Precision Twist Drill 6001287 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001287 is a taper shank drill bit designed for precision hole-making in metal and general-purpose machining applications. It carries a 1MT (Morse Taper 1) shank, a 0.2677-inch (6.80 mm) cutting diameter, and a 118-degree standard point angle with web thinning to reduce thrust on entry. The flute length runs 2.7165 inches and the overall length is 5.9055 inches. Constructed from high speed steel with an oxide finish, this bit handles moderate-speed drilling in a range of ferrous and non-ferrous materials. It follows a right-hand spiral, regular helix configuration and conforms to DIN 345 standards.

This drill bit fits machine tool spindles and drill press quills equipped with a No. 1 Morse Taper socket. It is suited for production and maintenance drilling in job shops, tool rooms, and industrial maintenance environments. The general-purpose performance rating makes it appropriate for structural steel, mild alloys, and similar workpiece materials. The web-thinned point reduces walking on entry and lowers cutting force at the tip, which is useful when working on a manual or semi-automatic drill press without a pilot hole.

Key Features

• 1MT taper shank for direct spindle mounting in No. 1 Morse Taper machines
• 118-degree standard point with web thinning for reduced entry thrust
• High speed steel construction with oxide finish for general-purpose cutting
• Right-hand spiral, regular helix flute for consistent chip evacuation
• Conforms to DIN 345 dimensional standard
• 4xD flute-length-to-diameter ratio for balanced chip clearance and rigidity

Compatibility

Designed for use in drill presses, milling machines, and lathes equipped with a No. 1 Morse Taper (1MT) spindle socket, consistent with DIN 345 taper shank drill specifications.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine before inserting or removing the taper shank. Clean the spindle socket and shank taper of chips, oil, and debris before seating to ensure full contact and prevent runout. Use a drift and drift slot to remove the bit — never strike the spindle housing directly.
