Kennametal 2267534 Square-shoulder End Mill 1 in 2 Flute

Product Description

The KENNAMETAL 2267534 is an indexable square-shoulder end mill designed for precision milling operations in metal-cutting applications. It carries ISO designation M1D100E1802C100L800 and accepts two EC18 or EP18 series inserts secured by screw clamp. The tool features a 1-inch cutting diameter, a maximum depth of cut of 18 mm (0.71 inches), and a 0-degree lead angle that produces true 90-degree shoulder walls. Through-coolant delivery via a 0.25-inch coolant hole keeps the cutting zone clear and extends insert life during extended cuts. The cylindrical shank measures 1 inch in diameter and is suitable for standard milling chucks and toolholders used on CNC machining centers.

This end mill is suited for square-shoulder milling, face milling, and side milling in ferrous and non-ferrous materials on vertical and horizontal CNC machining centers. The 2-flute, 2-insert configuration supports aggressive material removal while maintaining surface finish quality. At 8 inches overall length with a 4.25-inch shank length, the tool provides adequate reach for most production milling setups. It is typically installed and set up by machinists or CNC operators working in job shop, production, or tool-and-die environments where repeatable, tight-tolerance shoulder milling is required.

Key Features

• 1-inch cutting diameter with 0-degree lead angle for true 90-degree square shoulders
• Accepts EC18 and EP18 series indexable inserts, secured by screw clamp
• Through-coolant design with 0.25-inch coolant hole diameter for chip evacuation and tool life
• Maximum spindle speed rated to 37,000 RPM
• Cylindrical shank compatible with standard milling chucks and shrink-fit holders
• 2-flute, 2-insert configuration balances material removal rate and wall finish

Compatibility

Designed for use with EC18 and EP18 series indexable milling inserts. Verify insert grade and geometry selection against the workpiece material and cutting parameters before use.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in an E-stop or locked-out state before mounting or removing the tool. Confirm the toolholder bore and retention system match the 1-inch cylindrical shank diameter before clamping. Verify coolant-through passages in the toolholder are aligned and unobstructed before initiating a cut.
