Precision Twist Drill 6001025 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001025 is a taper shank drill bit engineered for general-purpose metal drilling in machine shop and industrial environments. Built from high speed steel (HSS) with an oxide finish, this bit delivers reliable performance in ferrous and non-ferrous materials. It measures 53/64 inches (0.8281 inches) in diameter with an overall length of 10.75 inches and a flute length of 6.125 inches. The 118-degree standard point angle suits a wide range of drilling applications, and the web-thinned tip reduces thrust requirements for cleaner entry. Right-hand spiral flutes evacuate chips efficiently during operation. Licensed machinists, toolroom technicians, and industrial maintenance mechanics are the typical users.

This bit is suited for use in drill presses, milling machines, and lathes equipped with a No. 3 Morse taper (3MT) spindle or tailstock. It fits standard 3MT toolholders and sleeves common in production and maintenance machining environments. The Series 209 designation indicates a standard-length taper shank configuration built to ANSI tolerances. General-purpose applications include through-hole and blind-hole drilling in steel, cast iron, aluminum, and similar materials at typical machine speeds and feeds for HSS tooling.

Key Features

• 53/64 inch (0.8281 inch) diameter suits common production hole sizes
• No. 3 Morse taper shank provides positive drive and easy spindle mounting
• High speed steel construction handles general-purpose drilling in ferrous and non-ferrous materials
• Oxide finish improves lubricity and provides mild corrosion resistance
• 118-degree standard point angle with web thinning reduces entry thrust
• Right-hand regular spiral flutes promote consistent chip evacuation
• Built to ANSI standards for dimensional accuracy and interchangeability

Compatibility

Designed for use with any machine spindle or tailstock fitted with a No. 3 Morse taper socket, including standard drill presses, engine lathes, and milling machines. Accepts a standard 3MT drift for bit removal.

Installation Notes

Installation is performed by machinists or toolroom technicians. Clean the taper shank and spindle socket thoroughly before seating to ensure full contact and prevent fretting. Insert the bit with the tang aligned to the drive slot and seat it firmly by hand or with a gentle mallet tap. To remove, use a proper Morse taper drift through the spindle drift slot — never pry against the flutes or shank body.
