Guhring 9005150060000 Screw Machine Drill Bit 0.2362 in

Product Description

The GUHRING 9005150060000 is a stub-length screw machine drill bit designed for high-productivity drilling in cast iron and steel. Built from powdered metal (PMASP60 grade) with a coated finish, this bit holds tight diameter tolerances and resists wear under continuous shop use. The 130-degree split point and web-thinned, parallel web configuration reduce entry force and improve chip evacuation. With a parabolic flute design and a flute-to-diameter ratio of 3xD, it handles chip clearing efficiently in short-hole drilling applications. Licensed trades and machining professionals working with CNC lathes, drill presses, and screw machine setups will find this bit dimensionally consistent and ready for production runs.

This drill bit is suited for stub-length drilling operations in ferrous materials including cast iron and steel. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders. At 2.5984 inches overall length with a 1.1024-inch flute length, it fits screw machine and turret lathe setups where clearance is limited. The maximum drilling depth is 0.748 inches, making it appropriate for through-holes and blind holes in sheet stock, plate, and machined castings. It conforms to DIN 1897 specification, which defines stub-length twist drill geometry and tolerances.

Key Features

• Powdered metal construction (PMASP60 grade) for hardness and wear resistance in ferrous materials
• 130-degree drill point angle with web thinning for reduced thrust and cleaner entry
• Parabolic flute geometry promotes efficient chip evacuation in short-hole drilling
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Conforms to DIN 1897 stub-length specification for consistent dimensional performance
• Diameter tolerance of +0.000 to -0.018 mm for precision fitment in close-tolerance holes

Compatibility

Designed as a DIN 1897 stub-length replacement or production drill bit for use in standard drill chucks and collet systems accepting a straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

This bit is installed by machinists and tool-and-die professionals in screw machine, turret lathe, or drill press setups. Secure the shank fully in the chuck or collet before operation and verify runout before production drilling. Always follow machine guarding and PPE requirements per shop safety standards. Coolant-through is not supported on this bit; external coolant or cutting fluid is recommended when drilling steel at extended depths.
