Guhring 9002050009800 Jobber Drill Bit 0.98 Mm Hss

Product Description

The GUHRING 9002050009800 is a high speed steel jobber drill bit designed for general-purpose drilling in metalworking applications. Built to DIN 338 standards, this two-flute, right-hand spiral drill features a 118-degree standard point angle and a web-thinned, tapered web configuration that supports clean entry and reduced thrust force. The M2 HSS construction provides the hardness and wear resistance needed for repeated use in production and maintenance environments. At 0.98 mm in diameter with a bright, uncoated finish, it is suited for precise small-diameter hole work in steel and cast iron.

This drill bit is appropriate for use in machine shops, maintenance facilities, and manufacturing environments where small-diameter precision holes are required. It fits standard drill chucks and CNC machining centers capable of holding a 0.98 mm straight-cylindrical shank. Typical applications include pilot holes, through-holes in sheet metal, and light drilling in cast iron and ferrous steel workpieces. It is well-suited for machinists, tool-and-die technicians, and general metalworking trades.

Key Features

• M2 high speed steel construction for hardness and wear resistance in ferrous metals
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Right-hand spiral flute, regular helix for efficient chip evacuation
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy at small diameters
• Meets DIN 338 specification for jobber-length drill geometry
• Straight-cylindrical shank compatible with standard collets and drill chucks

Compatibility

Designed as an OEM-style jobber drill conforming to DIN 338 for use in any standard drill chuck or collet accepting a 0.98 mm straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or metalworking technicians familiar with small-diameter tooling. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits, as deflection at sub-1 mm diameters can cause breakage. Power down the machine and lock out energy sources before changing tooling. Do not exceed the recommended maximum drilling depth of 10.53 mm for this diameter without retracting to clear chips.
