Balax 12263-010 Extension Thread Forming Tap 10-32 Unf

Product Description

The BALAX 12263-010 is a thread forming extension tap designed for creating internal threads in ductile materials without cutting or removing chips. Built from high-speed steel with a bright uncoated finish, this tap uses a bottoming chamfer for threading close to the bottom of blind holes. The 10-32 UNF thread size, H3 thread limit, and 3B class of fit make it a precise tool for controlled tolerance applications in manufacturing and assembly work. With a 6-inch overall length, it reaches into deep recesses and extended cavities where standard-length taps cannot access.

This extension tap is suited for production environments and maintenance applications requiring 10-32 UNF internal threads in aluminum, mild steel, and other formable metals. The bottoming chamfer allows threading to within a few threads of the bottom of a blind hole. Its reduced-diameter shank profile clears surrounding fixtures, and the right-hand flute direction is compatible with standard tapping equipment. Machinists and maintenance technicians working on assemblies with deep bosses or recessed threaded holes will find the extended reach essential.

Key Features

• Thread forming design displaces material rather than cutting, producing stronger threads in ductile metals
• 6-inch overall length provides extended reach into deep holes and recessed cavities
• Bottoming chamfer allows threading close to the bottom of blind holes
• High-speed steel construction offers durability across a range of formable workpiece materials
• H3 thread limit and 3B class of fit ensure controlled thread tolerance
• Right-hand flute direction compatible with standard tapping machines and tap handles

Compatibility

Designed for use in 10-32 UNF tapping applications requiring a bottoming chamfer and extended reach. Part of the BALAX BXEXT series of extension taps.

Installation Notes

Thread forming taps require a properly sized forming hole, which is typically larger than a standard cut tap drill size - consult a thread forming drill chart for the correct hole diameter before tapping. Power down or de-energize any machine before installing or removing the tap from a holder. Use tapping fluid appropriate for the workpiece material to extend tool life and maintain thread quality. Ensure the tap is driven straight and aligned with the hole axis to prevent tap breakage.
