Kennametal 1023679 Indexable Chamfer End Mill

Product Description

The KENNAMETAL 1023679 is an indexable chamfer end mill designed for chamfering and edge-preparation operations on metalworking machines. It carries a 45-degree lead angle and accepts a cutting diameter range of 0.46 inches to 0.897 inches, giving the machinist flexibility across a range of workpiece sizes. The KIPR toolholder style and SDEB 26152 insert style are standard to this configuration. Overall length is 3 inches, with a head length of 1.22 inches and a maximum depth of cut of 0.195 inches. A single insert does the cutting work, secured by a screw-clamp holding method for rigid, repeatable positioning. The tool weighs 0.1801 pounds.

This chamfer end mill is suited for CNC machining centers and manual mills performing chamfer milling, countersinking, and edge-breaking on ferrous and non-ferrous materials. The Weldon Flat shank provides positive anti-rotation drive in compatible milling chucks and holders. With a shank diameter of 12.70 mm and a shank length of 45.21 mm, this tool is intended for use in standard toolholder setups found in production and job-shop environments. It is installed and operated by machinists and CNC programmers working with indexable milling tooling systems.
