Precision Twist Drill 6001493 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001493 is a taper shank drill bit designed for accurate, high-torque drilling in metal fabrication and machine shop environments. Built from high speed steel with an oxide finish, it cuts a 0.5315-inch diameter hole and mounts via a No. 1 Morse taper shank for positive engagement in compatible spindles and tailstocks. The 118-degree standard point with web thinning reduces thrust and improves penetration on entry. At 7.4409 inches overall length with a 4.252-inch spiral flute, it handles moderate-depth through-holes in a single pass. General-purpose performance rating makes it suitable for a wide range of ferrous and non-ferrous materials.

This bit is intended for use in drill presses, lathes, and milling machines equipped with a No. 1 Morse taper socket. It suits production drilling, maintenance, and repair operations in industrial, commercial, and job-shop settings. The right-hand cutting direction and regular spiral flute geometry support standard drilling operations without the need for specialized toolholders. Machinists and tool-and-die professionals typically reach for this style when working with steel, cast iron, aluminum, and similar materials where a rigid taper-mount connection is required over a straight-shank alternative.

Key Features

• High speed steel construction for durability across general-purpose drilling applications
• Oxide finish for basic lubricity and corrosion resistance during storage and use
• No. 1 Morse taper shank provides rigid, self-holding connection in compatible spindles
• 118-degree standard point with web thinning reduces entry thrust and improves hole accuracy
• Regular right-hand spiral flute evacuates chips efficiently during through-hole drilling
• Meets DIN 345 standard for taper shank drill bit geometry and tolerances

Compatibility

Designed for use in drill press spindles, lathe tailstocks, and milling machine quills fitted with a No. 1 Morse taper socket. Part of the PRECISION TWIST DRILL Series 5ATS.

Installation Notes

Installation is performed by machinists or tool-and-die professionals. Power down and lock out the machine before inserting or removing the taper shank. Clean both the shank and the taper socket with a clean cloth before seating to ensure full contact and prevent fretting. Never drive the shank in with a hammer; use the machine draw bar or a properly sized drift and drift slot to seat and release the bit safely.
