Guhring 9002050054100 No. 3 Hss Jobber Drill Bit

Product Description

The GUHRING 9002050054100 is a high speed steel jobber-length drill bit sized to No. 3 wire gauge (0.2130 inches decimal equivalent). It features a 118-degree standard point angle, a two-flute right-hand spiral configuration, and an oxide coating for basic lubricity and surface protection. The straight-cylindrical shank measures 5.41 mm in diameter. Overall length is 93.00 mm (approximately 3.66 inches), with a flute length of 57.00 mm and a maximum drilling depth of 48.89 mm (approximately 1.93 inches). Manufactured to DIN 338 standards from M2 material grade high speed steel, this bit is suited for general-purpose drilling applications where consistent hole quality is required.

This drill bit is designed for general-purpose drilling in cast iron and steel workpieces. The web-thinned, tapered web design reduces thrust force at entry and improves chip evacuation during through-hole drilling. It is appropriate for use in drill presses, CNC drilling operations, and hand-held electric drills where a standard jobber-length bit is called for. The Series 205 designation places it within a recognized product family for trade and industrial procurement. Machinists, maintenance mechanics, and metalworking tradespeople are the primary users.

Compatibility

Designed as a general-purpose replacement or stock drill bit for use in standard drill chucks accepting a 0.2130-inch straight-cylindrical shank. Intended for drilling cast iron and steel workpieces as specified by the manufacturer.

Installation Notes

Installation of this drill bit is performed by machinists or maintenance trades using a standard keyed or keyless chuck rated for the shank diameter. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Verify chuck jaw seating and tighten securely before beginning any drilling operation. Use appropriate cutting fluid or coolant when drilling ferrous materials to extend tool life and maintain hole tolerance.
