Sandvik Coromant 6657475 Indexable Slotting Cutter 4in

Product Description

The SANDVIK COROMANT 6657475 is an indexable slotting cutter from the Corocut QD series, designed for precision slot milling in metalworking applications. It features a 4-inch cutter diameter, a 0.125-inch cutting width, and an arbor hole connection with a 1-inch bore. The cutter body holds 8 straight-tooth inserts secured by spring clamp, using QD-NG-0318-020E-PM inserts. Maximum depth of cut is 1.0158 inches (25.80 mm), and the tool is rated for a maximum of 5,400 RPM. This cutter is installed by machining professionals and toolroom technicians on horizontal or vertical milling machines and machining centers requiring repeatable, narrow-slot operations.

This slotting cutter is suited for production slot milling and grooving operations in ferrous and non-ferrous materials. The right-hand cutting direction and straight tooth geometry make it appropriate for consistent slotting passes in both job shop and production environments. The AQD.Y toolholder style integrates with compatible arbor setups used across a range of industrial milling machines. No Weldon flat is present on this cutter body.
