Guhring 9055140045000 Carbide Drill Bit 0.177in Series 5514

Product Description

The GUHRING 9055140045000 is a solid carbide, screw machine length drill bit engineered for high-performance drilling in demanding shop and field applications. Sized at 0.177 inches (wire size No. 16) in diameter, this bit features a 140-degree split point (SU point type) with web thinning for fast, accurate starts with minimal walking. The two-flute, regular spiral design promotes efficient chip evacuation. Built to DIN 6537K specification from submicron carbide, it is designed for machinists, tool room technicians, and CNC operators working on precision drilling tasks.

This drill bit is suited for right-hand cutting operations in cast iron and steel workpieces. The screw machine length (stub) format provides added rigidity compared to jobber-length bits, making it well matched for close-tolerance hole-making on lathes, drill presses, and CNC machining centers. The straight-cylindrical shank with a 6.00 mm diameter seats cleanly in standard drill chucks and collet holders. With a flute-to-diameter ratio of 3xD and a maximum drilling depth of 0.679 inches (17.25 mm), it handles the typical depth requirements of production and repair work in metal fabrication environments.

Key Features

• Submicron solid carbide construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning for self-centering entry and reduced thrust
• Two-flute regular spiral with parallel web for consistent chip flow
• DIN 6537K specification ensures dimensional conformance and interchangeability
• Screw machine (stub) length improves rigidity and reduces deflection in precision applications
• Coated finish for added surface hardness and wear resistance

Compatibility

Designed as an OEM-specification replacement or direct-use drill bit for standard drill chucks and collet systems accepting a 6.00 mm straight-cylindrical shank, compatible with primary workpiece materials including cast iron and steel as specified by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with proper chuck clamping procedures and appropriate feed and speed selection for carbide tooling. Always power down and lock out the machine spindle before changing tooling. Carbide bits are brittle and should not be subjected to side loads or used in hand-held drilling operations. Refer to the machine manufacturer and applicable shop safety standards when setting up drilling operations.
