Guhring 9002050018500 No 49 Hss Jobber Drill Bit

Product Description

The GUHRING 9002050018500 is a No. 49 wire-size jobber-length drill bit ground from M2 high speed steel with a bright, uncoated finish. The 118-degree standard point and spiral flute geometry deliver reliable chip evacuation during general-purpose drilling operations. At 1.85 mm (0.0728 inches) shank diameter and 46 mm (1.81 inches) overall length, with a 22 mm (0.87 inches) flute length and a maximum drilling depth of 19.23 mm (0.757 inches), this bit fits standard drill chucks and is sized for precision work in tight clearance layouts. It is manufactured to DIN 338 specification and carries a web-thinned, tapered web configuration that reduces thrust force at entry.

This jobber drill is rated for cutting cast iron and steel and is suited to production and maintenance drilling tasks in fabrication shops, machine shops, and field service settings. The straight-cylindrical shank seats in keyless or keyed drill chucks without adapters. Its 5xD flute-to-diameter ratio and regular spiral type make it a practical general-purpose choice for licensed machinists, millwrights, pipefitters, and electricians who need consistent results from a small-diameter wire-gauge bit.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a standard drill press, hand drill, or CNC spindle. Secure the straight-cylindrical shank fully in the chuck before operation and verify the workpiece is clamped to prevent movement. Use appropriate cutting fluid or lubrication when drilling steel to extend tool life. Inspect the cutting edges for wear before each use and replace when point geometry is compromised.
