Accupro 12183225 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The ACCUPRO 12183225 is a solid carbide, square-profile end mill designed for precision milling in metalworking and machining applications. With a 0.250-inch cutting diameter, a 1.5-inch length of cut, and a 4.0-inch overall length, this tool falls into the extra-long category, giving machinists additional reach for deeper pockets and stepped features. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for demanding cuts in ferrous and non-ferrous materials. The uncoated finish makes it well suited for applications where a coating-specific coolant strategy is not required.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and pocket milling. The extra-long overall length makes it practical for deep-cavity work where standard-length tools cannot reach. The centercutting geometry allows plunge entry directly into the workpiece. Right-hand cut with right-hand spiral flutes is the standard configuration for conventional and climb milling on most setups. Machinists in production shops and toolrooms will find this tool appropriate for general-purpose milling where solid carbide performance is required.

Key Features

• Micrograin solid carbide construction for extended tool life and rigidity
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge entry without pre-drilling
• Extra-long 4.0-inch OAL provides reach for deep pockets and stepped features
• Right-hand cut and right-hand spiral flutes for standard CNC and manual mill setups
• Uncoated finish suitable for a wide range of general-purpose milling applications

Compatibility

Designed as a standard shank end mill compatible with 1/4-inch collets, ER collet chucks, and end mill holders used on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator after clamping before beginning a cut.
