Precision Twist Drill 6000160 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000160 is a taper length drill bit designed for general-purpose drilling across a wide range of materials. It measures 0.0890 inches in diameter (Wire Size 43) with an overall length of 4.25 inches and a flute length of 2.25 inches. Constructed from high speed steel with a bright uncoated finish, it features a standard 118-degree split point, a web-thinned and tapered web configuration, and a right-hand spiral flute. This bit is installed and used by machinists, maintenance technicians, pipefitters, and general trade professionals who require consistent performance in production or field drilling operations.

The 6000160 is suited for drilling alloy steel, carbon steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, magnesium, magnesium alloy, nickel, nickel alloy, reinforced plastic materials, graphite, cermet, and hardened steel. Its taper length body provides added rigidity compared to jobber-length bits, making it a practical choice when drilling deeper holes where a standard-length bit would flex or deflect. The straight shank fits standard drill chucks without adapters.

Key Features

• 0.0890 inch diameter, Wire Size 43, taper length configuration for extended reach with added rigidity
• High speed steel construction for durability across a broad range of workpiece materials
• 118-degree standard point angle with web-thinned, tapered web for easier penetration and reduced thrust
• Right-hand regular spiral flute, 6xD flute-to-diameter ratio, for efficient chip evacuation
• Bright uncoated finish — no coating buildup to affect dimensional tolerance in tight-clearance holes
• Straight shank, 0.0890 inches diameter, fits standard drill chucks directly
• Meets ANSI standards; Series R52 general purpose grade

Compatibility

Designed as a general-purpose taper length drill bit compatible with any standard drill chuck or drilling machine that accepts a 0.0890 inch straight shank. Suitable for use in hand drills, drill presses, lathes, and CNC drilling equipment where Wire Size 43 tooling is specified.

Installation Notes

Install in a clean, properly sized drill chuck and tighten securely before operation to prevent shank slippage. Ensure the workpiece is clamped or fixtured before drilling to prevent bit walking, especially at small diameters. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this bit does not support coolant-through delivery. Inspect the cutting edges for wear or chipping before each use and replace when point geometry is compromised.
