Precision Twist Drill 6001144 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6001144 is a taper shank drill bit designed for general-purpose metal drilling in shop and field environments. It is built from high speed steel with an oxide finish and features a right-hand spiral flute for efficient chip evacuation. The bit measures 0.375 inches in diameter with a 6.75-inch overall length and a 3.5-inch flute length. The 118-degree standard point geometry with web thinning makes it suitable for starting on flat or curved surfaces without excessive thrust. Licensed machinists, tool-and-die workers, and maintenance mechanics are the primary installers for this type of tooling.

This drill bit is intended for use in drill presses, lathes, and milling machines equipped with a No. 1 Morse Taper (1MT) spindle or sleeve. It handles general-purpose drilling in mild steel, cast iron, aluminum, and similar materials. The Series 209 designation places it in a standard production line conforming to ANSI specifications. It is well suited for production shops, maintenance departments, and job-site drilling rigs where a reliable, consistent taper shank bit is needed for 3/8-inch bore work.

Key Features

• 0.375-inch diameter with 1MT taper shank for positive spindle engagement
• High speed steel construction for durability across common metalworking materials
• Oxide finish provides mild corrosion resistance and reduced friction
• 118-degree standard point with web thinning reduces walking and lowers required thrust
• Right-hand spiral flute promotes efficient chip removal during through-drilling
• ANSI-conforming Series 209 design ensures dimensional consistency

Compatibility

Designed for use in drill press spindles, lathe tailstocks, and milling machine quills fitted with a No. 1 Morse Taper socket or a compatible 1MT sleeve adapter.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with rotating cutting tools and machine tool safety. Power down and lock out the machine before inserting or removing the taper shank bit from the spindle. Seat the taper fully by hand and verify it is clean and free of chips before engaging the spindle. Always operate within the spindle speed range appropriate for the workpiece material and bit diameter per standard machining practice.
