Guhring 9055230050000 Cobalt Drill Bit 5 Mm 118 Deg

Product Description

The GUHRING 9055230050000 is a cobalt (M35 grade) jobber length drill bit designed for high-performance drilling in a wide range of materials. Built to DIN 338 standards, it features a 118-degree four facet split point with web thinning for fast, accurate starts and reduced thrust. The straight-cylindrical shank measures 5 mm in diameter, and the overall length comes in at 86 mm (approximately 3.39 inches). With a regular spiral flute and right-hand cut geometry, this bit handles aluminum, steel, cast iron, and non-ferrous metals efficiently. The bright, uncoated finish is standard for M35 cobalt tooling intended for general-purpose and production drilling applications.

This drill bit is suited for use in CNC machining centers, drill presses, and handheld power tools where a 5 mm hole diameter is required. It carries a workpiece material classification of K, M, N, and P, covering cast materials, steel, non-ferrous metals, and aluminum. The flute-by-diameter ratio is 5xD, with a maximum drilling depth of 44.50 mm (approximately 1.752 inches). Machinists, tool-and-die makers, and maintenance technicians working in metalworking shops or on the production floor will find this bit appropriate for light-to-medium drilling tasks.

Key Features

• M35 cobalt construction provides heat resistance for drilling steel and hard alloys
• 118-degree four facet split point with web thinning reduces walking and lowers thrust force
• DIN 338 specification ensures dimensional consistency and interchangeability
• Right-hand spiral flute with tapered web configuration for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• Bright uncoated finish allows easy visual wear inspection during service

Compatibility

Designed as an OEM-style replacement or standard production drill bit for any application requiring a 5 mm jobber length drill conforming to DIN 338. Compatible with workpiece material classifications K, M, N, and P as defined in the Series 5523 product family.

Installation Notes

Installation and use should be performed by qualified machinists or trained tradespeople familiar with rotating cutting tools. Secure the shank fully in a drill chuck or collet before operation and verify runout before drilling. Always power down and isolate the machine before changing tooling. Follow shop safety procedures and applicable OSHA standards for rotating machinery when operating drill presses or CNC equipment.
