Balax 11525-000 Thread Forming Tap 6-40 Unf Plug Hss

Product Description

The BALAX 11525-000 is a thread forming tap designed for through-hole threading applications in metalworking and precision machining environments. It cuts a 6-40 UNF right-hand thread using a plug chamfer with 4 chamfered threads for controlled entry. Built from high-speed steel with a bright uncoated finish, this tap delivers consistent thread geometry in production and repair work. The BXP series design includes a single oil groove to aid lubrication during the forming process. At 2 inches overall length and a thread limit of H5, it suits tight-tolerance applications requiring a 2B class of fit. Machinists and tool-and-die professionals reach for this tap when thread quality and dimensional consistency are the priority.

This tap is suited for through-hole threading in ferrous and non-ferrous materials where a plug chamfer provides the right balance between starting ease and thread engagement depth. The 6-40 UNF thread specification makes it a common choice for small fastener applications in electronics, instrumentation, and precision mechanical assemblies. It is compatible with standard tapping chucks and CNC rigid tapping setups where right-hand threading is required.

Key Features

• 6-40 UNF right-hand thread specification for small fastener applications
• Plug chamfer with 4 chamfered threads for controlled thread engagement entry
• High-speed steel construction for durability across ferrous and non-ferrous materials
• H5 thread limit with 2B class of fit for tight-tolerance threading work
• Single oil groove aids lubrication and chip clearance during the forming cycle
• BXP series, bright uncoated finish, no coolant-through requirement

Compatibility

Designed as an OEM-style replacement or direct-use thread forming tap for through-hole 6-40 UNF applications in standard tapping chucks, tap holders, and CNC rigid tapping setups.

Installation Notes

Thread forming taps are installed and operated by machinists or tool-and-die technicians familiar with tapping speeds, feed rates, and workpiece fixturing. Ensure the workpiece is properly clamped and the pilot hole diameter is correctly sized for a thread forming operation before starting. Apply appropriate tapping fluid or cutting oil to the tap and workpiece to protect the tap and maintain thread quality. Follow shop safety practices and machine manufacturer guidelines when setting up tapping operations.
