Precision Twist Drill 6000998 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000998 is a taper shank drill bit designed for high-speed steel cutting in metal fabrication and general machining applications. It features a 0.5-inch diameter, a No. 2 Morse taper (2MT) shank for secure spindle engagement, and a 118-degree standard point angle for accurate hole entry on a wide range of workpiece materials. The oxide finish provides moderate lubricity and corrosion resistance during operation. At 8.25 inches overall length with a 4.375-inch spiral flute, this bit is suited for drilling through moderate stock depth with consistent chip evacuation. Right-hand cutting direction and regular spiral geometry support standard drill press and lathe operations.

This drill bit is built for general-purpose metal drilling in production shops, maintenance environments, and tool rooms. The 2MT taper shank mates directly with drill press quills, lathe tailstocks, and milling machine spindles equipped with a No. 2 Morse taper socket or sleeve. It is appropriate for use on steel, cast iron, aluminum, and similar materials where a half-inch through-hole is required. The web-thinned point reduces thrust requirements at breakthrough, making it practical for both manual and CNC-assisted drilling cycles.

Key Features

• No. 2 Morse Taper (2MT) shank for direct spindle mounting without a drill chuck
• 118-degree standard point angle with web-thinned tip for reduced feed force
• High speed steel construction for durability across general-purpose metals
• Oxide finish for improved lubricity and surface protection
• Right-hand cutting, regular spiral flute for efficient chip removal
• Meets ANSI standards; Series 209

Compatibility

Designed for use with drill presses, lathe tailstocks, and milling machine spindles fitted with a No. 2 Morse taper (2MT) socket or adapter sleeve.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle or tailstock is fully powered down and at rest before seating or removing the taper shank. Clean both the shank taper and the receiving socket with a clean cloth before insertion to ensure full taper contact and prevent slippage under load. A drift key and drift slot should be used for proper removal — do not strike the bit directly to dislodge it.
