Guhring 9005150051800 Drill Bit 0.204 in 130 Deg Pm

Product Description

The GUHRING 9005150051800 is a stub-length, screw machine drill bit designed for high-cycle production drilling in metalworking environments. Built from powdered metal with a coated finish, this bit cuts right-hand with a parabolic flute geometry that promotes fast chip evacuation and reduced heat buildup. The 130-degree point angle is suited for work on harder materials. At 2.4409 inches overall length and a 0.204-inch diameter, it fits standard straight-cylindrical shank toolholders. Licensed machinists, tool-and-die techs, and CNC operators are the typical users.

This bit is designed for drilling into cast iron and steel in production environments where stub-length tools are preferred for rigidity and reduced deflection. The 3xD flute-to-diameter ratio and parabolic flute form support efficient chip clearing in blind and through-hole applications. The web-thinned point reduces thrust force at entry, making it practical for both hand-feed and machine-feed setups. It carries a DIN 1897 designation, consistent with stub-length drill standards used in industrial tooling specifications.

Key Features

• Powdered metal construction with coated finish for extended wear life in steel and cast iron
• Parabolic fast-spiral flute for aggressive chip evacuation
• 130-degree cone relief point with web thinning to reduce entry thrust
• Straight-cylindrical shank for compatibility with standard drill chucks and collet holders
• DIN 1897 stub-length standard for added rigidity in production setups
• Diameter tolerance h8 for consistent fit in precision applications

Compatibility

Designed as a DIN 1897 stub-length replacement or production-use drill bit for operations involving cast iron and steel workpieces requiring a 0.204-inch diameter hole.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Ensure the drilling machine is fully powered down and at rest before changing bits. Follow shop safety procedures and applicable OSHA machine guarding requirements when operating drill presses or CNC equipment.
