Guhring 9003360054100 Taper Length Drill Bit 0.2130 in

Product Description

The GUHRING 9003360054100 is a taper length twist drill bit designed for demanding metal-cutting applications in professional machine shop and industrial environments. Built from cobalt high-speed steel, this bit handles hard-to-machine materials where standard HSS tooling falls short. It carries a 130-degree split point angle with web thinning for reduced thrust and cleaner entry without center-punching. The parabolic flute geometry promotes efficient chip evacuation, especially in deeper holes. With an overall length of 5.469 inches and a flute length of 3.594 inches, this is a longer-reach bit suited for through-hole work and setups that require reach beyond a jobber-length drill.

This drill bit is rated for use in cast iron, hardened materials, stainless steel, and steel. The parabolic flute with a 10xD flute-to-diameter ratio makes it well suited for production drilling where chip packing in deep holes is a concern. The cylindrical shank at 0.2130 inches fits standard three-jaw drill chucks and collet holders without adapters. It conforms to DIN 340 specification, making it compatible with metric tooling setups and standard inch-based machining operations alike. Typical users include machinists, tool-and-die technicians, and maintenance professionals working on CNC or manual drill presses and machining centers.

Key Features

• Cobalt tool material for high-performance drilling in stainless steel, hardened materials, and cast iron
• 130-degree standard point angle with web thinning for reduced entry thrust
• Parabolic flute geometry with 10xD ratio for deep-hole chip evacuation
• Bright/uncoated finish — suitable for use with cutting fluids or dry where specified
• Cylindrical shank compatible with standard drill chucks and collet systems
• Manufactured to DIN 340 specification for consistent dimensional tolerances

Compatibility

Designed as a DIN 340 taper length drill bit in GUHRING Series 336, compatible with any standard drill chuck or collet holder accepting a 0.2130-inch cylindrical shank. Suitable for use in CNC machining centers, radial arm drills, and manual drill presses across cast iron, hardened materials, stainless steel, and carbon steel applications.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with drill press and machining center setup. Secure the cylindrical shank firmly in a properly sized collet or three-jaw chuck before operation and verify runout is within acceptable limits for the application. Always reduce spindle speed and increase feed rate relative to jobber-length bits to account for the longer reach. Apply appropriate cutting fluid for the material being drilled, especially when working stainless steel or hardened stock.
