Precision Twist Drill 6001476 Taper Shank Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6001476 is a taper shank drill bit designed for accurate hole-making in metal, wood, and general-purpose materials. It carries a Morse Taper 1 (1MT) shank, which seats directly into compatible taper-shank spindles and drill press quills without an additional chuck. The cutting end is ground to a 118-degree standard point with web thinning to reduce thrust and improve centering. The body is high speed steel (HSS) with an oxide finish that provides light corrosion resistance and helps retain lubrication during drilling. This bit is sized at 0.4331 inches (11.00 mm) and has an overall length of 6.875 inches.

This drill bit is suited for general-purpose production and maintenance drilling on the bench drill press or floor-standing drill press in machine shops, maintenance departments, and fabrication environments. The 1MT taper shank allows direct mounting in drill presses and lathes equipped with a No. 1 Morse Taper socket. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling in mild steel, cast iron, aluminum, and similar materials. It conforms to DIN 345 standards, making it a direct fit for metric-dimensioned tooling setups that require an 11.00 mm diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with taper-shank tooling. Power down and lock out the machine before seating or removing the bit. Clean both the taper shank and the spindle socket thoroughly before insertion to ensure full metal-to-metal contact and prevent fretting. Use a drift and knockout bar to remove the bit from the spindle; do not strike the bit body directly.
