Guhring 9005490090000 Jobber Drill Bit 9mm Hss

Product Description

The GUHRING 9005490090000 is a jobber length drill bit engineered for high-performance drilling in aluminum, non-ferrous metals, and similar materials. Built from high speed steel with a bright uncoated finish, this bit measures 9 mm (0.3543 inches) in diameter and carries an overall length of 4-59/64 inches (4.9219 inches). The 130-degree split point improves centering accuracy and reduces walking on entry. The web-thinned, tapered web construction lowers thrust requirements, while the parabolic flute geometry promotes efficient chip evacuation during deep-hole operations. Licensed machinists, tool-and-die workers, and maintenance technicians across manufacturing and fabrication environments rely on this style of bit for consistent, accurate results.

This drill bit is suited for use in CNC machining centers, drill presses, and hand-held power drills operating on aluminum and other K, N, and P material group workpieces as classified by cutting tool standards. The straight-cylindrical shank allows direct chuck mounting without adapters, making it compatible with standard three-jaw and keyless chucks in both benchtop and floor-model drill presses. Typical applications include hole production in structural aluminum plate, sheet metal, and light-duty steel components where parabolic flute geometry provides an advantage in chip control.

Key Features

• 9 mm (0.3543 inches) diameter with tight diameter tolerance of -0.022 to 0.000 mm for precision hole sizing
• Parabolic flute geometry with web thinning for reduced thrust and improved chip evacuation
• 130-degree point angle with standard point type for accurate entry and reduced walking
• High speed steel construction rated as high performance grade for extended tool life in target materials
• Straight-cylindrical shank compatible with standard drill chucks without adapters
• Conforms to DIN 338 specification for consistent geometry and interchangeability

Compatibility

Designed as an OEM-style jobber length drill bit conforming to DIN 338, suitable for use in any standard drill press or CNC spindle accepting a 0.3543-inch straight shank. Primary workpiece materials are aluminum and non-ferrous metals (K, N, and P material groups per cutting tool classification).

Installation Notes

This bit is installed by a machinist or maintenance technician using a standard three-jaw or keyless chuck. Always confirm the machine is powered off and the spindle is fully stopped before inserting or removing the bit. Secure the shank fully within the chuck jaws and verify concentricity before beginning a drilling cycle. Coolant-through is not supported on this bit; use external flood or mist coolant where required by the application.
