Guhring 9002050014400 Jobber Drill Bit 1.44mm Hss

Product Description

The GUHRING 9002050014400 is a jobber length drill bit engineered for precision drilling in metalworking applications. Built from M2 high speed steel with a bright uncoated finish, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces entry resistance and improves centering. The 1.44 mm diameter and 40 mm overall length place it in the standard jobber class, making it a go-to choice for production drilling and general-purpose hole-making. Licensed machinists, tool-and-die workers, and maintenance mechanics install this bit in standard drill chucks and CNC toolholders alike.

This drill bit is suited for general-purpose drilling in cast iron and steel workpieces. The spiral flute geometry and right-hand cut direction promote efficient chip evacuation in through-hole and blind-hole operations. Its straight-cylindrical shank with a 1.44 mm shank diameter fits directly into standard collets and Jacobs-style chucks without adapters. The 5xD flute-to-diameter ratio supports drilling depths up to 15.84 mm, appropriate for light production runs and maintenance work where small-diameter precision holes are required.

Key Features

• M2 high speed steel construction for durability across general-purpose metal drilling
• 118-degree standard point angle with web-thinned tapered web for improved self-centering
• Bright uncoated finish suited for use with cutting fluids or dry in light-duty applications
• Right-hand spiral flute promotes positive chip evacuation in ferrous materials
• Straight-cylindrical shank at 1.44 mm diameter fits standard collets and drill chucks without adapters
• Conforms to DIN 338 specification, Series 205

Compatibility

Designed as a DIN 338 compliant general-purpose jobber length drill bit for use in standard drill chucks, collets, and CNC toolholders accepting a 1.44 mm straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

This bit is installed by machinists and maintenance technicians using standard drill presses, CNC machining centers, or hand-held power drills. Ensure the chuck or collet is fully seated and torqued before operation. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling ferrous materials to extend tool life. Inspect the cutting edges for wear before each use and replace if the point shows chipping or blunting.
