Guhring 9003360076700 Taper Length Drill Bit 0.3020 in

Product Description

The GUHRING 9003360076700 is a cobalt taper length drill bit designed for demanding material removal in production and maintenance environments. Built to DIN 340 standards, this Series 336 bit features a 0.3020-inch diameter with a parabolic flute geometry and a 130-degree split point for fast penetration and reduced walking. The web-thinned, parallel web construction improves chip evacuation and reduces thrust, making it well-suited for extended-reach drilling in tough ferrous materials. It carries a right-hand cut, a cylindrical shank, and a bright uncoated finish. Licensed tradespeople and machining professionals use this bit where standard length drills cannot reach.

This bit is rated for use in cast iron, hardened materials, stainless steel, and steel. With a flute-to-diameter ratio of 10xD, it handles deep-hole applications where chip packing is a concern. The 4.28-inch flute length and 6.50-inch overall length allow it to reach into counterbored fixtures, deep flanges, and structural assemblies that shorter jobber-length bits cannot access. It is a practical choice for CNC drilling, manual drill press work, and handheld right-angle drilling in structural or fabrication settings.

Key Features

• Cobalt tool material for heat and wear resistance in stainless steel and hardened materials
• 130-degree point angle with web thinning reduces entry force and improves centering
• Parabolic flute design accelerates chip evacuation in deep-hole drilling
• 10xD flute-to-diameter ratio supports drilling depths up to 3.839 inches
• DIN 340 specification ensures dimensional consistency and interchangeability
• Bright uncoated finish allows easy visual inspection for wear or damage

Compatibility

Designed as an OEM-style replacement and standard production drill for applications in cast iron, hardened materials, stainless steel, and steel, conforming to DIN 340 taper length drill bit specifications.

Installation Notes

This bit is installed by machinists, tool and die workers, and maintenance mechanics using standard drill chucks or collet-style toolholders that accept a 0.3020-inch cylindrical shank. Secure workpieces firmly before drilling and confirm spindle speed and feed rate are appropriate for the workpiece material. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present. Coolant-through is not supported on this bit, so apply external cutting fluid when drilling stainless steel or hardened materials to manage heat buildup.
