Precision Twist Drill 6001070 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001070 is a taper shank drill bit designed for drilling precise, clean holes in metal and other hard materials. Built from high speed steel with an oxide finish, it resists heat and wear during heavy-duty cutting operations. The bit features a standard 118-degree point angle with web thinning to reduce thrust and improve centering at the start of each bore. At 11.0625 inches overall length with a 6.3125-inch spiral flute, this bit handles deep-hole applications where rigidity and chip evacuation matter. It is sized at 0.9449 inches (24.00 mm) in diameter and carries a 3MT taper shank for secure mounting in compatible spindles. Machinists, tool-and-die workers, and general fabrication shops are the primary users.

This drill bit suits general-purpose metal drilling in production and job-shop environments. The 3MT taper shank seats directly into taper-socket drill press spindles, milling machine quills, or lathe tailstocks equipped with a Morse taper 3 socket. The regular right-hand spiral and standard point geometry make it a reliable choice for ferrous metals, cast iron, and similar materials where a general-purpose HSS bit meets the application requirements. The 4xD flute-to-diameter ratio supports adequate chip clearance in moderate-depth bores.

Installation Notes

Installation and removal of taper shank tooling should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine before seating or drifting out the taper shank. Use a proper drift key in the spindle slot to remove the bit — do not strike the bit directly. Confirm the taper socket is clean and free of burrs before seating to ensure full contact and prevent spindle damage.
