Guhring 9057230060040 Spiral Point Tap M6x0.75 Cobalt

Product Description

The GUHRING 9057230060040 is an M6x0.75 metric fine spiral point tap designed for through-hole threading in steel. Manufactured from HSS-E cobalt steel with a steam oxide finish, it delivers improved wear resistance and heat tolerance compared to standard HSS taps. The plug chamfer and 3-flute spiral point geometry push chips forward ahead of the cut, making this tap well-suited for production environments where clean chip evacuation matters. Overall length is 3.1496 inches with a thread length of 0.5118 inches. The D4 thread limit and 6H class of fit meet standard metric fine tolerance requirements.

This tap is intended for right-hand through-hole threading in steel workpieces requiring M6x0.75 metric fine threads. The spiral point style drives chips forward through the hole rather than packing them in the flutes, which reduces the risk of tap breakage in production runs. It is commonly used in machining, fabrication, and maintenance repair operations where metric fine thread engagement is specified. The 4.50 mm shank diameter and 3.40 mm square size fit standard tap holders and T-handle wrenches used in both manual and machine tapping setups.

Key Features

• HSS-E cobalt construction for improved heat and wear resistance in steel applications
• Steam oxide finish reduces friction and provides baseline corrosion resistance
• Spiral point geometry pushes chips forward for clean through-hole threading
• Plug chamfer provides gradual thread engagement and controlled cutting action
• D4 thread limit with 6H class of fit for standard metric fine tolerance
• Right-hand cut, no coolant-through, non-interrupted thread design

Compatibility

Designed for through-hole threading in steel at M6x0.75 metric fine specification. Part of GUHRING Series 5723.

Installation Notes

This tap is installed by machinists and metalworking professionals using standard tap holders, T-handle wrenches, or CNC tapping attachments. Always ensure the workpiece is securely fixtured and the pilot hole diameter matches the recommended drill size for M6x0.75 before tapping. Apply cutting fluid appropriate for steel to extend tap life and improve thread quality. Inspect the tap for wear or chipping before each use — a worn tap increases the risk of breakage and out-of-tolerance threads.
