Accupro 2500283 Square End Mill 7/16 in 5 Flute Carbide Ticn

Product Description

The ACCUPRO 2500283 is a solid carbide square end mill designed for precision metal removal in milling operations. It features a 7/16 inch (0.4375 inch) mill diameter, a 2 inch length of cut, and a 4 inch overall length, placing it in the long series category. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A titanium carbonitride (TiCN) coating improves surface hardness and wear resistance, extending tool life in ferrous and non-ferrous applications. Five flutes provide a balance of chip clearance and surface finish quality. Micrograin carbide substrate supports tighter tolerances and greater edge integrity compared to standard carbide grades. Licensed machinists and CNC tool-room technicians are the primary installers and operators.

This end mill suits general-purpose and finish milling work on steel, stainless, cast iron, and similar materials in job shop, tool-and-die, and production machining environments. The long series length of cut makes it well suited for slotting and profiling operations where extra reach into a workpiece or fixture clearance is needed. The single-end, right-hand cutting and right-hand flute configuration is the standard orientation for conventional CNC machining centers and manual vertical mills. The centercutting geometry allows plunge milling where the application calls for it.

Key Features

• 7/16 inch mill diameter with a tolerance of +0.000 / -0.002 inches for consistent dimensional accuracy
• 2 inch length of cut in the long series range, suited for deep slotting and profiling
• 5-flute spiral configuration balances chip evacuation with improved finish on ferrous materials
• 45-degree helix angle reduces axial cutting forces and promotes smooth chip flow
• TiCN coating provides enhanced hardness and wear resistance over uncoated or TiN-coated tools
• Micrograin solid carbide substrate delivers high rigidity and edge retention
• Centercutting design permits plunge entry cuts

Compatibility

Designed as an OEM-style replacement or direct procurement tool for standard 7/16 inch collet or end mill holder setups on CNC machining centers and manual vertical mills requiring a long series, 5-flute square end mill with a 7/16 inch shank diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and locked out before mounting or removing the tool from the holder. Use a properly sized collet or end mill holder that matches the 7/16 inch shank diameter and confirm shank runout is within acceptable limits before beginning a cut. Verify tool projection and stick-out length against the programmed depth of cut to avoid deflection or chatter.
