Sgs 00323 Square End Mill 0.027 in 2 Flute Solid Carbide

Product Description

The SGS 00323 is a solid carbide square end mill designed for precision milling of small-diameter features in metal, composite, and hard material applications. With a 0.027-inch cutting diameter and a 0.041-inch length of cut, this tool is built for micro-machining work where dimensional accuracy is critical. The 1/8-inch shank diameter and 1-1/2-inch overall length make it compatible with standard collet systems on CNC mills and manual machining centers. The micrograin carbide substrate provides the rigidity and edge retention needed at these small diameters. This tool is installed and used by machinists, toolroom technicians, and CNC programmers working in precision manufacturing environments.

The SGS 00323 is suited for stub-length milling operations requiring tight tolerances in small-feature work. Its centercutting geometry allows plunge entry, expanding its use to slot milling, pocketing, and contour work. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining setups. The 30-degree helix angle promotes smooth chip evacuation in shallow-cut applications. This tool fits production and prototype machining across industries including aerospace, medical device, and electronics manufacturing where fine detail and tight diameter tolerances are required.

Key Features

• 0.027-inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0008 inches for precise fits
• Centercutting design allows direct plunge entry into workpiece material
• Micrograin solid carbide construction for edge retention and rigidity at micro diameters
• 30-degree helix angle with spiral flute geometry for controlled chip flow
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Stub length classification with 0.041-inch length of cut for maximum tool stiffness

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills equipped with 1/8-inch collet or tool holder systems accepting standard shank end mills.

Installation Notes

Installation of small-diameter end mills should be performed by qualified machinists familiar with collet torque requirements and runout specifications for micro tooling. Ensure the spindle and collet are clean and free of chips before seating the shank. At diameters below 0.030 inches, tool deflection and runout are critical factors — verify holder runout with a dial indicator before cutting. Follow machine tool manufacturer guidelines and applicable shop safety procedures when handling and storing carbide cutting tools.
