Guhring 9002050127000 1/2 Inch Hss Jobber Drill Bit

Product Description

The GUHRING 9002050127000 is a jobber length twist drill bit designed for general-purpose drilling in metal fabrication and machining applications. Built from M2 high speed steel with an oxide finish, it delivers reliable performance in cast iron and steel workpieces. The bit features a 118-degree standard point angle, a web-thinned tip for reduced thrust and easier entry, and a right-hand spiral flute with a tapered web configuration. With an overall length of 151 mm (approximately 5.94 inches) and a flute length of 101 mm (approximately 3.98 inches), it fits standard drill chucks and drill press setups used daily by machinists and maintenance professionals.

This bit is suited for production and maintenance drilling in ferrous metals, specifically cast iron and steel. The straight-cylindrical shank accepts standard three-jaw chucks on bench drills, drill presses, and hand-held power drills. It carries a DIN 338 designation, making it a recognized standard in industrial tooling across manufacturing and MRO environments. The 5xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth holes without regrinding in most common applications.

Compatibility

Designed as a DIN 338-compliant jobber length drill bit for use in cast iron and steel workpieces. Primary workpiece material codes K and P apply per standard classification. Compatible with any standard chuck accepting a 1/2 inch straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with drilling operations. Always secure the workpiece and ensure the drill press or driver is powered down before changing bits. Verify chuck jaw condition and confirm the shank is fully seated before operation. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling steel to manage heat buildup.
