Guhring 9003360016100 Taper Length Drill Bit 0.0635 in

Product Description

The GUHRING 9003360016100 is a cobalt taper length drill bit designed for demanding metal-cutting applications. It carries a 130-degree split point angle with web thinning for clean entry and reduced thrust. The parabolic flute geometry improves chip evacuation in deep-hole work, and the bright uncoated finish suits applications where lubricity coatings are unnecessary. At 3 inches overall length with a flute length of roughly 1-31/32 inches and a 10xD flute-to-diameter ratio, this drill handles deeper reach requirements beyond what a jobber-length bit provides. Licensed tradespeople and precision machinists install this bit in production and maintenance environments where tool consistency and geometry matter.

This drill bit is sized at 0.0635 inches in diameter, equivalent to a No. 52 wire gauge designation. It is intended for use in cast iron, hardened materials, stainless steel, and steel. The cylindrical shank fits standard drill chucks without modification. The right-hand cut and parabolic flute design make it well suited for CNC drilling operations and manual drill press work where hole quality and depth consistency are priorities. The Series 336 designation places it within a high-performance cobalt product family built to DIN 340 specifications.

Key Features

• Cobalt tool material provides heat resistance and edge retention in hard and abrasive metals
• 130-degree point angle with web thinning reduces walking and improves centering on entry
• Parabolic flute geometry promotes efficient chip evacuation in deeper cuts
• Taper length OAL of 3 inches extends reach beyond standard jobber-length drills
• Right-hand cut, cylindrical shank compatible with standard drill chucks
• Manufactured to DIN 340 standard for consistent geometry and tolerance

Compatibility

Designed as an OEM-style taper length drill bit suitable for use in standard drill chucks and CNC tool holders accepting a 0.0634-inch cylindrical shank. Rated for cast iron, hardened materials, stainless steel, and steel per manufacturer material application data.

Installation Notes

Installation and use should be performed by qualified machinists or tool and die tradespeople familiar with drill press, milling machine, or CNC equipment. Secure the shank fully in the chuck before operation and verify runout before drilling. Use appropriate cutting fluid or coolant for the workpiece material, particularly when drilling stainless steel or hardened stock. Do not exceed the drill manufacturer recommended feed and speed parameters for the material being machined.
