Sumitomo 1033357 Carbide Turning Insert 80 Diamond

Product Description

The SUMITOMO 1033357 is an uncoated solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to ANSI and ISO 13399 standards, this insert carries the ANSI code CCGT32.50.5NAG and ISO code CCGT 09T302N-AG. It features an 80-degree diamond shape with a positive rake angle of 20 degrees and a relief angle of 7 degrees, making it well suited for light, finishing cuts in non-ferrous materials. The manufacturer grade designation is H1, and the chip breaker style is NAG. The insert is held in place using a pin and screw holding method and is compatible with standard C-style toolholders with G tolerance and C clearance.

This insert is intended for turning applications involving non-ferrous metals such as aluminum, copper, and brass alloys. The uncoated solid carbide construction and positive rake geometry minimize cutting forces and reduce built-up edge when machining these materials. It is typically used in residential and industrial machine shops, toolrooms, and production environments where fine surface finish and tight dimensional tolerances are required. The NAG chip breaker geometry is optimized for light finishing passes at higher spindle speeds. This insert ships individually and carries a minimum order quantity of 10 units.

Key Features

• 80-degree diamond insert shape with positive 20-degree rake angle for low cutting forces
• Uncoated solid carbide construction optimized for non-ferrous metal machining
• H1 manufacturer grade with NAG chip breaker for fine finishing cuts
• 3/8 inch inscribed circle with 0.0078 inch corner radius for tight-radius finishing
• Conforms to ANSI and ISO 13399 standards for broad toolholder compatibility
• Neutral cutting direction - suitable for both left- and right-hand approaches

Compatibility

Designed as a direct-fit replacement or standard insert for C-style toolholders accepting CCGT geometry inserts with G tolerance and C clearance, per ANSI and ISO 13399 specifications. Primary workpiece material code is N, covering non-ferrous metals.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. 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 system to the toolholder manufacturer torque specification. Inspect the insert pocket and clamping components for wear or damage before seating a new insert.
