Guhring 9005150050000 Stub Drill Bit 0.1969 in Powdered Metal

Product Description

The GUHRING 9005150050000 is a screw machine length (stub) drill bit designed for high-production drilling in ferrous and cast iron applications. Built from powdered metal (PMASP60 grade) with a coated finish, this bit delivers consistent performance in demanding shop environments. It features a parabolic flute geometry and a web-thinned, parallel web configuration that promotes efficient chip evacuation and reduced thrust. The straight-cylindrical shank measures 0.1969 inches in diameter and seats securely in standard drill chucks and collets. The 130-degree point angle suits harder workpiece materials including cast iron and steel. Licensed machinists, tool-and-die shops, and industrial maintenance technicians are the primary users of this type of bit.

This drill bit is suited for stub-length drilling operations where rigidity and minimal deflection are priorities. The short overall length of 2.4409 inches reduces chatter in high-speed CNC machining centers, drill presses, and turret lathes. Primary workpiece materials are cast iron and steel. The 3xD flute-to-diameter ratio and 18.50 mm maximum drilling depth make it well matched to through-hole and blind-hole applications in moderate material thicknesses. Conformance to DIN 1897 ensures dimensional consistency across production runs.

Key Features

• Powdered metal construction (PMASP60) for extended tool life in steel and cast iron
• Parabolic flute design promotes fast chip evacuation and reduced heat buildup
• Web-thinned parallel web lowers thrust requirements and improves drill-through performance
• 130-degree split point angle reduces walking and suits harder ferrous materials
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Meets DIN 1897 specification for consistent stub-length dimensional tolerances

Compatibility

Designed as a DIN 1897 stub-length drill bit for use in standard drill chucks, collet holders, and turret lathe tooling that accept a 0.1969-inch straight-cylindrical shank. Suitable for cast iron and steel workpieces across CNC and manual drilling equipment.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools and shop safety practices. Ensure the spindle is fully stopped and machine is powered down before loading or removing the bit from the chuck or collet. Verify chuck or collet runout is within acceptable tolerance before use, as excessive runout at this diameter will accelerate premature tool wear. Follow machine manufacturer feed and speed recommendations for the workpiece material.
