Sgs 00618 Square End Mill 0.04 in 4 Flute Solid Carbide

Product Description

The SGS 00618 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 0.04-inch cutting diameter and a 0.32-inch length of cut, this tool is built for tight-tolerance work in small-feature applications. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting performance. The micrograin carbide construction delivers rigidity and wear resistance in demanding cuts. It is sold individually and installed in compatible milling machine spindles by machinists and tool-and-die professionals.

This end mill is suited for small-bore slotting, profiling, and pocketing operations where dimensional accuracy is critical. The bright, uncoated finish makes it appropriate for use in a range of general-purpose materials. Its extended-length classification, 2.5-inch overall length, and 0.125-inch straight cylindrical shank allow it to reach into features that standard-length tools cannot access. The centercutting capability enables plunge entry where the application requires it.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• Four flutes with right-hand spiral and 30-degree helix for efficient chip flow
• Centercutting design allows direct plunge entry
• Bright/uncoated finish suitable for general-purpose milling applications
• Extended length at 2.5 inches overall for improved reach into deep features
• Mill diameter tolerance of +0.000 to -0.001 inches for tight-tolerance fitment

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard milling machine spindles accepting a 0.125-inch straight cylindrical shank.

Installation Notes

Installation is performed by machinists using a compatible collet or end mill holder rated for the 0.125-inch shank diameter. Ensure the machine spindle and tool holder are clean and free of debris before seating the shank. Disengage and lock out all power to the machine before changing tooling. Verify runout after installation to confirm concentricity within acceptable limits for the application.
