Eagle Cutting Tool SP-1228-P-I Hss Spiral Point Plug Tap 12-28

Product Description

The EAGLE CUTTING TOOL SP-1228-P-I is a 12-28 high-speed steel (HSS) spiral point plug tap designed for cutting internal threads in through-hole applications. The spiral point geometry pushes chips forward ahead of the cutting flutes, reducing chip clogging and allowing cleaner thread formation at higher feed rates. Built from HSS, the tap delivers consistent cutting performance across a range of ferrous and non-ferrous materials. This is an import-grade tap suited for production environments, maintenance shops, and general metalworking operations where cost-effective tooling is required.

This tap is used in machine tapping and hand tapping of through holes requiring a 12-28 unified fine (UNF) thread profile. It is appropriate for use in drill presses, CNC machining centers, tapping machines, and manual tap handles. Machinists, maintenance technicians, and toolroom professionals use this tap for threading steel, aluminum, brass, and similar workpiece materials in both light manufacturing and repair applications.

Key Features

• Spiral point design pushes chips forward, ideal for through-hole tapping
• High-speed steel (HSS) construction for durability across common metals
• 12-28 thread specification for unified fine thread applications
• Plug chamfer style for starting ease in through-hole work
• Import-grade construction offers cost-effective performance for general use

Compatibility

Designed as an OEM-style replacement and standard-fit tool for applications requiring a 12-28 UNF spiral point plug tap in HSS construction.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with tapping operations. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for a 12-28 thread before tapping begins. Apply appropriate cutting fluid to extend tool life and improve thread finish. Never force a tap against resistance, as this may result in tap breakage.
