Guhring 9005490054000 Jobber Drill Bit 5.4 Mm Hss

Product Description

The GUHRING 9005490054000 is a jobber length drill bit designed for general-purpose drilling in metal fabrication, maintenance, and light industrial applications. Manufactured from high speed steel with a bright, uncoated finish, this bit measures 5.4 mm in diameter (0.2126 inches) with an overall length of 93 mm (3.661 inches). The parabolic flute geometry promotes efficient chip evacuation and reduces heat buildup during cutting. A web-thinned, tapered web configuration reduces entry resistance at the drill point. The 130-degree split point angle suits the primary workpiece materials for which this bit is rated. This bit is installed and used by machinists, maintenance technicians, and fabricators working with aluminum, non-ferrous metals, and plastics.

This drill bit is rated primarily for aluminum and non-ferrous materials (material codes K, N, and P), making it well suited for production drilling, fixture work, and general shop use where clean entry and efficient chip flow are priorities. The straight-cylindrical shank fits standard drill chucks without adapters. It conforms to DIN 338 specifications, ensuring dimensional consistency expected in precision trade environments. The Series 549 designation identifies it within the GUHRING high performance jobber drill family. Package quantity is 1 piece per unit.

Installation Notes

This bit is installed by machinists and maintenance technicians in standard drill chucks, drill presses, or CNC drilling machines. Ensure the chuck and spindle are fully stopped before inserting or removing the bit. Secure the shank fully in the chuck to the recommended grip depth to prevent slippage during operation. Observe applicable shop safety standards and machine manufacturer guidelines for speed and feed settings when drilling the target material.
