Guhring 9005150041000 Screw Machine Drill Bit 0.1614in

Product Description

The GUHRING 9005150041000 is a screw machine length (stub) drill bit designed for high-productivity drilling in demanding materials. Built from powdered metal (PMASP60 grade) and coated with FIREX finish for heat and wear resistance, this bit handles cast iron, hardened materials, stainless steel, and general steel. It features a parabolic flute geometry with web thinning for improved chip evacuation and reduced thrust force at the cutting edge. The 130-degree split point provides self-centering entry and minimizes walking on hard or interrupted surfaces. Overall length is 2.1654 inches with a straight-cylindrical shank, conforming to DIN 1897 specification for screw machine length tooling.

This drill bit is suited for production machining, tool and die, and maintenance environments where short, rigid tooling is preferred over jobber-length bits. The stub length reduces deflection and chatter in CNC machining centers, drill presses, and manual lathes. Primary workpiece materials include cast iron, stainless steel, hardened materials, and carbon and alloy steels. The FIREX coating extends tool life in abrasive and high-temperature cutting applications, making this bit a practical choice for machinists and tool room technicians running repeated hole cycles.

Key Features

• Powdered metal construction (PMASP60) for toughness in hard and abrasive workpiece materials
• FIREX coating improves heat resistance and extends cutting life
• Parabolic flute with web thinning promotes efficient chip evacuation and lower thrust
• 130-degree standard point for self-centering entry and reduced walking
• Straight-cylindrical shank fits standard drill chucks and collets without modification
• DIN 1897 screw machine length for maximum rigidity and minimal deflection

Compatibility

Designed as an OEM-style screw machine length drill bit conforming to DIN 1897, compatible with standard drill chucks and collets accepting a straight-cylindrical shank in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or tool room technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and locked out before changing or inspecting the bit. Secure the shank firmly in a properly sized chuck or collet to the manufacturer-recommended clamping depth before cutting. Do not exceed the recommended feed and speed parameters for the workpiece material and machine type.
