Balax 30095-000 Spiral Point Tap 1/4-28 Unf 3 Flute

Product Description

The BALAX 30095-000 is a spiral point tap designed for threading 1/4-28 UNF right-hand threads in through-hole applications. Built from M42 Powdered Metal High-Speed Steel (PM-HSS) with a bright uncoated finish, this plug-chamfer tap is suited for production and maintenance threading work. The spiral point geometry pushes chips forward ahead of the tap, keeping the flutes clear during blind or through-hole operations. With an H5 thread limit and 3 flutes, it delivers consistent thread form across a wide range of workpiece materials. Licensed machinists, tool-and-die technicians, and maintenance mechanics rely on this tap for accurate 28 TPI thread cutting.

The 30095-000 is rated for use in aluminum, brass, bronze, carbon steel, copper, magnesium, stainless steel, wrought aluminum alloy, and zinc. The plug chamfer makes it a standard choice for through-hole threading where the tap can run fully through the material. The BX100 series designation identifies it as part of a production-grade tap line. It is a practical fit for job-shop work, CNC tapping centers, and manual drill press setups where a reliable 1/4-28 UNF thread is required.

Key Features

• Spiral point geometry pushes chips forward, reducing clogging in through-hole tapping
• M42 Powdered Metal HSS construction for improved wear resistance and edge retention
• H5 thread limit for consistent oversize tolerance control
• Plug chamfer for standard through-hole thread starting
• Right-hand thread direction, 28 threads per inch, UNF standard
• Bright uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed for cutting 1/4-28 UNF right-hand threads in aluminum, brass, bronze, carbon steel, copper, magnesium, stainless steel, wrought aluminum alloy, and zinc workpieces. Compatible with standard 1/4-28 UNF tap holders and tapping chucks sized for a 0.255 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician following standard tapping procedures. Always ensure the workpiece is securely fixtured and the correct tap drill size for 1/4-28 UNF is used before tapping. Apply an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Inspect the tap for wear or chipping before each use and replace if edge condition is degraded.
