Sgs 30383 Square End Mill 1 in 4 Flute Solid Carbide Altin

Product Description

The SGS 30383 is a solid carbide square end mill designed for high-performance milling in demanding metal-cutting applications. It features a 1-inch cutting diameter, a 1.5-inch length of cut, and a 4-inch overall length, making it a regular-length tool suited for general profiling, slotting, and peripheral milling operations. The AlTiN coating provides heat resistance and extends tool life when cutting ferrous and high-temperature alloys. With four flutes and a micrograin carbide substrate, this end mill delivers fine surface finishes and consistent chip evacuation in production environments. It is installed and operated by machinists and CNC tooling professionals.

This end mill is built for use on CNC machining centers and manual mills where rigid setups and precise tolerances are required. The right-hand cut, right-hand spiral flute geometry with a 30-degree helix angle is well suited for a wide range of workpiece materials including steel, cast iron, stainless, non-ferrous alloys, and high-temperature alloys as indicated by material codes H, K, M, N, P, and S. The variable index design reduces chatter and improves surface finish quality during aggressive cuts. The Weldon flat shank provides a secure tool-holder interface that resists axial pullout under heavy milling loads.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for elevated heat resistance and extended tool life in ferrous and exotic alloy cutting
• 4-flute, right-hand cut and right-hand spiral configuration with 30-degree helix angle
• Variable index flute spacing reduces harmonic vibration and chatter
• Centercutting capable, allowing plunge entry into the workpiece
• Weldon flat shank for positive retention in set-screw style tool holders

Compatibility

Designed for use in standard 1-inch bore set-screw and Weldon-style tool holders on CNC machining centers and manual milling machines. Compatible with workpiece material types coded H, K, M, N, P, and S as specified by the manufacturer.

Installation Notes

This tool is installed by qualified machinists or CNC tooling personnel. Before tool changes, the machine spindle must be fully stopped and the control placed in a safe state per shop safety procedures. Torque the set screw against the Weldon flat using the tool holder manufacturer's specifications. Verify runout at the cutting edge with a dial indicator before beginning production cuts to avoid premature edge failure.
