Eagle Cutting Tool SP-540-P-I Hss Spiral Point Plug Tap 5-40

Product Description

The EAGLE CUTTING TOOL SP-540-P-I is a high-speed steel (HSS) spiral point plug tap designed to cut 5-40 unified fine (UNF) threads. The spiral point geometry pushes chips ahead of the cutting flutes, reducing clogging and allowing continuous feed through-hole threading operations. This tap is built for use in metal fabrication, mechanical assembly, and maintenance applications where accurate 5-40 thread production is required. At 0.1 pounds, it is a lightweight precision tool suited for manual or machine tapping setups.

The SP-540-P-I is used in through-hole threading applications across light manufacturing, HVAC equipment assembly, electrical enclosure fabrication, and general mechanical repair. The 5-40 thread size is common in small fastener applications found in instrument panels, electrical components, and light-duty mechanical assemblies. This import-grade tap provides a cost-effective option for shops and technicians needing reliable thread cutting performance in lower-volume or general-purpose work.

Key Features

• HSS construction provides hardness and wear resistance for threading steel, aluminum, and similar materials
• Spiral point design pushes chips forward, making it well suited for through-hole applications
• Plug chamfer style offers a balance between starting ease and full thread engagement
• 5-40 thread specification covers unified fine pitch threading requirements
• Lightweight at 0.1 pounds, easy to handle in manual or machine tap holders

Compatibility

Designed as an OEM-style replacement or direct-use tap for standard 5-40 thread applications in through-hole workpieces across general metalworking and mechanical assembly operations.

Installation Notes

Tap installation should be performed by a qualified machinist or tradesperson familiar with thread-cutting procedures. Always secure the workpiece firmly and use appropriate cutting fluid to reduce heat and extend tap life. Apply steady, even pressure and back off periodically to break chips during manual tapping. Never force a tap in a blind hole with a spiral point style, as this tool is optimized for through-hole use.
