Sgs 00312 Square End Mill 1/64 in 2 Flute Solid Carbide

Product Description

The SGS 00312 is a solid carbide square end mill designed for high-precision milling in tight-tolerance applications. With a 1/64 inch (0.0160 inch) cutting diameter, a 0.024 inch length of cut, and a 1/8 inch straight cylindrical shank, this stub-length tool is built for controlled material removal in confined geometries. The micrograin carbide construction provides edge hardness and wear resistance suited to ferrous and non-ferrous materials. At 1-1/2 inches overall length, the compact form factor minimizes deflection and vibration during cutting operations. Licensed machinists, tool-and-die shops, and precision CNC operators are the primary users of this class of end mill.

The 00312 is suited for slotting, profiling, and plunge-cutting operations on CNC machining centers and manual mills where fine detail work at very small diameters is required. The stub length and 0.024 inch LOC make it well matched to shallow pocket milling and surface finishing passes on hardened or difficult materials. It is commonly used in mold making, medical device machining, and electronics component fabrication where dimensional accuracy at sub-1/16 inch scales is critical.

Key Features

• Micrograin solid carbide construction for edge retention and rigidity at small diameters
• 2-flute, right-hand spiral design with right-hand cut for standard CNC spindle compatibility
• Centercutting geometry allows direct plunge entry without pre-drilling
• 30-degree helix angle balances chip evacuation with cutting stability
• Stub length form factor reduces deflection and improves rigidity in tight setups
• Uncoated finish suitable for use with cutting fluids across a range of workpiece materials

Compatibility

Designed as an OEM-style solid carbide square end mill in the SGS Series 1620 line, compatible with standard 1/8 inch straight-bore tool holders and collets on CNC machining centers and manual milling machines.

Installation Notes

Installation of small-diameter end mills requires a clean, properly sized collet or end mill holder to prevent runout and tool pullout during cutting. Always power down and lock out the spindle before tool changes. Confirm holder bore diameter matches the 1/8 inch shank before clamping. At diameters below 1/16 inch, feed and speed parameters should be dialed conservatively on initial passes to avoid breakage, and tool reach should be minimized to the shortest extension the setup allows.
