Sumitomo 1433932 Milling Insert Solid Carbide H1

Product Description

The SUMITOMO 1433932 is a solid carbide milling insert designed for precision metal removal in indexable milling operations. Manufactured to AECT insert style with a parallelogram shape and insert size code 1604, this insert carries Manufacturer Grade H1 and Material Grade C3, making it well suited for cutting non-ferrous metals. The bright, uncoated finish is intentional for these applications, reducing material adhesion on softer alloys. At 0.1968 inches thick with a 0.0310-inch corner radius, it delivers consistent chip formation and edge engagement across a range of milling passes. Licensed HVAC and machine trades technicians familiar with indexable tooling will recognize this as a direct-replacement insert for compatible milling heads.

This insert is intended for use in milling operations targeting non-ferrous workpiece materials, designated by primary workpiece material code N. It fits indexable milling cutters accepting the AECT insert style with size code 1604. Maximum depth of cut reaches 0.7080 inches, supporting both roughing and semi-finish passes on aluminum, copper, brass, and similar non-ferrous alloys. The 20-degree relief angle promotes clean cutting action and reduced cutting forces at the workpiece interface. Machining professionals in production, maintenance, and toolroom settings are the primary installers of this insert type.

Installation Notes

Insert replacement should be performed by qualified machinists or toolroom technicians with the machine powered down and spindle locked before any tooling change. Use a calibrated torque wrench and the cutter body manufacturer's recommended clamping screw to seat the insert correctly — do not overtighten by feel alone. Inspect the insert pocket for chips or debris before seating the new insert. Follow applicable shop safety and machine guarding procedures throughout the process.
