Guhring 9006180031700 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180031700 is a cobalt, uncoated extra length drill bit engineered for deep hole drilling applications. Built to DIN 1869 standards, it features a 130-degree drill point angle and a parabolic flute geometry that promotes efficient chip evacuation in deep bores. The bit measures 0.125 inches in diameter with a 4.134-inch flute length and a 6.102-inch overall length, giving it a 15xD flute-to-diameter ratio suitable for holes up to 3.947 inches deep. The web-thinned, tapered web design reduces thrust force at entry. This bit is intended for use by machinists and tool-and-die professionals working with precision drilling equipment.

This drill bit is rated as a high-performance tool for deep hole drilling in aluminum, titanium alloy, and steel. It is well-suited to production machining environments where standard-length bits cannot reach required depths without repositioning. The straight-cylindrical shank at 0.125 inches (1/8 inch) fits standard drill chucks and collet systems. The Series 618 designation places it within a GUHRING line designed for demanding material removal in both ferrous and non-ferrous applications.

Key Features

• Cobalt tool material provides heat resistance for drilling steel and titanium alloy
• Parabolic flute geometry improves chip flow in deep hole applications
• Web-thinned, tapered web reduces entry thrust force
• 130-degree drill point angle for accurate starting and reduced walking
• 15xD flute-to-diameter ratio supports drilling up to 3.947 inches deep
• DIN 1869 specification for consistent dimensional accuracy

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 1/8-inch straight-cylindrical shank. Primary workpiece materials include aluminum and titanium alloy; secondary workpiece material is steel.

Installation Notes

This bit should be installed by a qualified machinist following standard toolroom practices. Secure the shank fully in a collet or drill chuck before operation, and verify runout before engaging the cut. Recommended for use with a drill press, CNC machining center, or similar rigid drilling setup. No coolant-through capability is present; external coolant or cutting fluid should be applied where required by the workpiece material.
