Sgs 39345 Square End Mill 23/64 in 2 Flute Solid Carbide

Product Description

The SGS 39345 is a solid carbide square end mill designed for precision milling in a wide range of metalworking and machining applications. It features a 23/64-inch (0.3594 inch) cutting diameter, a 1-inch length of cut, and a 3/8-inch straight cylindrical shank. The 2-flute, spiral-flute geometry with a 30-degree helix angle promotes efficient chip evacuation. A TiN finish provides surface hardness and wear resistance. At 2-1/2 inches overall length, this is a standard-reach tool suited for general-purpose slot milling, profiling, and peripheral cuts in a variety of workpiece materials.

This end mill is rated for use across multiple workpiece material categories including cast iron, non-ferrous metals, steel, stainless steel, high-temperature alloys, and non-metallic materials, corresponding to ISO material groups H, K, M, N, P, and S. It is centercutting, allowing plunge entry directly into the workpiece. Right-hand cut and right-hand flute configuration make it compatible with standard CNC machining centers and manual milling machines running conventional spindle rotation. The regular-length classification suits most common depth-of-cut requirements without requiring extended-reach tooling.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in demanding cuts
• TiN (Titanium Nitride) finish for improved surface hardness and tool life
• Centercutting design allows direct plunge milling without pre-drilling
• 30-degree helix angle with spiral flute for efficient chip evacuation
• Right-hand cut and right-hand flute for use with standard spindle rotation
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as a Series 3 SGS solid carbide square end mill suitable for use in CNC machining centers and manual milling machines accepting a 3/8-inch straight cylindrical shank, across ISO workpiece material groups H, K, M, N, P, and S.

Installation Notes

This tool is installed by a machinist or CNC operator using a compatible collet or end mill holder rated for a 3/8-inch shank diameter. Ensure the spindle and all machine axes are fully stopped and locked out before changing tooling. Verify runout and tool projection before beginning a cut. Follow the machine manufacturer and tooling manufacturer feed and speed recommendations for the specific workpiece material and depth of cut.
