Guhring 9002050008800 Jobber Drill 0.88mm Hss

Product Description

The GUHRING 9002050008800 is a high speed steel jobber-length drill bit ground to DIN 338 standards. It carries a 0.88 mm diameter, a standard 118-degree split point produced with web thinning, and a bright uncoated finish. The M2 HSS construction delivers the hardness and wear resistance required for general-purpose drilling in production and maintenance environments. With an overall length of 32.00 mm and a straight-cylindrical shank, this bit seats securely in standard keyless or keyed drill chucks. It is sized and ground for use by machinists, tool-and-die technicians, and maintenance professionals working with precision small-diameter applications.

This drill bit is suited for drilling cast iron and steel in both manual and CNC-assisted operations. The 5xD flute-to-diameter ratio and regular spiral geometry provide controlled chip evacuation at the small 0.88 mm working diameter. The right-hand cutting direction is compatible with standard rotating spindles. Typical applications include pilot holes, through-holes in thin stock, and precision layout work where a tight diameter tolerance is required. The DIN 338 specification makes this a recognized standard in metric tooling programs across general metalworking shops.

Key Features

• M2 high speed steel construction for general-purpose ferrous drilling
• 118-degree standard point with web thinning for easier entry and reduced walking
• Bright uncoated finish suitable for use with or without cutting fluid
• DIN 338 specification ensures dimensional conformance in metric tooling systems
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Two-flute regular spiral geometry supports chip clearance at small diameters

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks and collets sized for a 0.88 mm straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

A licensed machinist or qualified maintenance technician should verify chuck or collet concentricity before seating small-diameter tooling to prevent deflection and breakage. Secure the workpiece firmly before drilling and apply cutting fluid appropriate to the workpiece material when drilling steel. Inspect the cutting edges for wear before each use, as small-diameter HSS bits are susceptible to breakage if run at incorrect speeds or feeds.
