Guhring 9002050004800 Jobber Drill 0.48mm Hss

Product Description

The GUHRING 9002050004800 is a high speed steel (HSS) jobber-length twist drill bit designed for precise small-diameter drilling in metalworking applications. Built to DIN 338 standards, this bit measures 0.48 mm (0.0189 decimal inch) in diameter with a 118-degree standard point angle. The bright, uncoated M2 HSS construction delivers reliable performance across general-purpose drilling tasks. At 20.00 mm overall length with a 5.00 mm flute length, this is a compact, short-series drill suited for close-tolerance work in production or repair environments. Two spiral flutes with a regular helix provide efficient chip evacuation during cutting.

This drill bit is used in applications involving cast iron and steel workpieces where small-diameter, precise hole generation is required. The straight-cylindrical shank seats securely in standard drill chucks and collets on benchtop drill presses, CNC machining centers, and hand-held power tools. Its DIN 338 Series 205 designation places it in a well-recognized size standard common in industrial maintenance, fabrication shops, and precision machining environments. Maximum drilling depth is 4.28 mm, making it appropriate for shallow through-holes and spotting operations in thin stock.

Key Features

• 0.48 mm diameter with tight tolerance of +0.000 to -0.010 mm for accurate hole sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust on entry
• M2 high speed steel construction for durability across general-purpose metal drilling
• Bright, uncoated finish suitable for use with or without cutting fluid
• Right-hand cutting direction with regular spiral flute for consistent chip removal
• Conforms to DIN 338 standard, Series 205

Compatibility

Designed as a DIN 338-compliant general-purpose jobber drill for use in straight-shank drill chucks and collets. Rated for primary workpiece materials of cast iron and steel.

Installation Notes

This drill bit is installed and operated by machinists, tool and die makers, and maintenance technicians. Secure the straight-cylindrical shank fully in a precision drill chuck or collet before operation. Due to the sub-millimeter diameter, use appropriate low-speed, high-precision spindle settings to avoid bit deflection or breakage. Inspect the cutting edges before each use; at this diameter, even minor damage to the tip will affect hole accuracy.
