Accupro 2500305 Square End Mill 1 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 2500305 is a single-end square end mill engineered for precision milling in demanding shop environments. Built from micrograin solid carbide and coated with titanium carbonitride (TiCN), it delivers hardness and wear resistance suited to ferrous and non-ferrous materials. The mill measures 1 inch in diameter with a 1-1/4 inch length of cut and a 3 inch overall length, with a matching 1 inch shank diameter. Five right-hand spiral flutes at a 45-degree helix angle promote aggressive chip evacuation and a smooth surface finish. Centercutting capability allows plunge entry. This stub-length geometry provides rigidity in high-load face milling, slotting, and profiling operations.

The 2500305 is suited for CNC machining centers and manual mills in production and toolroom settings. Its stub-length profile keeps deflection low during full-width slotting or deep side-milling passes. The TiCN coating extends tool life in alloy steels, stainless steel, cast iron, and hardened materials where uncoated carbide would wear prematurely. Machinists and toolroom operators running finishing or semi-finishing passes will find the five-flute count effective at higher feed rates compared to standard four-flute designs.

Key Features

• Micrograin solid carbide substrate for rigidity and edge retention
• TiCN coating provides enhanced hardness and wear resistance
• 5 right-hand flutes at 45-degree helix for efficient chip evacuation
• Centercutting design allows direct plunge milling
• Stub-length geometry minimizes deflection in heavy-load passes
• Mill diameter tolerance of +0.000 / -0.002 inches for close-tolerance work

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1 inch straight shank end mill with right-hand cutting direction.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout. Power down and lock out the spindle before seating or removing the end mill from the holder. Use a proper end mill holder or collet sized to the 1 inch shank; verify shank diameter tolerance against holder specs before clamping. Inspect the cutting edges and coating for chips or wear before each use.
