Guhring 9005150055000 Stub Drill Bit 0.2165 in 130 Deg

Product Description

The GUHRING 9005150055000 is a stub-length (screw machine length) powdered metal drill bit designed for high-productivity drilling in ferrous materials. Built to DIN 1897 standards, it features a 130-degree split point with web thinning for reduced thrust and a parabolic flute geometry that promotes efficient chip evacuation at elevated feed rates. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. At 0.2165 inches in diameter and 2.5984 inches overall length, this bit is suited for tight-clearance setups where a jobber-length drill would be impractical. The PMASP60 powdered metal substrate provides wear resistance for extended tool life in production environments.

This drill bit is intended for use in ferrous applications including cast iron and steel. The stub-length body reduces deflection, making it a reliable choice for CNC machining centers, drill presses, and screw machine operations where rigidity and repeatable hole quality are required. The parabolic flute profile and web-thinned point work together to lower cutting forces, which is particularly useful when drilling into harder steel grades or when working with shorter workpiece setups requiring improved chip clearance.

Key Features

• 0.2165 inch diameter with a diameter tolerance of +0.000 to -0.018 mm for consistent hole sizing
• 130-degree drill point angle with web thinning for reduced entry force and self-centering action
• Parabolic 2-flute design promotes fast chip evacuation in deep and blind-hole applications
• Stub (screw machine) length body minimizes deflection in tight setups and short-reach applications
• Powdered metal (PMASP60) construction rated for cast iron and steel workpiece materials
• Conforms to DIN 1897 specification for dimensional consistency across replacement bits

Compatibility

Designed as a DIN 1897 stub-length replacement drill bit for use in standard straight-shank drill chucks and collet holders rated for 0.2165 inch diameter tooling. Primary workpiece materials are cast iron and steel as specified by the manufacturer.

Installation Notes

This drill bit should be installed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the straight-cylindrical shank fully into the chuck or collet and confirm runout with a dial indicator before cutting. Coolant-through is not supported on this bit; apply external cutting fluid or mist coolant appropriate for the workpiece material when required.
