Guhring 9055190045700 Cobalt Jobber Drill No 15 Tin

Product Description

The GUHRING 9055190045700 is a cobalt jobber-length drill bit designed for high-performance drilling in a wide range of materials. Built to DIN 338 standards and classified under material grade M35, this bit carries a Titanium Nitride (TiN) coating that extends tool life and reduces friction at the cutting edge. It features a 118-degree, 4-facet point with web thinning for improved centering and reduced thrust on entry. The straight cylindrical shank measures 4.57 millimeters in diameter and the overall length is 80 millimeters, making it a standard jobber-length profile suited for use in drill presses, hand drills, and CNC drilling applications.

This drill bit is sized to wire gauge No. 15, with a decimal inch equivalent of 0.1800 inches. It is listed with a primary workpiece material designation covering aluminum, cast iron, non-ferrous metals, and steel (material codes K, M, N, and P), making it a versatile general-purpose choice. The right-hand, regular spiral flute geometry supports efficient chip evacuation in most shop and field drilling scenarios. With a maximum drilling depth of 40.15 millimeters (1.581 inches) and a flute length of 47 millimeters, it is well suited to through-hole and moderate-depth drilling tasks across manufacturing, maintenance, and fabrication environments.

Key Features

• M35 cobalt steel construction for elevated heat and wear resistance compared to standard HSS bits
• TiN coating reduces friction and extends cutting tool service life
• 118-degree 4-facet point with web thinning for accurate starting and reduced thrust
• Conforms to DIN 338 standard for jobber-length drill geometry
• Right-hand regular spiral flute design promotes consistent chip evacuation
• Straight cylindrical shank for broad chuck compatibility

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard three-jaw chucks and collet systems accepting a 4.57-millimeter straight shank, suitable for drill presses, hand drills, and CNC drilling setups.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with proper tooling speeds and feeds for the workpiece material. Secure the shank fully in the chuck and verify concentricity before operation. Always wear appropriate eye protection and follow applicable shop safety protocols when drilling metal. Do not exceed the rated maximum drilling depth of 40.15 millimeters in a single pass without clearing chips.
