Import 27554 Jobber Drill Bit Wire Size 54 Hss

Product Description

The IMPORT 27554 is a jobber-length drill bit sized to wire gauge 54, equivalent to 0.0550 inches decimal. Made from high speed steel with an oxide coating, it delivers consistent performance in general-purpose drilling applications across metal, wood, and composite materials. The bit features a standard 118-degree point angle, right-hand spiral flute, and a straight cylindrical shank. Overall length is 1-7/8 inches with a flute length of 7/8 inch. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation, making it well-suited for precision small-diameter work.

This bit is intended for general-purpose use in light industrial, maintenance, and fabrication settings. The wire gauge 54 size targets fine-tolerance drilling tasks such as pilot holes, tapping preparation, and small-diameter through-holes in sheet metal or thin-wall tubing. It is appropriate for use in drill presses and hand-held electric drills where a straight cylindrical shank is required. No coolant-through capability is present, so conventional cutting fluid applied externally is the standard practice for extended run applications.

Key Features

• Wire gauge 54 size, 0.0550 inches decimal diameter
• High speed steel construction with oxide finish for wear resistance
• 118-degree standard point angle with web-thinned tapered web for reduced entry thrust
• Right-hand cut, regular spiral flute for efficient chip removal
• Straight cylindrical shank compatible with standard drill chucks
• General-purpose grade suited for metal, wood, and composite materials

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.0550-inch straight cylindrical shank across bench-top drill presses and portable electric drills.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling to avoid deflection at this small diameter. Use the lowest practical feed rate and apply external cutting fluid when drilling ferrous metals to extend bit life. Ensure the workpiece is clamped securely to prevent walking at entry. Inspect the point for wear regularly, as small-diameter HSS bits are susceptible to tip damage under excessive heat or lateral load.
