Precision Twist Drill 6001486 Taper Shank Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6001486 is a taper shank drill bit designed for general-purpose metal drilling in industrial and shop environments. It carries a Morse Taper 1 (1MT) shank for secure seating in compatible drill presses, lathes, and milling machines. The cutting end is ground to a standard 118-degree point angle with web thinning to reduce thrust and improve penetration. Constructed from high speed steel with an oxide finish, this bit delivers reliable performance across ferrous and non-ferrous materials. Overall length is 7.1563 inches with a flute length of 3.9688 inches, placing it in the 5ATS series and conforming to DIN 345.

This drill bit is suited for production shops, maintenance facilities, and machine shops where taper shank tooling is standard. The 0.4921-inch (12.50 mm) diameter makes it appropriate for through-hole drilling, clearance holes, and stepped bore preparation. The right-hand spiral flute and regular spiral type promote consistent chip evacuation during both manual and CNC-assisted operations. It is installed by machinists, tool-and-die technicians, and maintenance mechanics working with drill presses, engine lathes, and similar taper-socket spindle equipment.

Installation Notes

Installation is performed by machinists or maintenance mechanics. Clean the taper shank and taper socket before seating to ensure full contact and prevent fretting. Drive the shank firmly into the taper socket using a drift if necessary; never use the spindle feed to force engagement. To remove, use the appropriate drift through the spindle slot to break the taper lock safely before handling.
