Accupro 2500282 Square End Mill 5/8 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 2500282 is a single-end, square-profile carbide end mill designed for high-performance milling in ferrous and non-ferrous metals. Built from micrograin solid carbide and finished with a TiCN (Titanium Carbonitride) coating, it delivers strong wear resistance and edge retention at elevated cutting speeds. The 60-degree helix angle promotes aggressive chip evacuation and reduces cutting forces, making it well suited for demanding material removal. At 5/8 inch in diameter with a 1-5/8 inch length of cut, it handles slotting, profiling, and peripheral milling operations where rigidity and surface finish both matter. Machinist-grade tolerances on the mill diameter (+0.000/-0.002 inch) and shank diameter (+0.0001/-0.0004 inch) confirm OEM-level dimensional control.

This end mill is used in CNC machining centers and manual knee mills for job shop, production, and tool room applications. The 5/8 inch shank fits standard ER collet chucks, end mill holders, and shrink-fit tooling commonly found in production environments. With a 3-flute geometry and right-hand cut and flute direction, it balances chip room with feed rate capacity, making it practical for both slotting and finishing passes in steel, stainless, cast iron, and harder alloys. The regular-length body and 3-1/2 inch overall length keep deflection low in most standard-reach setups.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• TiCN coating improves wear resistance and reduces built-up edge in ferrous materials
• 60-degree high-helix angle promotes efficient chip evacuation and lower cutting forces
• 3-flute design balances flute volume with rigidity for slotting and profiling
• Center-cutting geometry allows plunge entry without a pre-drilled hole
• Tight shank and mill diameter tolerances support consistent tool runout in precision holders

Compatibility

Designed as a standard 5/8 inch shank end mill compatible with ER collet chucks, end mill holders, and shrink-fit tooling systems accepting 5/8 inch straight shanks. Suitable for CNC machining centers and manual milling machines configured for right-hand cutting tools.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked before loading or removing the tool from any holder. Seat the shank to the recommended insertion depth for the holder type in use and verify runout with a dial indicator before cutting. Follow machine tool manufacturer torque specifications for collet nuts and end mill holder set screws.
