Precision Twist Drill 6001000 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001000 is a taper shank drill bit designed for general-purpose metal drilling applications. Built from high speed steel (HSS) with an oxide finish, this bit measures 0.25 inches (Letter E) in diameter with a 6.125-inch overall length and a 2.875-inch spiral flute. The 118-degree standard point geometry with web thinning reduces thrust and improves chip evacuation on entry. It mounts via a 1MT (Morse Taper 1) shank, making it compatible with drill presses, lathes, and milling machines equipped with a matching taper spindle. Right-hand cutting direction is standard for conventional clockwise-rotation equipment.

This bit is suited for use in machine shop and industrial maintenance environments where a taper shank interface is required for positive drive and accurate hole location. The Series 209 design conforms to ANSI standards and is built for regular spiral, right-hand cutting in ferrous and non-ferrous metals. Typical users include machinists, tool-and-die technicians, and maintenance professionals working with drill presses or lathes that accept a 1MT taper. The general-purpose performance rating makes it appropriate for production or repair work in mild steel, aluminum, and similar materials.

Key Features

• High speed steel construction with oxide finish for corrosion resistance and reduced friction
• 1MT (Morse Taper 1) shank for positive, self-holding engagement in compatible spindles
• 118-degree standard point with web thinning to lower entry thrust and improve chip flow
• 2.875-inch flute length providing a 4xD flute-to-diameter ratio for efficient chip clearance
• Right-hand, regular spiral flute geometry suited for general-purpose metal drilling
• Conforms to ANSI standards, Series 209

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a 1MT (Morse Taper 1) spindle or adapter. No specific OEM model compatibility data was provided in the product information.

Installation Notes

Installation requires a machine spindle or drill chuck adapter with a 1MT taper socket. Clean the taper shank and spindle bore of oil and debris before seating to ensure full contact and prevent slippage. Power down and lock out the machine before inserting or removing the bit. A drift punch and mallet are the standard tools for ejecting a taper shank bit from the spindle.
