Eagle Cutting Tool SP-3125-24-P-I Spiral Point Plug Tap

Product Description

The EAGLE CUTTING TOOL SP-3125-24-P-I is a 5/16-24 high-speed steel (HSS) spiral point plug tap designed for threading operations in metalworking and manufacturing applications. The spiral point geometry pushes chips forward ahead of the cutting action, reducing chip packing in through-hole threading. Made from HSS, this tap delivers reliable cutting performance across a range of ferrous and non-ferrous materials. It is used by machinists, maintenance technicians, and trade professionals who need a consistent, durable thread-cutting tool for production or repair work.

This tap is suited for through-hole tapping in materials such as mild steel, aluminum, brass, and similar machinable materials. The 5/16-24 thread specification indicates a 5/16-inch major diameter with a 24 threads-per-inch pitch, which falls in the UNF (Unified Fine) thread series. It is commonly used in precision assemblies, fastener repair, and component fabrication where fine thread engagement is required. The plug chamfer style makes it appropriate for both starting a thread in a hole and completing the cut in most standard through-hole applications.

Key Features

• 5/16-24 UNF thread form for fine-pitch through-hole tapping
• Spiral point geometry pushes chips forward, preventing packing in blind or through holes
• HSS construction provides durability and resistance to wear across common machinable materials
• Plug chamfer allows thread starting and full through-hole tapping in a single tool
• Minimum order quantity of 1, suitable for single-unit replacement or stock replenishment

Compatibility

Designed as a standard 5/16-24 UNF spiral point plug tap suitable for use with common tap handles, tapping attachments, and CNC tapping equipment that accept industry-standard shank dimensions for this tap size.

Installation Notes

This tap should be installed and operated by a qualified machinist or trained trade technician familiar with threading operations. Always use an appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Secure the workpiece properly before beginning the tapping operation, and ensure the tap is aligned perpendicular to the hole to avoid tap breakage. Follow applicable shop safety practices and machine operating procedures when using power tapping equipment.
