Kennametal 2623856 Indexable Square-shoulder End Mill

Product Description

The KENNAMETAL 2623856 is a 2-flute indexable square-shoulder end mill designed for precision milling operations in metal-cutting applications. Built on a 3/4-inch Weldon Flat shank, it accepts EC14.. and EP14.. series inserts secured by screw-clamp holding. The cutter runs a 0-degree lead angle, producing true 90-degree shoulder walls on the workpiece. Maximum depth of cut reaches 14.73mm (0.58 inches), and the tool supports a maximum spindle speed of 49,600 RPM. Through-coolant capability directs fluid directly to the cutting zone, improving chip evacuation and extending insert life in demanding cuts. The overall assembly weighs 1 pound and carries the ISO designation M1D075E1402W075L175.

This end mill is suited for square-shoulder roughing and semi-finishing passes on ferrous and non-ferrous materials in CNC machining centers. The Weldon Flat shank provides positive drive engagement, reducing slip under heavy radial loads. With a 1.75-inch head length and 96.01mm overall length, this toolholder fits standard machine spindles in both production shop and job-shop environments. Machinists and CNC operators running high-speed shoulder milling programs will find the 49,600 RPM rating appropriate for smaller-diameter, high-feed strategies.

Key Features

• 0-degree lead angle for true 90-degree square shoulders
• Through-coolant design improves chip evacuation and insert life
• Screw-clamp insert holding for repeatable indexing with EC14.. and EP14.. inserts
• Weldon Flat shank provides positive anti-rotation drive
• Maximum spindle speed of 49,600 RPM supports high-speed machining strategies
• 2-insert, 2-flute configuration balances material removal with chip clearance

Compatibility

Accepts EC14.. and EP14.. series indexable inserts. ISO number M1D075E1402W075L175 can be referenced for cross-compatibility verification with insert manufacturers.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the Weldon Flat shank firmly in the machine spindle using the appropriate set-screw torque per your machine tool manufacturer specifications before running. Verify insert seating and screw torque on all cutter inserts before spindle engagement. Connect through-coolant supply lines and confirm flow before initiating the cut cycle.
