Sgs 39301 Square End Mill 1/64 in 2 Flute Solid Carbide

Product Description

The SGS 39301 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.0156-inch (1/64 inch) mill diameter and a 0.0313-inch (1/32 inch) length of cut, this is a micro end mill built for fine-detail work in tight geometries. The 1/8-inch straight-cylindrical shank and 1-1/2-inch overall length provide a rigid, stable setup in standard collets and tool holders. A titanium nitride (TiN) finish improves surface hardness and wear resistance. Machinist and CNC operators working on precision components rely on this tool for accurate, repeatable cuts.

This end mill is suited for milling operations on a broad range of workpiece materials, including cast iron, non-ferrous metals, steel, stainless steel, heat-resistant alloys, and non-metallic materials, corresponding to material codes H, K, M, N, P, and S. The centercutting design allows for plunge entry, expanding its versatility in slotting and pocketing operations. It is appropriate for both manual mill setups and CNC machining centers where micro-diameter tooling is required.

Key Features

• 0.0156-inch (1/64 inch) mill diameter for fine micro-milling applications
• Solid carbide micrograin construction for rigidity and edge retention at small diameters
• TiN coating enhances wear resistance and reduces friction at the cutting edge
• Centercutting capable — supports plunge milling and full-slot entry
• 2-flute, right-hand cut with right-hand spiral flute and 30-degree helix angle
• Mill diameter tolerance of +0.000 / -0.002 inches ensures consistent sizing

Compatibility

Designed as a regular-length, straight-shank micro end mill compatible with 1/8-inch collets and tool holders on standard vertical milling machines and CNC machining centers. Suited for workpiece materials classified under codes H, K, M, N, P, and S as specified by SGS Series 3 tooling standards.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked. Secure the 1/8-inch shank in a properly sized collet or end mill holder, verifying runout before commencing cuts, as runout is especially critical at micro diameters. Do not exceed the rated length of cut of 0.0313 inches for axial engagement. Follow your machine tool manufacturer guidelines for speeds and feeds appropriate to this diameter and workpiece material.
