Guhring 9006530175000 Screw Machine Drill Bit 17.5mm

Product Description

The GUHRING 9006530175000 is a stub-length screw machine drill bit designed for high-throughput drilling in cast iron and steel. Built from M2 high speed steel with a coated finish, this two-flute bit delivers consistent performance in production and job-shop environments. The 118-degree cone relief point gives clean entry on ferrous materials without requiring a center punch on most setups. With an overall length of 123 millimeters and a straight-cylindrical shank of 17.5 millimeters diameter, it mounts directly into standard drill chucks and machine tool holders. The shorter stub length provides added rigidity compared to jobber-length bits, reducing deflection in harder materials.

This drill bit is suited for CNC machining centers, drill presses, and screw machine operations where controlled depth and hole accuracy matter. Its primary workpiece materials are cast iron and steel, making it a practical choice for general metalworking, tool rooms, and production floor applications. The web-thinned geometry reduces thrust requirements at entry, which is useful when drilling deeper holes in tougher alloys. Machinists, tooling engineers, and production technicians are the typical end users for this product.

Key Features

• M2 high speed steel construction with coated finish for extended tool life on ferrous materials
• 118-degree cone relief point angle for clean entry into cast iron and steel
• Web-thinned geometry reduces thrust load and improves chip evacuation
• Stub length (series 653) provides higher rigidity and reduced deflection versus jobber-length bits
• Straight-cylindrical shank fits standard chucks and collet holders without adapter
• Manufactured to DIN 1897 standard with h8 diameter tolerance for precision fitment

Compatibility

Designed as a DIN 1897 stub-length replacement drill bit for use in standard straight-shank drill chucks and collet holders accommodating a 17.5 millimeter shank diameter.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and locked out per applicable machine safety procedures. Ensure the chuck or collet is clean and free of debris before seating the shank to maintain concentricity. Do not exceed the rated drilling depth of 35.75 millimeters for this stub-length geometry. Secure coolant-through capability is not supported on this bit, so external cutting fluid application is recommended when drilling harder steel grades.
