Sgs 00398 Square End Mill 1/32 in 4 Flute Solid Carbide

Product Description

The SGS 00398 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built to Series 1820 specifications, this stub-length tool features a 1/32 inch (0.0313 inch) cutting diameter and a 3/64 inch (0.0469 inch) length of cut, making it well suited for fine detail work in tight geometries. With four flutes and a 30-degree right-hand helix, it delivers efficient chip evacuation and smooth cutting action. The micrograin carbide construction provides wear resistance and edge stability in demanding materials. Licensed machinists and CNC operators are the primary installers and users of this tooling.

This end mill is intended for use in CNC machining centers, manual mills, and precision grinding setups where small-diameter cutting is required. The stub length profile and straight cylindrical shank make it compatible with standard collet chuck systems. Its centercutting capability allows for plunge milling as well as peripheral cuts. Typical applications include slotting, contouring, and profiling operations in ferrous and non-ferrous materials at the micro scale.

Key Features

• Micrograin solid carbide construction for edge retention and wear resistance
• Four flutes with 30-degree right-hand helix for efficient chip evacuation
• Centercutting design allows plunge and peripheral milling
• Stub length profile for rigidity in tight-clearance applications
• Bright/uncoated finish suitable for use with or without coolant
• Straight cylindrical shank fits standard collet and end mill holders

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard collet chuck systems and end mill holders accepting a 1/8 inch shank diameter.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Torque the collet nut or set screw according to the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning production cuts, as small-diameter carbide tooling is sensitive to misalignment and can fracture under lateral load.
