Guhring 9002050128000 Jobber Drill Bit 12.8mm Hss

Product Description

The GUHRING 9002050128000 is a jobber length drill bit designed for general-purpose drilling in metal, fabrication, and machining applications. Built from M2 high speed steel with an oxide coating for reduced friction and improved chip flow, this bit features a 118-degree standard point angle and a web-thinned, tapered web configuration for easier penetration and reduced thrust. The straight-cylindrical shank measures 12.80 mm in diameter, making it compatible with standard drill chucks. With an overall length of 151 mm and a flute length of 101 mm, this bit delivers reliable performance in a wide range of production and maintenance drilling tasks.

This drill bit suits metalworking professionals, machinists, and maintenance technicians working in industrial, commercial, and shop environments. The DIN 338 specification ensures dimensional consistency and interchangeability with tooling setups that call for metric jobber length bits. The right-hand spiral flute design efficiently evacuates chips during through-hole and blind-hole drilling operations in steel, cast iron, and similar materials.

Key Features

• M2 high speed steel construction for durability in ferrous and non-ferrous materials
• Oxide coating reduces friction and extends tool life between resharpening intervals
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank at 12.80 mm diameter fits standard drill chucks
• Conforms to DIN 338 specification for consistent metric jobber length dimensions

Compatibility

Designed as a DIN 338 metric jobber length drill bit, this tool fits standard drill chucks and drilling equipment configured for a 12.80 mm straight-cylindrical shank within the 12.50 mm to 15.00 mm drill bit size range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press, CNC, or hand-drill operation. Ensure the machine spindle is fully stopped and power is disconnected before changing tooling. Secure the shank firmly in the chuck to the full gripping depth to prevent runout or slippage during operation. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed settings based on workpiece material.
