Sgs 30181 Square End Mill 5/8 in 4 Flute Solid Carbide

Product Description

The SGS 30181 is a solid carbide square end mill designed for high-precision milling operations across a broad range of workpiece materials. With a 0.625-inch mill diameter, 4 flutes, and a 30-degree helix angle, it delivers clean, efficient chip evacuation and stable cutting performance. The variable index flute geometry reduces chatter and improves surface finish compared to standard equally-spaced designs. Manufactured from micrograin carbide in a bright, uncoated finish, it is suited for applications where coating compatibility or post-machining inspection is a priority. This tool is single-end, right-hand cut with a right-hand spiral flute configuration.

This end mill is appropriate for machining a wide range of materials including cast iron, non-ferrous metals, steel, stainless steel, high-temperature alloys, and non-metallic materials, corresponding to material codes H, K, M, N, P, and S. The 1.25-inch length of cut and 3.5-inch overall length make it well suited for standard-depth peripheral and slot milling in vertical machining centers and CNC mills. The Weldon flat shank provides positive drive retention in standard end mill holders and set-screw style toolholders.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• Variable index flute spacing reduces harmonic chatter during cutting
• 30-degree helix angle promotes smooth chip flow and reduces cutting forces
• Weldon flat shank for secure, anti-pullout retention in set-screw holders
• Center-cutting capable, allowing plunge entry into workpiece
• Bright, uncoated finish suitable for a broad material range including non-ferrous and high-temp alloys

Compatibility

Designed for use in standard end mill holders and Weldon-style set-screw toolholders accepting a 0.625-inch shank diameter. Compatible with vertical and horizontal CNC machining centers running right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat against the set screw fully before torquing the holder to prevent axial pullout. Verify runout with a dial indicator after installation and before initiating a cutting cycle.
