Import 27425 Jobber Length Drill Bit 8.5 Mm Hss

Product Description

The IMPORT 27425 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and similar materials. Built from high speed steel with an oxide coating, it handles repeated use in production and maintenance environments. The bit measures 8.5 mm (0.3346 inches) in diameter with a standard 118-degree point angle and a regular spiral flute for efficient chip evacuation. Overall length is 4-49/64 inches, and the straight-cylindrical shank seats securely in standard drill chucks. Right-hand cutting direction is standard for conventional drilling operations. This bit suits machinists, maintenance technicians, and trade professionals who need a reliable general-purpose drill in metric sizing.

The 27425 is suited for light to medium drilling tasks in shop, field, and maintenance settings. Its 8.5 mm diameter places it in the 8.00 to 9.00 mm size range, making it a common selection for clearance holes, pilot holes, and through-hole applications across metal fabrication, HVAC installation, plumbing rough-in, and electrical work. The web-thinned, tapered web configuration reduces thrust requirements and improves point stability at the start of a cut. Sold individually, with a minimum order quantity of 6 units per order.

Installation Notes

Install the bit securely in a properly sized drill chuck and confirm it is centered before applying power. Always wear appropriate eye protection and secure the workpiece before drilling. For metal drilling, use cutting fluid where applicable to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
