Sandvik Coromant 5723084 Turning Insert CCET21.503-UM 1105

Product Description

The SANDVIK COROMANT 5723084 is a solid carbide turning insert carrying ANSI code CCET21.503-UM 1105 and ISO code CCET 06 02 01-UM 1105. It features an 80-degree diamond (rhombic) shape with a positive side clearance and a TiAlN coating engineered for high wear resistance in super alloy and special-material applications. The insert measures 0.25 inches on the inscribed circle, 0.25 inches in length, and 0.094 inches thick, with a 0.10 mm corner radius. It is designed for roughing and medium machining operations where consistent tool life and edge integrity are critical. CNC machinists and tool-room technicians working in aerospace, medical, and energy sectors are the primary installers of this insert.

This insert is suited for turning operations on difficult-to-machine materials classified under ISO material group S, including nickel-based superalloys, titanium alloys, and cobalt-based alloys. The UM chip breaker geometry supports both roughing and medium machining passes, making the insert adaptable across finishing and semi-finishing stages when stock removal rates and surface consistency matter. It is held in place by a screw-clamp method and fits toolholders designed for CCET-style inserts with the corresponding pocket geometry.

Key Features

• TiAlN coating delivers high wear resistance for super alloy and special-material turning
• 80-degree diamond (rhombic) insert shape with 7-degree relief angle and positive clearance
• UM chip breaker geometry supports roughing and medium machining operations
• 0.10 mm corner radius suits general turning with controlled edge engagement
• Screw-held mounting method for secure, repeatable insert indexing
• Solid carbide substrate with grade 1105 for thermal and mechanical stability

Compatibility

Designed for screw-clamp toolholders accepting CCET-style inserts with an ANSI size code of 21.503 and ISO size code 060201. Verify toolholder pocket geometry and clearance angle before installation. No specific compatible toolholder model numbers were provided in the product data.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine in a full stop and all motion axes locked or in a safe state per shop safety procedures. Use the correct torx or hex key to torque the clamping screw according to the toolholder manufacturer specification. Inspect the insert pocket for chips or debris before seating the new insert. Never force the insert into the pocket, as this can damage the seating surface or fracture the carbide.
