Sumitomo 1033W3Q Turning Insert DNGG431ESUJ H1 Carbide

Product Description

The SUMITOMO 1033W3Q is a solid carbide turning insert in the DN series, designed for precision metal cutting on CNC lathes and manual turning centers. This insert features an uncoated bright finish with a negative rake angle of 8 degrees, a 55-degree diamond shape, and a 1/64-inch corner radius. It measures 0.6102 inches in length with a 1/2-inch inscribed circle and a 3/16-inch thickness. Holding method is pin and screw, making it compatible with standard negative-style toolholders. Installation and operation are suited to licensed machinists and CNC operators working in production or job-shop environments.

This insert is optimized for turning non-ferrous metals, matching material grade N10 and primary workpiece material code N. The ESUJ chip breaker geometry is engineered for smooth, controlled chip formation in aluminum, brass, copper, and similar non-ferrous alloys. It performs well in both roughing and finishing passes where a tight corner radius is required. The neutral hand orientation allows use in a wide range of toolholder configurations, making it a practical choice for shops running varied part geometries on standard turning equipment.

Key Features

• Solid carbide construction with uncoated bright finish for non-ferrous metal applications
• 55-degree diamond insert shape with neutral hand for versatile toolholder compatibility
• ESUJ chip breaker geometry for controlled chip formation in aluminum and other non-ferrous alloys
• Negative rake at 8 degrees combined with N clearance code for stable cutting edge performance
• Pin and screw holding method for secure seating in standard DN-series toolholders
• Meets ANSI and ISO 13399 standards; ISO code DNGG 150404N-SUJ

Compatibility

Designed as an OEM-style replacement or direct-fit insert for DN-series negative toolholders accepting DNGG-style inserts with a 1/2-inch inscribed circle and pin-and-screw holding. Compatible with toolholder systems conforming to ANSI and ISO 13399 standards for DNGG 150404N-SUJ geometry.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to secure the pin-and-screw clamping mechanism without overtightening the clamp screw. Inspect the toolholder pocket for wear or debris before installing a new insert to ensure proper seating and edge repeatability.
