Guhring 9006180047600 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180047600 is a 3/16-inch (0.1875 inches) diameter extra length cobalt drill bit designed for deep hole drilling applications. Built to DIN 1869 standards, it features a parabolic flute geometry with a web-thinned, tapered web configuration that promotes efficient chip evacuation and reduced cutting resistance. The 130-degree point angle suits a wide range of workpiece materials. With an overall length of 7.677 inches and a flute length of 5.315 inches, this bit handles drilling depths up to 5.034 inches. It is installed by machinists, tool-and-die technicians, and metalworking professionals requiring extended reach in production or maintenance environments.

This drill bit is rated for use on aluminum, titanium alloy, and steel workpieces, covering material codes K, M, N, P, S, and H. Its 15xD flute-to-diameter ratio makes it well suited for deep hole work in aerospace, automotive, and general metalworking applications where standard-length bits cannot reach. The straight-cylindrical shank with a 3/16-inch diameter and 60 mm shank length seats securely in standard drill chucks and collet holders. Right-hand cutting direction is standard.

Key Features

• Cobalt construction provides heat resistance and extended tool life in demanding materials including titanium alloy and steel
• Parabolic flute geometry with tapered, web-thinned web promotes chip evacuation in deep hole drilling
• 130-degree point angle with standard point type for broad material compatibility
• 15xD flute-to-diameter ratio enables drilling depths up to 5.034 inches (127.86 mm)
• Uncoated finish — suitable for use with cutting fluids where coating interaction is a concern
• Manufactured to DIN 1869 specification for consistent dimensional accuracy

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 3/16-inch straight-cylindrical shank. Primary workpiece materials include aluminum and titanium alloy; secondary material is steel. Conforms to DIN 1869 extra length drill bit standards.

Installation Notes

Installation and operation should be performed by qualified machinists or metalworking technicians familiar with deep hole drilling procedures. Ensure the shank is fully seated and secured in the chuck or collet before operation. Use appropriate cutting fluid or coolant compatible with the workpiece material to manage heat, particularly when drilling titanium alloy or steel. Inspect the cutting edges and web condition before each use; discard or re-sharpen if chipping or wear is observed.
