Guhring 9055150107200 Carbide Drill Bit 27/64 in

Product Description

The GUHRING 9055150107200 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. Built to DIN 6537L standards, it features a 140-degree split point (SU point type) with web thinning for self-centering entry without a center punch. The FIREX coating provides thermal and wear resistance, extending tool life in demanding production environments. At 118 millimeters overall length with a 71-millimeter flute length, this is a two-flute, right-hand spiral bit suited for CNC machining centers and production drilling operations where dimensional consistency and tool longevity are priorities.

This bit is rated for cast iron and steel workpiece materials (ISO material codes K and P). The 5xD flute-to-diameter ratio and tapered web configuration support efficient chip evacuation in moderate-depth holes. The straight-cylindrical shank at 12 millimeters diameter seats securely in standard ER collet chucks and drill chucks. It is appropriate for both job shop and production floor environments where a high-performance carbide tool is specified over HSS alternatives. Coolant-through is not supported on this model.

Key Features

• Solid carbide construction with submicron-grade material for hardness and edge retention
• FIREX coating for heat and wear resistance in steel and cast iron drilling
• 140-degree SU split point with web thinning for self-centering entry
• Right-hand spiral flute with regular helix for controlled chip evacuation
• Straight-cylindrical shank compatible with standard collet and drill chuck tooling
• Conforms to DIN 6535 and DIN 6537L standards

Compatibility

Designed for use in CNC machining centers and production drilling setups targeting cast iron and steel workpieces (ISO K and P material groups) where a solid carbide jobber-length drill conforming to DIN 6537L is specified.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with carbide tooling requirements. Secure the straight-cylindrical shank fully in a concentric ER collet or precision drill chuck to within manufacturer runout tolerances before operation. Carbide tooling is brittle — avoid interrupted cuts, lateral loading, or manual hand-drill use, which can cause sudden fracture. Set spindle speed and feed rate per material-specific carbide drilling parameters before engaging the workpiece.
