its regular spiral geometry and right-hand cutting direction make it compatible with standard machine spindle rotation. The oxide surface treatment offers mild lubricity and corrosion resistance during service and storage.

• High speed steel construction for durability across ferrous and non-ferrous materials
• 3.25-inch spiral flute length supports moderate-depth drilling without chip packing
• Oxide finish provides mild corrosion resistance and surface lubricity
• Meets ANSI standards; Series 209 general-purpose designation

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a No. 1 Morse Taper (1MT) spindle or taper socket, consistent with standard ANSI taper shank tooling specifications.

Installation Notes

Taper shank drill bits are installed by qualified machinists or maintenance mechanics. Always power down and lock out the machine spindle before seating or removing the taper shank. Clean the taper socket and shank surfaces thoroughly before insertion to ensure full contact and prevent slippage under load. Use a drift and drift slot to remove the bit safely — never strike the chuck or spindle housing to dislodge a seated taper.
