Balax 54075-01T Straight Flute Tap 5/16-24 Unf Cobalt Tin

Product Description

The BALAX 54075-01T is a straight flute machine tap designed for cutting 5/16-24 UNF right-hand internal threads in a variety of workpiece materials. Built from M42 cobalt high-speed steel with a Titanium Nitride (TiN) coating, it delivers extended tool life in abrasive and demanding cutting conditions. The bottoming chamfer allows threading close to the bottom of blind holes. With 4 flutes and an H5 thread limit, this tap is suited for precision threading applications where dimensional consistency matters. It is installed by machinists and tool-and-die professionals using standard tapping equipment and hand-tapping tools.

This tap is appropriate for use in a wide range of production and maintenance machining environments. The BX600 series is rated for use in aluminum, cast iron, magnesium, and zinc workpieces, making it a versatile option for job shop and production floor applications. The bottoming chamfer design is particularly useful when threads must extend as deep as possible in a blind-hole application. The TiN finish reduces friction and improves wear resistance, supporting longer tool life between changes in high-cycle operations.

Key Features

• 5/16-24 UNF thread form with right-hand thread direction
• M42 cobalt steel construction for heat and wear resistance
• Titanium Nitride (TiN) coating reduces friction and extends tool life
• Bottoming chamfer for threading to near-bottom of blind holes
• H5 thread limit for close-tolerance threading applications
• 4-flute design compatible with standard tap wrenches and tapping heads
• Rated for aluminum, cast iron, magnesium, and zinc workpieces

Compatibility

Designed for use in aluminum, cast iron, magnesium, and zinc workpieces. Fits standard 5/16-inch tap holders and tapping heads accepting a 0.3180-inch shank diameter with a 0.2380-inch square drive. Part of the BALAX BX600 series.

Installation Notes

This tap is installed by machinists using a tap wrench, tapping head, or CNC tapping cycle. Always use the correct tap drill size - the specified 75% thread drill size for this tap is 0.2720 inches - and ensure the workpiece is securely fixtured before tapping. Apply appropriate cutting fluid for the workpiece material to reduce heat and improve thread quality. Never force a tap in a blind hole without confirming chip clearance, as straight flute taps do not eject chips forward.
