Precision Twist Drill 6000436 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000436 is a taper shank drill bit designed for heavy-duty drilling applications in metal and other hard materials. Built from high speed steel with an oxide finish, this bit features a 1.125-inch diameter, a standard 118-degree point angle, and a right-hand spiral flute configuration. It seats into a No. 3 Morse Taper spindle and delivers a full 11.75 inches of overall length. The web-thinned standard point reduces thrust and improves penetration in general-purpose machining environments. This bit is typically installed by machinists and maintenance technicians working with drill presses, lathes, or milling machine spindles equipped with MT3 sleeves.

This drill bit is suited for general-purpose drilling in ferrous and non-ferrous metals, plastics, and similar materials. The 4xD flute-length-to-diameter ratio and 7.125-inch flute length provide adequate chip evacuation for moderate-depth holes. It is a practical choice for shop environments, maintenance departments, and job sites where a reliable large-diameter taper shank bit is required regularly.

Key Features

• 1.125-inch diameter with a 118-degree standard point angle for general-purpose penetration
• No. 3 Morse Taper (3MT) shank for secure seating in compatible spindles and sleeves
• High speed steel construction with oxide finish for corrosion resistance and reduced friction
• Web-thinned point reduces cutting thrust and improves bit entry
• Right-hand spiral flute with 7.125-inch flute length for effective chip clearance
• ANSI standard compliant, Series S209

Compatibility

Designed for use in drill press spindles, lathe tailstocks, and milling machine quills fitted with a No. 3 Morse Taper socket or appropriate MT3 adapter sleeve.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with Morse Taper tooling. Power down and lock out the machine before inserting or removing the bit. Seat the taper shank firmly by hand and verify it is fully engaged before operating. Use a drift key and soft mallet to remove the bit from the spindle — never attempt to unload a taper shank bit while the spindle is in motion.
