Sgs 00311 Square End Mill 0.015 in 2 Flute Solid Carbide

Product Description

The SGS 00311 is a solid carbide square end mill designed for precision milling in tight tolerances and small-feature applications. With a 0.015 inch cutting diameter and a 0.023 inch length of cut, this stub-length tool is built for micro-machining work where rigidity and accuracy are critical. The micrograin carbide substrate supports sharp edges and consistent performance in ferrous and non-ferrous materials. A 30-degree helix angle promotes chip evacuation while maintaining cutting stability. This tool is used by machinists and tool-and-die professionals running CNC mills and machining centers where fine detail and minimal runout are required.

This end mill is suited for small-feature profiling, slotting, and contouring operations in production and prototype machining environments. Its stub length classification reduces deflection during cuts, making it a practical choice for high-precision work in mold making, medical component manufacturing, and aerospace part production. The 1/8 inch straight-cylindrical shank fits standard collet toolholding systems commonly found in vertical machining centers and CNC routers.

Key Features

• 0.015 inch cutting diameter with a tight mill diameter tolerance of +0.0000 / -0.0008 inches
• Micrograin solid carbide construction for edge sharpness and wear resistance
• 2-flute, spiral flute geometry with a 30-degree helix angle for efficient chip removal
• Centercutting design allows plunge entry into workpiece material
• Right-hand cut and right-hand flute configuration for standard CNC spindle operation
• Uncoated finish — suitable for use with cutting fluids on a range of base materials

Compatibility

Designed as an OEM-style replacement and direct-fit tool for CNC machining centers and manual mills equipped with 1/8 inch straight-shank collet toolholding systems. Part of the SGS Series 1620 stub-length square end mill family.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholding torque and runout verification. Ensure the spindle and collet are clean and free of debris before seating the shank. Verify runout with a dial indicator before beginning cuts, as micro-diameter end mills are sensitive to even small amounts of collet or spindle runout. Do not exceed the recommended depth of cut for stub-length tools of this diameter.
