Precision Twist Drill 6000476 Taper Shank Drill Bit

Product Description

The PRECISION TWIST DRILL 6000476 is a taper shank drill bit engineered for heavy-duty drilling in metal fabrication, machining, and industrial maintenance applications. Built from high speed steel with an oxide finish, this bit features a 1.1875-inch diameter, a 118-degree standard point angle, and a right-hand spiral flute for consistent chip evacuation. The web-thinned point reduces thrust force at entry and improves centering on tough materials. Machinists and tool-and-die tradespeople rely on this series for general-purpose drilling where a Morse taper spindle is the standard interface.

This drill bit is suited for use in radial arm drill presses, vertical knee mills, and large drill press columns equipped with a No. 3 Morse taper (3MT) spindle socket. The 12-inch overall length and 7.375-inch flute length accommodate deep-hole drilling requirements common in plate work and heavy structural fabrication. The regular spiral geometry and oxide surface treatment make it appropriate for ferrous and non-ferrous metals under general-purpose cutting conditions without coolant-through capability.

Key Features

• 1.1875-inch (1-3/16 inch) diameter for large-bore drilling in plate and structural stock
• No. 3 Morse taper shank for direct mounting in compatible spindles without a chuck
• High speed steel construction with oxide finish for corrosion resistance and reduced friction
• 118-degree standard point angle with web-thinned tip to reduce entry thrust
• 7.375-inch flute length supports deep-hole drilling at a 4xD ratio
• Right-hand, regular spiral flute for efficient chip clearing
• ANSI-standard Series S209 geometry for consistent dimensional compliance

Compatibility

Designed for use in drill press spindles, milling machine quills, and lathes fitted with a No. 3 Morse taper (3MT) receiver socket.

Installation Notes

Installation requires a 3MT spindle or a compatible Morse taper adapter sleeve. Always power down and lock out the machine before seating or removing the taper shank. Seat the taper with a firm hand push to ensure full engagement before starting the spindle. Use appropriate cutting fluid for the material being drilled to extend tool life and maintain dimensional accuracy.
