Ingersoll Cutting Tools 3012751 Indexable Chamfer End Mill

Product Description

The INGERSOLL CUTTING TOOLS 3012751 is a single-insert indexable chamfer end mill designed for milling operations requiring a 45-degree lead angle. It accepts one indexable insert secured by a screw-lock holding method and is built around a 0.75-inch Weldon Flat shank for positive rotational grip in the spindle. The cutting diameter ranges from 0.25 inches to 0.692 inches, with a maximum depth of cut of 0.22 inches. Overall length is 3.5 inches with a functional length of 1.5 inches. This tool is installed and operated by machinists and CNC tool-setters in metal-cutting production and job-shop environments.

The 3012751 is suited for chamfering, beveling, and edge-prep work on ferrous and non-ferrous workpieces in milling machine and CNC machining center applications. Its compact cutting head and single-insert configuration make it practical for light chamfer passes and countersink-style entry profiles in both roughing and finishing contexts. The Weldon Flat shank provides positive drive engagement and is compatible with standard Weldon-style end mill holders commonly found in vertical and horizontal machining centers.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing inserts or mounting the tool in the holder. Seat the Weldon Flat shank fully into the end mill holder before tightening the set screw to prevent axial pull-out during cutting. Follow the insert manufacturer guidelines for insert indexing and replacement intervals to maintain chamfer accuracy.
