Guhring 9006180054000 Cobalt Extra Length Drill Bit

Product Description

The GUHRING 9006180054000 is a cobalt extra length drill bit engineered for deep hole drilling in demanding production and maintenance environments. Built to DIN 1869 standards, this Series 618 bit features a 0.2126-inch diameter, a 130-degree drill point angle, and a parabolic flute design that efficiently clears chips during extended-reach operations. The overall length is 8.071 inches with a flute length of 5.512 inches, supporting a maximum drilling depth of 5.193 inches. Right-hand cutting, web-thinned with a tapered web configuration, and left with an uncoated finish, this bit is suited for HVAC fabricators, pipefitters, machinists, and maintenance technicians who require precision boring through thick or stacked materials.

This bit is designed for deep hole drilling applications where standard-length bits cannot reach. Primary workpiece materials include aluminum and titanium alloy, with secondary suitability for steel. The 15xD flute-to-diameter ratio and parabolic geometry support consistent chip evacuation across long cut depths, making this bit a reliable choice in high-cycle production setups or structural fabrication work where hole depth and dimensional accuracy are both critical.

Key Features

• Cobalt tool material for elevated heat resistance compared to standard HSS
• Parabolic flute geometry promotes efficient chip evacuation in deep hole drilling
• 130-degree drill point angle with web thinning reduces entry force and improves centering
• 8.071-inch overall length with 5.512-inch flute length supports up to 5.193-inch drilling depth
• Straight-cylindrical shank for use in standard drill chucks and collet holders
• Meets DIN 1869 specification for extra length drill bit geometry

Compatibility

Designed as a DIN 1869 Series 618 extra length drill bit suitable for aluminum, titanium alloy, and steel workpieces. Compatible with standard drill chucks and collet holders accepting a 0.2126-inch straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with proper drill press, CNC, or handheld drilling equipment. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Always power down and lock out the machine before changing bits. Observe applicable shop safety standards and California Proposition 65 handling precautions noted on product labeling.
