Import 27547 Jobber Length Drill Bit Wire Size 47 Hss

Product Description

The IMPORT 27547 is a wire-gauge jobber length drill bit sized at No. 47 (0.0785 inches decimal equivalent), manufactured from high speed steel with an oxide coating for added surface hardness and corrosion resistance. It features a standard 118-degree split point, a regular spiral flute, and a straight-cylindrical shank. The web-thinned, tapered web configuration reduces thrust during entry and helps center the bit without a pilot hole. At 2 inches overall length with a 1-inch flute, this is a compact, general-purpose bit suited for light metal, plastic, and wood drilling in production and maintenance applications.

This bit is intended for general-purpose drilling in fabrication shops, maintenance facilities, HVAC and plumbing rough-in work, and electrical trade applications where small-diameter precision holes are required. The No. 47 wire gauge size is commonly used when threading for small machine screws or creating pilot holes in thin-gauge sheet metal and enclosures. Right-hand cutting direction is standard for use in conventional drill presses and hand drills.

Key Features

• Wire size No. 47 with 0.0785-inch decimal diameter for precise small-bore applications
• High speed steel construction handles moderate heat buildup during cutting
• Oxide finish provides surface protection and mild lubricity
• 118-degree standard point angle suits a wide range of common materials
• Web-thinned tapered web reduces entry thrust and improves centering
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard keyed or keyless drill chucks accepting a 0.0785-inch straight shank across drill presses, hand drills, and CNC equipment in the No. 47 wire gauge size range.

Installation Notes

Installed by machinists, maintenance technicians, and trade professionals using conventional drill presses or hand drills. Secure the shank fully in the chuck before operation and verify chuck key is removed before powering the tool. Use appropriate cutting fluid or lubrication when drilling ferrous metals to extend bit life. Inspect the cutting edges for wear or chipping before each use, as small-diameter bits are susceptible to breakage under side load or excessive feed pressure.
