Kennametal 2624246 Indexable Square-shoulder End Mill

Product Description

The KENNAMETAL 2624246 is an indexable square-shoulder end mill designed for precision milling operations in metalworking and machining environments. Built on a CAT 40 taper shank, this toolholder accepts EC14.. and EP14.. insert styles and is engineered for square-shoulder milling with a 0-degree lead angle. The 1-inch cutting diameter and 3-flute configuration support efficient material removal in ferrous and non-ferrous applications. Through-coolant delivery via a 0.25-inch coolant hole keeps cutting temperatures under control and extends insert life during demanding cuts. Installation and use require a compatible CAT 40 spindle and appropriate inserts purchased separately.

This end mill is suited for CNC machining centers running CAT 40 tooling. The Mill 1-14 cutter style makes it applicable to square-shoulder profiling, slotting, and face milling operations in production and job-shop environments. With a maximum RPM rating of 39,200, it supports high-speed machining strategies on modern CNC platforms. The overall length of 144.45 millimeters and a shank length of 71.44 millimeters provide adequate reach for typical milling setups without sacrificing rigidity. Machining technicians and CNC programmers working in aerospace, die-mold, and general manufacturing will find this toolholder a direct fit for demanding square-shoulder applications.

• Maximum spindle speed of 39,200 RPM supports high-speed machining strategies

Compatibility

Accepts EC14.. and EP14.. insert styles. Requires a CAT 40 taper spindle interface. Designed as an OEM-style indexable toolholder for CNC machining centers equipped with CAT 40 tooling systems.

Installation Notes

Installation should be performed by a qualified machining technician familiar with CAT 40 toolholder assembly and CNC setup procedures. Power down and lock out the machine spindle before mounting or removing the toolholder. Inserts must be seated and secured with the appropriate screw-clamp torque per the insert manufacturer's specifications before running. Verify coolant line connection and through-spindle coolant pressure compatibility with your machine tool before operation.
