Accupro 2500190 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The ACCUPRO 2500190 is a solid carbide square end mill designed for precision milling in metal, composites, and other hard materials. It features a 1/4 inch cutting diameter, a 3/4 inch length of cut, and a 60-degree helix angle that promotes aggressive chip evacuation and smooth surface finishes at high feed rates. The micrograin carbide substrate provides edge retention and resistance to chipping under demanding conditions. A TiCN coating reduces friction and extends tool life in ferrous and non-ferrous applications. This tool is used by machinists in job shops, aerospace, and general manufacturing environments.

This end mill is suited for slotting, profiling, and peripheral milling operations on CNC machining centers and manual mills. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. The 1/4 inch shank diameter fits common collets and tool holders in that size range. The regular length designation and 2.5 inch overall length keep it rigid for close-tolerance work where deflection must be minimized. It is a single-end, center-cutting tool capable of plunge entry as well as lateral passes.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• TiCN coating reduces friction and extends tool life in ferrous applications
• 60-degree helix angle promotes efficient chip evacuation at higher feed rates
• Center-cutting geometry allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand spiral for standard CNC and manual mill spindles
• Mill diameter tolerance of plus 0.000 / minus 0.002 inch for consistent part accuracy

Compatibility

Designed as a standard 1/4 inch shank square end mill compatible with collet chucks, end mill holders, and shrink-fit holders accepting 1/4 inch shanks on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and locked before loading or unloading the tool. Seat the shank to the full recommended insertion depth in the collet or holder before torquing the drawbar or nut. Inspect the cutting edges for chips or damage before each use and replace the tool if edge condition is compromised.
