Guhring 9039800048260 Spiral Flute Tap 10-24 Unc

Product Description

The GUHRING 9039800048260 is a spiral flute tap designed for threading blind holes in alloyed and unalloyed steel. Part of the Series 3980 line, it cuts a 10-24 UNC right-hand thread with a modified bottoming chamfer, making it suitable for threading close to the bottom of a blind bore. The 40-degree helix angle and fast flute style help evacuate chips efficiently during the tapping operation. Finished with a TiN coating over a cobalt substrate, the tap offers improved wear resistance and performance in ferrous materials. Overall length is 2.382 inches.

This tap is intended for blind hole threading applications in alloyed and unalloyed steel workpieces. The modified bottoming chamfer allows threads to be cut nearer to the bottom of a hole than a standard plug or taper chamfer would permit. It is sized for 10-24 UNC threads, a common fastener specification found in machine components, fixtures, and assemblies across light manufacturing and maintenance environments. Machinists, tool-and-die makers, and maintenance technicians working with ferrous materials will find this tap suited to production and repair tapping operations.

Key Features

• 10-24 UNC right-hand thread, right-hand flute spiral configuration
• Modified bottoming chamfer for threading close to the bottom of blind holes
• 40-degree helix angle with fast flute style for efficient chip evacuation

Compatibility

Designed for blind hole threading in alloyed and unalloyed steel. Suited for use in CNC tapping centers, drill presses, and manual tapping applications where a 10-24 UNC H7 thread class is specified.

Installation Notes

Tapping operations should be performed by qualified machinists or maintenance technicians familiar with threading tools and speeds appropriate to cobalt taps in steel. Ensure the workpiece is securely fixtured and the spindle is properly aligned before tapping. Apply a suitable cutting fluid or tapping compound rated for steel to extend tool life and improve thread quality. Follow machine manufacturer guidelines and applicable shop safety procedures when operating tapping equipment.
