Kennametal 1023581 Indexable Square-shoulder End Mill 1/2 in

Product Description

The KENNAMETAL 1023581 is an indexable square-shoulder end mill designed for precision milling operations in metalworking and machining environments. Built around the KICR050SD260 cutter style, it accepts a single SDEB 2615 insert secured by a screw-lock holding method, delivering a 90-degree lead angle suitable for true square-shoulder profiling and step milling. The tool features a 1/2 inch cutting diameter with a maximum depth of cut of 7.11 mm (0.28 inches) and runs up to 11,000 RPM. Overall length is 3 inches, keeping the setup compact and rigid. Licensed machinists and CNC operators working on mill machines install this tool in standard toolholding setups.

This end mill is suited for single-flute, one-insert square-shoulder milling on CNC machining centers and manual knee mills handling ferrous and non-ferrous materials. The 1/2 inch cylindrical shank with a 12.70 mm diameter and a shank length of approximately 1.78 inches fits standard collet chucks and side-lock holders commonly found in production and job-shop environments. It is a practical choice when insert changeability and consistent shoulder geometry are priorities over solid-carbide tooling.

Key Features

• KICR cutter style with 0-degree lead angle for true 90-degree square-shoulder milling
• Single SDEB 2615 insert, screw-held for repeatable positioning and fast changeover
• 1/2 inch cutting diameter with a maximum depth of cut of 7.11 mm (0.28 inches)
• Maximum spindle speed of 11,000 RPM
• Cylindrical shank at 1/2 inch (12.70 mm) diameter, 1.78 inch shank length
• No coolant-through design - external coolant or dry cutting applies

Compatibility

Designed for use with the SDEB 2615 insert. ISO designation KICR050SD260 confirms the cutter geometry and insert pocket specification. Fits standard 1/2 inch collet or side-lock toolholding systems on CNC and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and locked out before mounting or changing inserts. Torque the insert-retention screw to the tool manufacturer recommendation found in the tooling documentation supplied with the insert. Confirm runout at the cutting edge after installation before engaging the workpiece.
