Precision Twist Drill 6001263 Taper Shank Drill Bit 1MT

Product Description

The PRECISION TWIST DRILL 6001263 is a taper shank drill bit designed for general-purpose metal drilling in machine shop and industrial environments. Built from high speed steel with an oxide finish, this bit measures 0.1969 inches (5.00 mm) in diameter and carries a 1MT (Morse Taper 1) shank for secure mounting in compatible drill press spindles and lathes. The 118-degree standard point with web thinning reduces entry force and improves centering on flat stock. Overall length is 5.2362 inches with a flute length of 2.0472 inches, making it suitable for moderate-depth hole applications. Right-hand spiral flutes clear chips efficiently during drilling. This bit conforms to DIN 345 standards and belongs to the Series 5ATS product line.

This drill bit is suited for production drilling, toolroom work, and general machining operations where a taper shank interface is required. The 1MT shank fits standard Morse Taper 1 spindles found on bench drill presses, floor-standing drill presses, and manual lathes commonly used in light industrial and fabrication settings. The general-purpose designation makes it appropriate for mild steel, aluminum, brass, and similar machinable materials. Machinists, tool-and-die workers, and maintenance mechanics are the primary installers of this bit type.

Installation Notes

Installation and removal of taper shank tooling should be performed by a qualified machinist or maintenance technician. Always power down and lock out the machine before inserting or removing the bit from the spindle. Use a proper drift and drift slot to eject the taper shank; never strike the bit body directly. Verify the taper socket is clean and free of chips or burrs before seating to ensure full contact and prevent spindle damage.
