Guhring 9002050004500 Jobber Drill Bit 0.45 Mm Hss

Product Description

The GUHRING 9002050004500 is a high speed steel jobber-length drill bit designed for precision drilling in metalworking applications. Built to DIN 338 standards, it features a 0.45 mm diameter, a standard 118-degree point angle, and a bright uncoated finish. The two-flute spiral design with a regular helix and web-thinned, tapered web configuration promotes efficient chip evacuation and reduced entry force. The straight-cylindrical shank provides consistent runout in standard drill chucks. This is a general-purpose tool suited for production and maintenance work where small-diameter accuracy is required.

This drill bit is sized for fine-detail and small-bore work in cast iron and steel. At 0.45 mm in diameter and 20 mm overall length, it fits applications where standard jobber-length drills are needed at the sub-millimeter scale. Typical use cases include precision component manufacturing, electronics assembly fixtures, tool and die work, and general metalworking operations. The 5xD flute-to-diameter ratio supports drilling to a maximum depth of 4.33 mm without coolant-through capability.

Key Features

• 0.45 mm drill diameter with a tolerance of +0.000 to -0.010 mm for tight-tolerance bore work
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust force
• M2 high speed steel construction for durability across cast iron and steel workpieces
• DIN 338 specification compliance ensures consistent dimensional standards
• Bright uncoated finish suitable for general-purpose metal drilling without coating degradation concerns
• Right-hand cutting, regular spiral, two-flute design for predictable chip flow

Compatibility

Designed as a general-purpose jobber drill for use in cast iron and steel workpieces, conforming to DIN 338 standards and fitting any standard drill chuck or collet accepting a 0.45 mm straight-cylindrical shank.

Installation Notes

This drill bit is installed and operated by machinists, tool and die makers, or trained technicians using a drill press, CNC machining center, or precision hand drill. Secure the straight-cylindrical shank firmly in a compatible chuck or collet before operation. At sub-millimeter diameters, excessive feed rate or lateral force will cause breakage; follow machine manufacturer feed and speed recommendations for M2 HSS at the workpiece material. Inspect the drill point for wear or chipping before each use.
