Kennametal 2624189 Indexable Square-shoulder End Mill

Product Description

The KENNAMETAL 2624189 is an indexable square-shoulder end mill designed for precision milling operations in metalworking and machining environments. With a 0.9701-inch cutting diameter and a maximum depth of cut of 0.58 inches (14.73 mm), this toolholder accommodates three EC14 or EP14 series inserts held in place by screws. The 1-inch Weldon flat shank provides secure, positive engagement in the spindle, and integrated through-coolant capability with a 0.25-inch coolant hole diameter supports chip evacuation and thermal management at the cutting zone. It carries a 0 degree lead angle for true square-shoulder profiling. Licensed machinists, CNC programmers, and tool-and-die professionals are the primary users.

This end mill is suited for square-shoulder milling, slotting, and side milling operations on steel, stainless steel, cast iron, and similar workpiece materials in production and job-shop environments. The Mill 1 cutter style is optimized for rigid setups where consistent shoulder squareness and controlled depths of cut are required. The through-coolant feature makes it particularly well-suited for deeper axial cuts where flood coolant cannot adequately reach the cutting zone. It is packaged and sold as a single toolholder unit without inserts.

Key Features

• 0.9701-inch cutting diameter with 0.58-inch maximum depth of cut for square-shoulder profiling
• 3-insert, 3-flute configuration using EC14 or EP14 insert styles, secured by screw clamping
• Weldon flat shank (1-inch diameter) provides positive drive and resists pull-out under heavy feed loads
• Through-coolant delivery via 0.25-inch coolant bore improves chip clearing and tool life in deep cuts
• 0 degree lead angle produces true 90-degree shoulder walls without angular compensation
• Maximum spindle speed of 40,100 RPM supports high-speed machining center applications

Compatibility

Designed for use with EC14 and EP14 series indexable inserts as specified by the manufacturer. ISO designation M1D097E1403W100L175 identifies the toolholder geometry for insert and application matching.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's spindle and toolholder guidelines. Ensure the machine spindle is fully powered down and locked out before mounting or removing the toolholder. Confirm Weldon set-screw engagement against the flat before tightening to the spindle manufacturer's specified torque. Verify coolant-through passages are clear and that the machine's through-spindle coolant pressure is compatible with the toolholder before operation.
