Guhring 9006180043000 Cobalt Extra Length Drill Bit

Product Description

The GUHRING 9006180043000 is a cobalt extra length drill bit designed for deep hole drilling applications in demanding production and maintenance environments. Built to DIN 1869 standards, this uncoated bit measures 0.1695 inches in diameter with a 7.283 inch overall length and a 4.921 inch flute length, delivering a reach-to-diameter ratio of 15xD. The parabolic flute geometry promotes efficient chip evacuation during extended cuts, while the web-thinned, tapered web reduces thrust requirements at the point. Licensed machinists, tool-and-die makers, and production drilling operators are the primary users of this bit.

This bit is suited for deep hole drilling in aluminum, titanium alloy, and steel workpieces across aerospace, general machining, and fabrication settings. The straight-cylindrical shank seats directly in standard drill chucks or collet holders without modification. At wire gauge size 18 (4.31 mm), it fits tooling setups where precise hole diameter and depth are critical. The right-hand cutting direction and standard point geometry make it compatible with conventional CNC and manual drilling operations.

Key Features

• DIN 1869 extra length series 618 construction for deep hole drilling
• Parabolic flute design improves chip flow and reduces heat buildup in deep bores
• Web-thinned, tapered web lowers entry thrust and improves centering
• 130-degree drill point angle suits aluminum, titanium alloy, and steel workpieces
• Straight-cylindrical shank fits standard chucks and collet systems without modification
• Uncoated cobalt construction provides heat resistance without coating adhesion concerns on abrasive alloys

Compatibility

Designed as a DIN 1869 Series 618 extra length drill bit for use in standard drill chucks and collet holders accepting a 0.1693 inch straight-cylindrical shank; primary workpiece materials are aluminum and titanium alloy with secondary suitability for steel.

Installation Notes

Installation and use should be performed by qualified machinists familiar with drilling parameters for cobalt tooling. Secure the workpiece and verify chuck or collet runout before beginning any deep hole operation. Ensure adequate chip clearing and lubrication or coolant flow appropriate to the workpiece material, even though this bit does not support through-coolant. Comply with applicable shop safety standards and machine manufacturer guidelines when operating at extended lengths.
