Import 27550 Jobber Length Drill Bit Wire 50 Hss

Product Description

The IMPORT 27550 is a jobber-length twist drill bit designed for general-purpose drilling in metal, plastic, and similar materials. Built from high speed steel with an oxide coating for improved wear resistance, this bit carries a wire gauge size of 50, which corresponds to a decimal diameter of 0.0700 inches. The 118-degree standard point angle and right-hand spiral flute geometry suit a wide range of production and maintenance drilling tasks. Overall length is 2 inches with a 1-inch flute length, making it compact and rigid for small-diameter work. The tapered web with web thinning reduces thrust requirements and helps maintain point stability during entry.

This bit is suited for light-duty production drilling, maintenance and repair work, and tool room applications where a small wire-gauge size is required. The straight-cylindrical shank accepts standard three-jaw drill chucks on benchtop drill presses, hand drills, and CNC machining centers. It is a general-purpose grade bit appropriate for technicians and tradespeople who need a reliable small-diameter drill for sheet metal, junction boxes, brackets, and similar trade applications.

Key Features

• Wire size 50 (0.0700 inches) for small-diameter precision holes
• High speed steel construction with oxide coating for improved surface hardness
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Regular spiral flute, right-hand cut for conventional drilling setups
• Straight-cylindrical shank fits standard three-jaw drill chucks
• Jobber-length body provides a balanced reach-to-rigidity ratio

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any standard three-jaw drill chuck accepting a 0.0700-inch straight-cylindrical shank.

Installation Notes

Installation is performed by a machinist, HVAC technician, electrician, or plumber using a hand drill or drill press. Secure the shank fully in the chuck and confirm the bit runs true before drilling. Always use appropriate cutting fluid or lubrication when drilling metal to extend bit life. Ensure the workpiece is clamped or secured before applying drilling pressure.
