Precision Twist Drill 6001027 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001027 is a taper shank drill bit designed for general-purpose drilling in metal, wood, and similar materials. Built from high speed steel with an oxide finish, it handles demanding shop and field applications where a Morse taper spindle is available. The bit measures 0.4063 inches (13/32 inches) in diameter with a 7-inch overall length and a 3.625-inch spiral flute. The 118-degree standard point with web thinning promotes clean entry and reduces walking on entry. Right-hand cutting direction and regular spiral geometry suit a wide range of production and maintenance drilling tasks. Licensed machinists, millwrights, and tool-room technicians are the primary installers of this bit type.

This drill bit is suited for use in drill presses, lathes, and milling machines equipped with a No. 1 Morse taper (1MT) spindle or sleeve. It fits standard 1MT tooling adapters and sleeves commonly found in light manufacturing, maintenance shops, HVAC fabrication, and plumbing rough-in environments where taper shank tooling is standard. The general-purpose tool performance rating makes it appropriate for intermittent production drilling in mild steel, cast iron, aluminum, and thermoplastics. It conforms to ANSI standards for taper shank drill geometry.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Power down and lock out the machine before seating or removing the taper shank. Clean both the spindle taper bore and the shank with a clean cloth before insertion to ensure full taper contact and prevent slippage. Never use a chuck to hold a taper shank bit; use the correct 1MT sleeve or drift key for removal.
