Import 27512 Jobber Length Drill Bit Wire Size 12 Hss

Product Description

The IMPORT 27512 is a jobber length drill bit sized to wire gauge number 12, with a decimal diameter of 0.1890 inches. Constructed from high speed steel with an oxide coating, it is built for general purpose drilling across a wide range of materials including mild steel, aluminum, wood, and plastics. The 118-degree standard point angle allows for easy starting on flat surfaces without a center punch in most applications. With an overall length of 3.5 inches and a flute length of 2.3125 inches, this bit fits standard three-jaw chucks on benchtop and handheld drill equipment. It is commonly installed and used by machinists, electricians, plumbers, HVAC technicians, and general tradespeople.

This drill bit is suited for light to medium-duty production and maintenance drilling tasks in both shop and field environments. The straight-cylindrical shank at 0.1890 inches diameter seats securely in standard drill chucks without adapters. The spiral flute with regular spiral type and tapered web configuration provides efficient chip evacuation during drilling. Web thinning reduces thrust required at breakthrough, making it practical for hand-held drilling operations in tight spaces common to trade work.

Installation Notes

Install and remove drill bits only with the drill unpowered and, for drill press use, with the machine fully stopped. Secure the shank firmly in the chuck and confirm the bit runs true before drilling. For metalworking applications, use appropriate cutting fluid to extend bit life and improve cut quality. Always wear eye protection when drilling.
