Chicago-latrobe 49722 Taper Length Drill Bit 11/32 in Hss

Product Description

The CHICAGO-LATROBE 49722 is a taper length, straight-shank drill bit machined from high speed steel and designed for general-purpose drilling in metal fabrication and maintenance applications. The bit measures 11/32 inch (0.3438 inches) in diameter with a standard 118-degree point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The spiral flute geometry and right-hand cut make it compatible with standard drill presses, milling machines, and hand-held power drills. Diameter tolerance is held to +0.0000 to -0.0010 inches for consistent hole quality.

The 49722 is suited for drilling alloy steel, carbon steel, and cast iron in both shop and field environments. Its taper length body — longer than a jobber bit but shorter than an extra-long series — provides added reach for applications where standard jobber length is insufficient without sacrificing rigidity. Machinists, maintenance technicians, and fabricators working on structural steel, machinery frames, and general metalwork will find this bit well-matched to production and repair drilling tasks alike.

Key Features

• High speed steel construction for durability across steel and cast iron applications
• 118-degree standard point angle suitable for general-purpose metal drilling
• Web-thinned, tapered web reduces cutting thrust and improves drill-through performance
• Right-hand spiral flute promotes efficient chip removal during drilling
• Straight shank compatible with standard drill chucks — no adapter required
• Diameter tolerance of +0.0000 to -0.0010 inches for consistent, repeatable hole sizing

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard 3-jaw chucks accepting straight shanks up to 11/32 inch diameter. Rated for use in alloy steel, carbon steel, and cast iron materials per manufacturer specification.

Installation Notes

Install in a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Apply appropriate cutting fluid when drilling steel or cast iron to extend bit life and improve hole finish. Inspect the cutting edges for wear before each use — a dull or chipped point should be resharpened or the bit replaced before continuing work.
