Guhring 9006180055600 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180055600 is a Series 618 extra length cobalt drill bit engineered for deep hole drilling applications where standard-length bits cannot reach. Built from high-performance cobalt steel and left uncoated, this bit measures 0.2188 inches in diameter with an 8.071-inch overall length and a 5.512-inch parabolic flute. The 130-degree split point and web-thinned, tapered web design reduce entry force and improve chip evacuation in difficult materials. Maximum drilling depth reaches 5.183 inches. Machinists and tool-and-die shops working with aluminum, titanium alloys, and steel rely on this bit for precision deep-hole work in manual and CNC setups.

The 9006180055600 is suited for production and job-shop environments where extended reach is required in aerospace, automotive, and general metalworking applications. Primary workpiece materials include aluminum and titanium alloys, with steel as a secondary application. The straight-cylindrical shank at 7/32-inch diameter seats securely in standard drill chucks and collet holders. Right-hand cutting direction is standard. The 15xD flute-to-diameter ratio makes this bit a direct fit for deep-hole work that demands consistent chip clearing across long flute runs.

Key Features

• Cobalt high-performance tool steel for elevated heat and wear resistance
• Parabolic flute geometry promotes efficient chip evacuation in deep holes
• 130-degree standard point angle reduces walking and entry burr
• Web-thinned, tapered web lowers thrust requirements at the cutting tip
• 15xD flute-to-diameter ratio supports deep-hole drilling up to 5.183 inches
• Conforms to DIN 1869 specification for consistent geometry and tolerancing

Compatibility

Designed as an OEM-specification replacement and standard production bit for deep hole drilling in aluminum, titanium alloy, and steel workpieces per DIN 1869; fits any standard drill chuck or collet accepting a 7/32-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with drill press, lathe, or CNC machining center operation. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout before drilling. Power down and de-energize the machine spindle before changing or inspecting the bit. Do not exceed the rated maximum drilling depth of 5.183 inches, and use appropriate cutting fluid or coolant for the workpiece material even though coolant-through is not available on this tool.
