Precision Twist Drill 5999088 Jobber Drill Bit Wire 49

Product Description

The PRECISION TWIST DRILL 5999088 is a jobber-length drill bit sized to wire gauge 49 (0.0730 inches decimal), manufactured from high speed steel with a bright uncoated finish. It features a standard 118-degree split-point tip and a regular spiral flute for efficient chip evacuation during general-purpose drilling operations. The 2-inch overall length and straight cylindrical shank make it compatible with standard drill chucks on handheld drills, drill presses, and CNC equipment. It is part of the R18P series and is installed by machinists, maintenance technicians, pipefitters, and fabricators across metal fabrication and mechanical service environments.

This bit is designed for drilling into a wide range of materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. With a 14xD flute-to-diameter ratio and a 1-inch maximum drilling depth, it suits precision drilling tasks in sheet metal, structural components, and mechanical assemblies where tight-tolerance hole sizing is required. It is a single-piece unit, sold individually, and is appropriate for both production drilling runs and field service applications.

Key Features

• Wire gauge 49 sizing at 0.0730 inches decimal diameter for tight-tolerance hole requirements
• 118-degree standard point angle with web-thinned, tapered web configuration for reduced entry force
• High speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Regular right-hand spiral flute with 1-inch flute length for effective chip clearing
• Straight cylindrical shank fits standard drill chucks without adapters
• Meets ANSI standards for general-purpose jobber-length drill bits

Compatibility

Designed as a general-purpose OEM-style jobber-length drill bit suitable for use in standard three-jaw drill chucks on handheld, bench, and CNC drilling equipment. Compatible with workpiece materials coded P, M, K, N, and S per the supplier specification, covering steel, stainless steel, cast iron, non-ferrous metals, and superalloys.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a drill press, handheld power drill, or CNC spindle. Secure the straight shank firmly in the chuck and verify concentricity before operation. Coolant-through is not supported on this bit, so apply cutting fluid externally when drilling hard or heat-sensitive materials. Follow applicable ANSI safety standards for rotating tool operation and wear appropriate eye protection.
