Eagle Cutting Tool SP-7500-16-P-I Hss Spiral Point Plug Tap

Product Description

The EAGLE CUTTING TOOL SP-7500-16-P-I is a 3/4-16 high-speed steel (HSS) spiral point plug tap designed for threading operations in ferrous and non-ferrous materials. The spiral point geometry pushes chips forward ahead of the cutting zone, keeping the flutes clear during through-hole tapping. This tap is ground to plug chamfer style, which means it enters the work with a gradual lead, making it suitable for general-purpose machine and hand tapping in production and maintenance environments. Machinists, tool and die makers, and maintenance technicians are the primary users of this tool.

This tap is suited for through-hole threading applications requiring a 3/4 inch nominal diameter with 16 threads per inch (UNF fine thread pitch). It performs in materials including mild steel, aluminum, brass, and similar machinable alloys. Typical applications include machine shops, manufacturing facilities, and field maintenance settings where accurate threaded holes are required in moderate to hard materials.

Key Features

• HSS construction provides hardness and wear resistance for extended tap life in common metals
• Spiral point design pushes chips forward, reducing chip packing in through-hole tapping
• Plug chamfer lead allows progressive thread engagement for controlled cutting action
• 3/4-16 UNF thread form suits fine-pitch applications requiring high thread engagement strength
• Compatible with standard tapping machines, CNC machining centers, and hand tap wrenches

Compatibility

Designed as a general-purpose replacement or production tap for through-hole tapping operations requiring a 3/4-16 UNF thread form in standard machinable materials.

Installation Notes

This tap is installed by a machinist or qualified technician using a tap wrench, tapping head, or CNC rigid tapping cycle. Always use appropriate cutting fluid matched to the workpiece material to extend tap life and improve thread finish. Secure the workpiece firmly before tapping to prevent movement. Inspect the tap for chipping or wear before each use and replace if cutting edges are damaged.
