Precision Twist Drill 6000202 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000202 is a high speed steel extra length drill bit designed for deep-hole drilling applications where standard-length bits fall short. With a 0.4688-inch diameter, a 12-inch overall length, and a 9-inch spiral flute length, this bit handles reach-critical work in fabrication, maintenance, and general machining environments. The uncoated HSS construction is suited for a broad range of workpiece materials. A web-thinned, tapered web configuration reduces thrust at the point, making starts cleaner and feed forces more manageable across varying material types.

This bit is built for use across a wide variety of primary and secondary workpiece materials including aluminum, magnesium, copper, nickel, titanium, stainless steel, malleable iron, nickel alloy, reinforced plastics, and high strength bronze. The 12xD flute-to-diameter ratio makes it the correct choice when standard drill reach is insufficient — common in structural fabrication, pipe and conduit work, thick plate drilling, and deep fixture applications. It is equally at home in a machine shop or on a jobsite where a drill press or portable drill motor is in use.

Key Features

• 0.4688-inch diameter with 12-inch overall length for extended reach drilling
• 9-inch spiral flute length with regular helix for efficient chip evacuation
• Web-thinned, tapered web reduces entry thrust and improves point engagement
• 118-degree standard point angle for general purpose drilling across a wide material range
• Uncoated high speed steel construction — regrindable and field-serviceable
• Right-hand cutting direction, straight-cylindrical shank fits standard drill chucks
• Meets ANSI standards; Series 1290 general purpose grade

Compatibility

Designed for use with standard drill chucks accepting a 0.4687-inch straight-cylindrical shank. Suitable for drilling aluminum, magnesium, copper, nickel, titanium, stainless steel, malleable iron, nickel alloy, reinforced plastic, and high strength bronze as specified by the manufacturer for Series 1290.

Installation Notes

Install into a drill press, magnetic drill, or hand-held drill motor with a chuck rated for the 0.4687-inch shank diameter. Secure the shank fully and verify chuck tightness before operation. Use appropriate cutting fluid for the workpiece material to manage heat and extend tool life. Inspect the cutting edge and web condition before each use; regrind or replace when point geometry is degraded.
