Eagle Cutting Tool SP-6250-11-P-I Hss Spiral Point Plug Tap

Product Description

The EAGLE CUTTING TOOL SP-6250-11-P-I is a high-speed steel (HSS) spiral point plug tap designed for cutting 5/8-11 UNC threads in through-holes. The spiral point geometry pushes chips forward ahead of the cutting flutes, keeping the flute valleys clear and reducing the risk of chip packing during production runs. This tap is suited for use in ferrous and non-ferrous metals, plastics, and other machinable materials where a standard plug chamfer is appropriate. Machinists, toolroom technicians, and CNC operators install this tool in drill presses, CNC machining centers, and tapping machines.

This tap is intended for through-hole tapping applications where the 5/8-11 UNC thread form is required. The plug chamfer features 3-5 leading threads of taper, making it the standard choice for general-purpose tapping where the tool can pass through the workpiece. It is well suited for production threading in shops handling structural components, flanges, brackets, and similar workpieces requiring a 5/8-11 fastener engagement.

Key Features

• 5/8-11 UNC thread size for common structural and mechanical fastener applications
• High-speed steel (HSS) construction provides hardness and wear resistance across a broad range of machinable materials
• Spiral point geometry drives chips forward to prevent packing in through-hole applications
• Plug chamfer (3-5 thread lead) provides a balance of cutting ease and thread engagement for general-purpose use
• Minimum order quantity of 1 allows single-unit procurement

Compatibility

Designed as a general-purpose replacement or stock tap for through-hole 5/8-11 UNC tapping operations in standard tapping machines, drill presses, and CNC machining centers accepting the corresponding shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following established safe machining practices. Secure the workpiece firmly before beginning the tapping operation and ensure the spindle and tap are properly aligned to avoid tap breakage or thread distortion. Use an appropriate cutting fluid or tapping compound recommended for the workpiece material to extend tool life and improve thread quality. Never attempt to reverse a broken tap with power feed; consult safe tap-extraction procedures for removal.
