Balax 17596-010 Extension Thread Forming Tap M3 X 0.5

Product Description

The BALAX 17596-010 is a metric extension thread forming tap designed for producing internal threads in ductile materials without cutting. Thread forming displaces material rather than removing it, resulting in stronger threads and no chips to clear. This tap is built from high-speed steel with a bright uncoated finish and carries a D6 thread limit with a 6H class of fit. The 3-inch overall length suits deep or hard-to-reach tapping applications where a standard-length tap cannot reach the work. Licensed machinists, toolroom technicians, and production floor operators typically use this tool on drill presses, CNC machining centers, or tapping machines.

This tap is suited for threading operations requiring an M3 x 0.5 metric coarse thread in blind or through holes where chip evacuation is a concern. The bottoming chamfer allows threading close to the bottom of a blind hole. The extended shank design is intended for setups with limited direct access to the workpiece, such as recessed bores or deep fixtures. The 5/8-inch thread length accommodates standard M3 engagement depths in typical production and repair scenarios.

Key Features

• Thread forming design produces chip-free internal threads in ductile materials
• Bottoming chamfer allows threading to the base of blind holes
• High-speed steel construction provides wear resistance across a range of workpiece materials
• Extended 3-inch overall length reaches deep or restricted workpiece locations
• D6 thread limit and 6H class of fit for consistent metric tolerance compliance
• Right-hand thread direction and right-hand flute direction for standard machine setups

Compatibility

Designed as an OEM-style replacement or direct-use thread forming tap for M3 x 0.5 metric coarse threading applications. Part of the BALAX BXEXT series.

Installation Notes

Thread forming taps require a properly sized forming tap drill rather than a standard tap drill diameter - consult the material and thread specification chart before drilling. Secure the workpiece and ensure the tap is properly aligned before engaging the spindle to prevent tap breakage. Apply appropriate tapping fluid for the workpiece material to reduce friction and extend tap life. Always follow shop safety practices and machine manufacturer guidelines when operating tapping equipment.
