Kennametal 2267548 Square-shoulder End Mill 1-1/2 in Cat 40

Product Description

The KENNAMETAL 2267548 is an indexable square-shoulder end mill engineered for precision milling operations in metalworking and machining environments. It accepts four EC18 or EP18 series indexable inserts secured by screw clamping, delivering reliable cutting performance at a 1.5-inch cutting diameter with a maximum depth of cut of 0.71 inches (18 mm). The through-coolant design channels fluid directly to the cutting zone via a 0.25-inch coolant hole, managing heat and chip evacuation during high-speed passes. With a maximum spindle speed of 29,020 RPM and a CAT 40 taper shank, this tool is built for rigid setups on machining centers used by experienced machinists and toolroom professionals.

This end mill is suited for square-shoulder milling, slotting, and contouring applications on steel, cast iron, and other ferrous materials in both production and job-shop settings. The CAT 40 taper shank makes it compatible with CAT 40 spindle toolholders common on vertical and horizontal machining centers in industrial and manufacturing facilities. It is a single-unit purchase appropriate for toolcrib restocking or direct machine assignment.

Installation Notes

Installation and tool changes should be performed by qualified machinists following the machine manufacturer's toolholding torque and retention procedures. Power down and lock out the spindle before changing inserts or mounting the tool. Ensure the CAT 40 taper and toolholder bore are clean and free of chips or burrs before seating. Verify coolant port alignment with the machine spindle coolant supply before initiating through-coolant operation.
