Import -22381-B Jobber Drill Bit 1/2 Inch Hss 118 Deg

Product Description

The IMPORT -22381-B is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high-speed steel (HSS) with a bright, uncoated finish, it measures 0.5 inches in diameter with a 6-inch overall length and a 4.5-inch flute length. The 118-degree standard point angle suits a wide range of common drilling tasks. A web-thinned, tapered web design reduces thrust and improves chip clearance at the cutting tip. The straight-cylindrical shank seats securely in standard 3-jaw chucks. This bit is appropriate for use in drill presses, hand drills, and CNC drilling operations by machinists, fabricators, maintenance technicians, and general tradespeople.

This drill bit is suited for production and maintenance drilling applications in light manufacturing, sheet metal work, and general fabrication. The jobber-length format offers a balanced combination of reach and rigidity, making it appropriate for through-hole and spotting operations in mild steel, aluminum, and similar workpiece materials. The right-hand spiral flute evacuates chips efficiently during standard rotary drilling.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians. Secure the shank fully in the chuck and confirm the bit runs true before engaging the workpiece. Always wear appropriate eye protection and secure the workpiece before drilling. Do not exceed the recommended RPM range for the workpiece material and bit diameter.
