Guhring 9055190095000 Cobalt Drill Bit 9.5 Mm Tin

Product Description

The GUHRING 9055190095000 is a cobalt jobber length drill bit designed for demanding metal drilling applications. Built to DIN 338 standards, this bit measures 9.5 mm in diameter with an overall length of 125 mm and a flute length of 81 mm. The M35 cobalt steel construction is finished with a Titanium Nitride (TiN) coating to extend tool life and reduce heat buildup at the cutting edge. A four-facet split point with web thinning improves centering accuracy and reduces walking at entry. This bit is intended for use by machinists, maintenance technicians, and tool-and-die professionals who need reliable performance in production or field environments.

This drill bit suits applications in aluminum, steel, and other materials corresponding to workpiece material codes K, M, N, and P. The straight-cylindrical shank allows use in standard drill chucks and quick-change holders. With a maximum drilling depth of 66.75 mm and a regular spiral designed for efficient chip evacuation, it handles through-hole and blind-hole work in both CNC and handheld drilling setups. The 5xD flute-to-diameter ratio supports stable cutting in materials where rigidity and chip control matter.

Key Features

• M35 cobalt steel construction for high-heat and abrasive material resistance
• Titanium Nitride (TiN) coating reduces friction and extends cutting life
• Four-facet split point with web thinning for accurate, self-centering entry
• Right-hand cut with regular spiral flute for consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks and quick-change systems
• DIN 338 compliant, Series 5519

Compatibility

Designed as a jobber length drill bit for use in applications involving aluminum and ferrous metals with workpiece material codes K, M, N, and P, per DIN 338 Series 5519 specifications. Fits any drill chuck or quick-change holder accepting a 9.5 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant when drilling ferrous metals to maintain edge life, noting this bit does not support coolant-through delivery. Follow applicable workplace safety standards for rotating equipment when operating at speed.
