Import 27553 Jobber Length Drill Bit Wire Size 53 Hss

Product Description

The IMPORT 27553 is a jobber-length twist drill bit sized to wire gauge 53 (0.0595 inches decimal equivalent) and built from high speed steel with an oxide coating. It features a 118-degree standard point angle and a spiral, regular-helix flute ground to 0.875 inches in length. The straight-cylindrical shank matches the 0.0595-inch body diameter for direct chuck mounting. This is a general-purpose bit suited to metalworking, light fabrication, and maintenance drilling tasks handled by machinists, pipefitters, electricians, and general mechanical tradespeople. Overall length is 1.875 inches.

Wire gauge drill bits in the 53 range are commonly used for tapping clearance holes, pilot holes in sheet metal, and precision hole work in light steel, aluminum, brass, and plastic. The oxide finish provides a degree of lubricity and corrosion resistance during dry or lightly lubricated drilling. The web-thinned, tapered-web point geometry helps center the bit and reduces feed pressure on thin-gauge material. This bit is sold as a single unit with a minimum order quantity of 12 pieces per order, making it practical for shop stocking and field kit replenishment.

Key Features

• Wire size 53 — 0.0595 inches decimal equivalent for precision hole sizing
• 118-degree standard point angle with web-thinned, tapered-web geometry for accurate starting
• High speed steel construction for durability across general metalworking applications
• Oxide coating improves lubricity and surface protection during drilling
• Regular spiral flute, 0.875 inches long, promotes chip evacuation in shallow holes
• Straight-cylindrical shank for direct mounting in standard drill chucks and collets

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks, collets, and drill press spindles accepting a 0.0595-inch straight shank.

Installation Notes

This bit is installed by machinists and general trade technicians using hand drills, drill presses, or milling machines. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use cutting fluid or light machine oil when drilling ferrous metals to extend bit life. Inspect the cutting edges before each use — small-diameter high speed steel bits are susceptible to chipping if subjected to side loading or excessive feed pressure.
