Sumitomo 19T5336 Carbide Turning Insert 80 Deg Diamond

Product Description

The SUMITOMO 19T5336 is a CNMG-style carbide turning insert designed for precision metal removal in demanding machining environments. Coated with TiAlSiN via a PVD process under the Absotech Bronze designation, this insert delivers high wear resistance with moderate toughness. It features an 80-degree diamond (rhombic) insert shape, a 0.5-inch inscribed circle, a corner radius of 0.0469 inches, and a thickness of 0.1875 inches. The neutral hand orientation and negative rake geometry suit it to rigid setups on CNC turning centers. It is indexed using a screw-holding method and belongs to the AC5000S series, grade AC5015S.

This insert is engineered for light to medium machining of non-ferrous metals and superalloys, aligning with primary workpiece material code S. Typical applications include turning of nickel-based alloys, titanium, and other high-temperature alloys where tool life and edge stability are critical. The EGU chip breaker geometry supports controlled chip evacuation across a range of feed rates and depths of cut suited to finish and semi-finish passes. It conforms to ANSI insert code CNMG433 and ISO insert code CNMG120412, making it a direct fit in standard CNMG toolholders.

Key Features

• 80-degree diamond insert shape (CNMG) with negative rake and neutral hand
• EGU chip breaker optimized for light and medium machining operations
• 0.5-inch inscribed circle, 0.0469-inch corner radius, 0.1875-inch thickness
• Screw-holding method with 0.2031-inch hole diameter for secure clamping
• Conforms to ANSI and ISO 13399 standards; ISO code CNMG120412N-GU

Compatibility

Fits standard CNMG toolholders accepting a 0.5-inch inscribed circle insert with screw clamping. Compatible with ANSI insert code CNMG433 and ISO insert code CNMG120412 tooling systems. Intended for machining non-ferrous metals and superalloys per primary workpiece material code S.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the turret or toolholder is indexed and the machine is in a safe, powered-down state before seating or replacing inserts. Use the correct torque driver for the clamping screw to avoid insert movement or seat damage. Verify insert orientation and chip breaker direction against the toolholder specification before resuming cuts.
