Balax 11967-010 Thread Forming Tap 10-24 Unc Bottoming Hss

Product Description

The BALAX 11967-010 is a thread forming tap designed for blind hole threading in the 10-24 UNC thread form with a 2B class of fit. Made from high-speed steel with a bright uncoated finish, this bottoming chamfer tap uses a cold-forming process to roll threads into the workpiece without cutting chips. The H7 thread limit ensures consistent tolerance control across production runs. With an overall length of 2.375 inches and a thread length of 0.600 inches, it fits standard tap handles and machine tool holders used by machinists and maintenance technicians in metalworking applications.

This tap is suited for light-duty ferrous and non-ferrous materials where chip-free thread forming is preferred over cutting. The bottoming chamfer with 2.5 chamfered threads allows threading close to the bottom of a blind hole. With a tapping depth of 0.875 inches and a single oil groove, it performs well in low-to-medium volume production and repair environments. It is commonly installed in manual tap handles or CNC tapping cycles where right-hand 10-24 UNC threads are required in blind holes.

Key Features

• Bottoming chamfer with 2.5 chamfered threads for threading near the bottom of blind holes
• High-speed steel construction for durability across ferrous and non-ferrous workpieces
• H7 thread limit for reliable tolerance control in 2B fit applications
• Thread forming design produces no chips, reducing chip-clearing downtime
• Single oil groove aids lubrication during the forming process
• Right-hand thread direction compatible with standard tooling and tap handles

Compatibility

Designed as an OEM-style replacement and production tap for applications requiring 10-24 UNC right-hand threads in blind holes with a 2B class of fit.

Installation Notes

Thread forming taps require a properly sized forming tap drill hole, which is typically larger than a standard cut tap drill - consult a thread forming tap drill chart before use. Apply a suitable tapping fluid or cutting oil to extend tap life and reduce galling, especially in aluminum or stainless. Power down or disengage the machine spindle before loading or removing the tap. Use a tap handle or machine holder rated for the shank diameter of 0.194 inches to avoid slippage.
