Guhring 9039140048260 Spiral Point Tap 10-32 Unf

Product Description

The GUHRING 9039140048260 is a spiral point tap designed for cutting 10-32 UNF internal threads in through-hole applications. Built from HSS-E cobalt high-speed steel with a bright, uncoated finish, it delivers reliable performance in steel and similar ferrous materials. The plug chamfer allows progressive thread engagement, and the spiral point geometry pushes chips forward through the hole rather than packing them in the flutes. Overall length is 2.382 inches, thread length is 0.551 inches, and shank diameter is 0.194 inches. Licensed machinists and maintenance technicians install this tap in manual tap handles or machine tapping setups where right-hand threading is required.

This tap is suited for through-hole threading in steel workpieces requiring a 10-32 UNF thread form with a 2B class of fit. The 2B class of fit is the standard tolerance range for general-purpose inch fastener threads, making this tap appropriate for production runs, repair work, and maintenance threading in industrial, mechanical, and trade-service environments. The H3/H4 thread limit designation indicates a slightly oversized tap geometry to compensate for springback in tougher materials. It is sold individually and is appropriate wherever a Series 3914 spiral point tap in this size is specified.

Key Features

• HSS-E cobalt construction for improved wear resistance in steel applications
• Spiral point geometry pushes chips forward, reducing chip packing in through-hole work
• Plug chamfer provides progressive thread engagement and easier starting
• 2B class of fit meets standard general-purpose UNF thread tolerance requirements
• H3/H4 thread limit accommodates material springback in harder steels
• Bright, uncoated finish suited for use with cutting fluids

Compatibility

Designed for through-hole threading in steel at 10-32 UNF, 32 threads per inch, right-hand thread direction, using a standard tap holder sized for a 0.194-inch shank diameter.

Installation Notes

This tap is installed by a machinist or skilled tradesperson using a tap wrench, T-handle, or machine tapping head. Secure the workpiece fully before threading and use an appropriate cutting fluid for the material being tapped. Back the tap out periodically to break and clear chips even in through-hole applications. Do not apply side pressure to the tap shank, as spiral point taps are susceptible to breakage under lateral load.
