Eagle Cutting Tool SP-5625-18-P-I Hss Spiral Point Plug Tap

Product Description

The EAGLE CUTTING TOOL SP-5625-18-P-I is a 9/16-18 UNF high-speed steel (HSS) spiral point plug tap designed for threading operations in metal fabrication, mechanical maintenance, and industrial repair work. The spiral point geometry pushes chips forward ahead of the cutting flutes, keeping the flute area clear and allowing continuous feeding in through-hole applications. This tap is manufactured to plug chamfer specification, providing a standard 3-5 thread lead that balances starting ease with thread engagement depth. It is a useful tool for machinists, pipefitters, and maintenance technicians working with fine-thread fastener patterns.

This tap is suited for through-hole threading in a range of materials including mild steel, aluminum, brass, and similar machinable metals. The 9/16-18 UNF thread size is common in automotive, hydraulic, and general mechanical assemblies where fine-thread engagement and vibration resistance are priorities. The plug chamfer style makes it appropriate as a primary tapping tool for most standard through-hole jobs. Import-grade tooling at this specification is frequently used for production runs, secondary setups, and field service applications where high-volume tap replacement is expected.

Key Features

• 9/16-18 UNF thread form for fine-pitch through-hole tapping
• Spiral point design pushes chips ahead of the tap to reduce clogging
• Plug chamfer lead (approximately 3-5 threads) for general-purpose starting and full thread formation
• High-speed steel (HSS) construction provides adequate hardness and wear resistance for common shop metals
• Import-grade designation suitable for production and field service use

Compatibility

Designed as a general-purpose replacement or production tap for any application requiring a 9/16-18 UNF spiral point plug tap in standard tap wrench or machine holder chuck configurations.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench, tapping head, or CNC rigid tapping setup. Always apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Ensure the tap is started square to the drilled hole to prevent tap breakage. De-burr and clear the hole of chips before beginning the tapping operation.
