Precision Twist Drill 5999684 Taper Length Drill Bit 11/32

Product Description

The PRECISION TWIST DRILL 5999684 is a taper length drill bit designed for general-purpose drilling across a wide range of materials. Built from high speed steel with a bright/uncoated finish, this 11/32 inch (0.3438 inches) diameter bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight shank and right-hand spiral flute make it compatible with standard drill chucks. It is sized for use by machinists, maintenance technicians, and trade professionals who need reliable performance in production and field applications.

This bit is suited for drilling alloy steel, carbon steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, nickel, nickel alloy, magnesium, magnesium alloy, cermet, graphite, and reinforced plastic materials. Its taper length body — longer than a jobber bit — provides additional reach for deeper hole applications without requiring an extension. The Series R51 designation identifies it as a current production, general-purpose tool conforming to ANSI standards.

Key Features

• 11/32 inch (0.3438 inches) diameter with a 4-1/8 inch flute length and 6.5 inch overall length
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction for durability across ferrous and non-ferrous materials
• Right-hand cut, regular spiral flute for efficient chip removal
• Bright/uncoated finish — no heat treatment alteration, suitable for re-sharpening
• ANSI-compliant Series R51 taper length design

Compatibility

Designed as a general-purpose taper length replacement drill bit conforming to ANSI standards, suitable for use in standard straight-shank drill chucks across bench drills, drill presses, and hand-held drill motors.

Installation Notes

Install in a compatible straight-shank drill chuck and verify the shank is fully seated and chuck jaws are evenly tightened before operation. Use appropriate cutting fluid or coolant for ferrous materials to extend tool life, even though this bit does not feature through-coolant capability. Operate at speeds appropriate for the workpiece material and bit diameter per standard machining reference tables. Inspect the cutting edges before each use and resharpen or replace if chipping or dulling is observed.
