Precision Twist Drill 6001015 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001015 is a taper shank drill bit designed for general-purpose metal drilling in machine shop and industrial maintenance applications. It carries a 5/8 inch (0.6250 inch decimal) cutting diameter and mounts via a No. 2 Morse Taper (2MT) shank, making it compatible with drill presses, lathes, and milling machines equipped with a 2MT spindle or tailstock. The bit is manufactured from high speed steel with an oxide finish for basic corrosion resistance and reduced friction during cutting. A 118-degree standard point angle and right-hand spiral flute geometry suit it to common ferrous and non-ferrous materials.

This bit fits production drilling, repair, and maintenance work where a taper shank is required for positive shank engagement. The Series 209 designation places it within a general-purpose HSS line conforming to ANSI standards. With a 4-7/8 inch flute length and 8-3/4 inch overall length, it handles moderate depth holes in a range of workpiece materials. The web-thinned point reduces thrust requirements at the cutting tip. Machinists, toolroom technicians, and industrial maintenance mechanics are the primary users of this bit in production and maintenance environments.

Key Features

• 5/8 inch cutting diameter with 0.6250 inch decimal ground size for consistent tolerances
• No. 2 Morse Taper shank for positive engagement in 2MT spindles and tailstocks
• High speed steel construction handles a broad range of ferrous and non-ferrous materials
• Oxide finish provides basic lubricity and corrosion resistance
• 118-degree standard point angle suited to general-purpose drilling applications
• Web-thinned point reduces cutting thrust and improves hole entry
• Right-hand spiral flute with regular helix for consistent chip evacuation

Compatibility

Designed for use in drill presses, lathes, and milling machines fitted with a No. 2 Morse Taper (2MT) spindle socket or tailstock. Conforms to ANSI standards per Series 209 specifications.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle or tailstock is fully de-energized and the quill is locked before seating or removing the taper shank. Clean both the shank taper and the spindle socket thoroughly before insertion to ensure full metal-to-metal contact and prevent shank damage. Use a drift and drift slot to remove the bit from the spindle rather than striking the bit body directly.
