Sandvik Coromant 5743943 Milling Insert CD10 Diamond Tipped

Product Description

The SANDVIK COROMANT 5743943 is a single-sided, square milling insert in the R245 series, tipped with polycrystalline diamond (CD10 grade) and left uncoated for a bright finish. Designed for high-performance milling of non-ferrous metals, it features a positive rake angle of 0 degrees and a corner radius of 0.0591 inches (1.50 mm). The insert measures 0.1563 inches (3.97 mm) thick with an inscribed circle of 0.5276 inches (13.40 mm). Secured by a screw-holding method, it is intended for installation by machinists and CNC tooling technicians working with aluminum, copper, and other non-ferrous workpiece materials.

This insert fits the R245 cutter series and is suited for face milling and shoulder milling operations on non-ferrous metals in both production shop and job-shop environments. The CD10 diamond-tipped grade provides consistent edge integrity on abrasive non-ferrous materials where carbide inserts wear prematurely. The flat-top chip breaker geometry and corner-rounded cutting edge support smooth chip evacuation. With a maximum depth of cut of 0.0984 inches (2.50 mm), this insert is well matched to finish and semi-finish milling passes requiring tight tolerances.

Key Features

• Flat-top chip breaker geometry — promotes clean chip evacuation in non-ferrous applications
• Right-hand cut, single-sided insert with one cutting edge per insert
• Screw-holding method — secure clamping in compatible R245 toolholders

Compatibility

Designed for use in R245 series milling cutters. ANSI and ISO designation: R245-12 T3 E CD10. Insert size code 12T3. Compatible with R245 cutter bodies accepting a square insert with a 0.1614-inch hole diameter and 0.5276-inch inscribed circle.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the spindle before removing or seating inserts. Use the appropriate Torx or hex key for the clamping screw and ensure the insert seats fully against the pocket walls before torquing. Inspect the insert pocket for chips or wear before fitting a new insert to maintain proper seating and runout.
