Balax 54015-01T Straight Flute Tap 8-32 Unc Bottoming Cobalt

Product Description

The BALAX 54015-01T is a straight flute machine tap designed for cutting 8-32 UNC internal threads in a range of common metals. Built from M42 cobalt high-speed steel and finished with a Titanium Nitride (TiN) coating, it delivers extended tool life in abrasive and harder workpiece materials. The bottoming chamfer allows threading close to the bottom of a blind hole. With 3 flutes, an overall length of 2.125 inches, and a thread length of 0.5 inches, this tap suits production and maintenance machining applications where precision thread form and consistent tool life matter.

This tap is suited for threading operations in aluminum, cast iron, magnesium, and zinc. The bottoming chamfer style makes it the right choice when a through-tap or plug tap cannot reach the required thread depth in a blind hole. It is used in machine tapping setups on drill presses, CNC machining centers, and manual tapping arms. The BX600 series designation identifies it within the BALAX oversize tap line, where the H5 thread limit and oversize specification are used to compensate for specific material springback conditions.

Key Features

• M42 cobalt high-speed steel construction for improved heat and wear resistance
• Titanium Nitride (TiN) coating reduces friction and extends tool life in production use
• Bottoming chamfer allows threading to within 1-2 threads of blind hole bottom
• H5 oversize thread limit compensates for material springback in applicable workpieces
• Right-hand thread direction, no coolant-through requirement
• Rated for aluminum, cast iron, magnesium, and zinc material applications

Compatibility

Designed for machine tapping of 8-32 UNC threads in aluminum, cast iron, magnesium, and zinc. The 75 percent thread drill size for this tap is 0.1340 inches. Part of the BALAX BX600 series oversize tap line.

Installation Notes

This tap is installed and used by machinists and maintenance technicians operating drill presses, CNC machining centers, or manual tapping equipment. Always secure the workpiece and ensure the correct 0.1340-inch drill size has been used before tapping. Apply appropriate cutting fluid for the workpiece material to reduce heat buildup and extend tool life. Inspect the tap for wear or chipping before each use, as a damaged tap can destroy thread quality and jam in blind holes.
