Eagle Cutting Tool SP-832-P-I 8-32 Hss Spiral Point Plug Tap

Product Description

The EAGLE CUTTING TOOL SP-832-P-I is an 8-32 high-speed steel (HSS) spiral point plug tap designed for cutting internal threads in through-hole applications. The spiral point geometry pushes chips ahead of the tap and out of the hole, reducing clogging and allowing faster, cleaner thread cutting compared to straight-flute designs. Built from HSS, this tap handles a wide range of ferrous and non-ferrous materials encountered in production machining, maintenance, and repair work. Machinists, millwrights, and maintenance technicians reach for spiral point plug taps when threading blind or through holes in steel, aluminum, and similar shop-floor materials.

This tap is suited for both hand tapping and machine tapping operations in light manufacturing, fabrication shops, and field maintenance environments. The 8-32 designation indicates a No. 8 major diameter thread with 32 threads per inch (UNC/UNF standard), a common fastener size found across electrical panels, enclosures, instrumentation hardware, and general mechanical assemblies. The plug chamfer style — typically 3 to 5 threads of lead — makes it the standard choice for starting threads in most through-hole applications without requiring a taper tap first.

Key Features

• Spiral point geometry pushes chips forward, reducing tap breakage and thread damage in through-hole work
• High-speed steel construction provides durability across ferrous and non-ferrous workpiece materials
• 8-32 thread form covers a widely used fastener size in electrical, mechanical, and instrumentation assemblies
• Plug chamfer lead suits the majority of standard through-hole tapping operations
• Compatible with both hand tapping and machine tapping setups

Compatibility

Designed as a standard replacement or stocking tap for any application requiring 8-32 internal threads in through-hole configurations, compatible with conventional tap handles, tapping heads, and CNC tap holders sized for the No. 8 shank diameter.

Installation Notes

Always secure the workpiece firmly before tapping. Use appropriate cutting fluid or tapping compound for the material being threaded to reduce heat and extend tool life. For machine tapping, verify spindle speed and feed rate are appropriate for the material and tap diameter before operation. Inspect the tap for wear or chipping before each use, as a damaged tap can seize in the hole or produce out-of-tolerance threads.
