Sumitomo 1433728 Milling Insert Square H1 Solid Carbide

Product Description

The SUMITOMO 1433728 is a solid carbide milling insert in a square SEET style, manufactured to grade H1 with a bright uncoated finish. It measures 0.1563 inches thick and 0.5276 inches in inscribed circle diameter, placing it in the 13T3 insert size classification. This single-sided insert carries a 20-degree relief angle, making it well-suited for positive-rake milling applications. Licensed machinists and tooling technicians install this insert into compatible milling cutter bodies for cutting non-ferrous materials. The uncoated solid carbide construction provides sharp edge retention on softer, abrasive workpieces where coated grades can cause built-up edge.

This insert is designed for milling operations on non-ferrous metals, including aluminum alloys, copper alloys, and similar K and N workpiece material groups. It is used in CNC machining centers and manual milling setups where a square insert geometry with a positive relief angle is specified. The 13T3 size code helps machinists cross-reference toolholder pocket compatibility when selecting inserts for a given cutter body. This insert ships individually but is subject to a minimum order quantity of 10 units.

Compatibility

Designed for use in milling cutter bodies that accept SEET-style square inserts with a 13T3 size pocket. Verify toolholder pocket dimensions against the inscribed circle range of 0.5100 to 0.6000 inches and thickness range of 0.1500 to 0.1750 inches before ordering.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before removing or seating any insert. Use the correct torque wrench and manufacturer-specified clamping hardware for the cutter body to avoid fracturing the carbide substrate. Inspect the insert pocket for chips or debris before seating a new insert.
