Guhring 9005150024900 Stub Drill Bit 0.098 in Wire 40

Product Description

The GUHRING 9005150024900 is a screw machine length (stub) drill bit designed for precision drilling in metalworking applications. Built from powdered metal with a coated finish, this bit measures 0.098 inches (wire size 40) in diameter with an overall length of 1.6929 inches and a flute length of 0.5512 inches. The 130-degree drill point angle and parabolic flute geometry promote fast chip evacuation and reduced thrust in tough materials. A straight-cylindrical shank and web-thinned point complete the design. This bit is installed by machinists, tool-and-die professionals, and CNC operators working with ferrous and non-ferrous stock.

This drill bit is suited for short-reach, high-accuracy drilling operations in production and job-shop environments. Its stub-length body reduces deflection in drilling fixtures, turrets, and screw machine setups. Primary workpiece materials include cast iron and steel. The right-hand cut and fast-spiral parabolic flute configuration make it particularly effective in applications where chip packing and heat buildup are concerns. It conforms to DIN 1897 standards and carries a Series 515 designation from GUHRING, reflecting a standardized stub-length geometry familiar to European and domestic tooling programs.

Key Features

• Powdered metal construction with coated finish for extended tool life in cast iron and steel
• Parabolic flute design with fast spiral promotes aggressive chip evacuation
• Web-thinned point reduces entry thrust and improves hole location accuracy
• 130-degree drill point angle suited for harder ferrous materials
• Stub (screw machine) length body minimizes deflection in close-tolerance setups
• Conforms to DIN 1897 standard with h8 diameter tolerance

Compatibility

Designed as a DIN 1897-compliant stub-length drill bit for use in screw machines, CNC lathes, drill presses, and machining centers where a straight-cylindrical shank and short flute length are required for cast iron and steel workpieces.

Installation Notes

This drill bit is installed by machinists and CNC technicians. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the shank diameter before operation. Follow applicable machine tool safety standards and the workpiece material guidelines specified by the tooling manufacturer.
