Precision Twist Drill 5997169 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5997169 is a taper length, high speed steel drill bit designed for precise, clean-entry drilling across a wide range of metals and alloys. It measures 0.0635 inches in diameter (Wire Size 52) with a 2-inch parabolic flute and an overall length of 3-3/4 inches. The 135-degree split point promotes self-centering on contact, reducing the need for a center punch on most surfaces. The bright, uncoated finish suits general-purpose production and maintenance drilling. This bit is installed and used by machinists, pipefitters, electricians, and general trade professionals working in fabrication or field service environments.

The 5997169 fits standard straight-shank drill chucks and is suited for both handheld and bench-mounted drilling applications. Its parabolic flute geometry and web-thinned, tapered web configuration improve chip evacuation and reduce thrust on harder materials. It is appropriate for light production runs and maintenance drilling where hole accuracy and clean entry matter. The 6xD flute-to-diameter ratio allows for deeper drilling relative to bit diameter without packing chips. This bit conforms to ANSI standards for taper length drill geometry.

Key Features

• 135-degree split point for self-centering entry without a center punch
• Parabolic flute with web-thinned tapered web for efficient chip removal
• High speed steel construction rated for heavy-duty general-purpose use
• Bright, uncoated finish compatible with cutting fluids and dry drilling
• Straight shank fits standard drill chucks; no threaded shank or coolant-through requirement
• ANSI-conforming taper length geometry for consistent dimensional accuracy

Compatibility

Rated for use in alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, magnesium, magnesium alloy, malleable iron, nickel, stainless steel, steel, tempered steel, titanium, and titanium alloy. Fits any standard straight-shank drill chuck accepting a 0.0635-inch shank.

Installation Notes

Install in a keyed or keyless straight-shank chuck and tighten securely before operation. Confirm chuck capacity is rated to accept the 0.0635-inch shank diameter. Use appropriate cutting fluid for harder materials such as stainless steel, hardened steel, or titanium to extend tool life and maintain hole quality. Inspect the cutting edges for wear before each use; a dull split-point tip will increase thrust and risk bit walking.
