Guhring 9005150026400 Stub Drill Bit 0.104 in Powdered Metal

Product Description

The GUHRING 9005150026400 is a stub-length (screw machine length) twist drill bit designed for precision drilling in ferrous materials. Built from powdered metal with a coated finish, this bit features a parabolic flute geometry and a 130-degree point angle with cone relief and web thinning. The straight-cylindrical shank fits standard drill chucks without modification. With an overall length of 1.6929 inches and a flute length of 0.5512 inches, this compact bit suits applications where rigidity and minimal deflection matter. It carries a DIN 1897 designation and is manufactured to h8 diameter tolerance, making it a reliable choice for production drilling in machine shop and automated tooling environments.

This drill bit is intended for use in cast iron and steel workpieces in both production machining and maintenance repair operations. The stub length body reduces overhang and increases stiffness compared to jobber-length bits, making it well suited for CNC drilling, screw machines, drill presses, and tapping operations where hole location accuracy is critical. The parabolic flute design promotes faster chip evacuation, reducing heat buildup during repeated-cycle drilling. Maximum drilling depth is 0.3950 inches, appropriate for shallow-to-moderate depth holes in the target materials.

Key Features

• Powdered metal construction with coated finish for improved wear resistance in ferrous materials
• 130-degree point angle with cone relief and web thinning for easier entry and reduced thrust
• Parabolic flute profile promotes efficient chip evacuation in cast iron and steel
• Stub length body increases rigidity and reduces deflection versus jobber-length bits
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Manufactured to DIN 1897 standard with h8 diameter tolerance for consistent, repeatable hole sizing

Compatibility

Designed as a DIN 1897 stub-length drill bit in the GUHRING Series 515, suited for use in cast iron and steel workpieces. Compatible with standard drill chucks accepting a straight-cylindrical shank in the 0.1000 to 0.1500 inch diameter range.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tool-and-die professional. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the shank fully within the chuck or collet to the recommended grip depth before operation. Coolant-through is not supported on this bit; apply external cutting fluid as appropriate for the workpiece material when operating at sustained duty cycles.
