Sgs 34681 Square End Mill 1/2 in 2 Flute Solid Carbide

Product Description

The SGS 34681 is a solid carbide square end mill designed for high-performance milling in non-ferrous metal applications. Built to Series 47E specifications, this centercutting tool features a 0.5 inch diameter, a 0.625 inch length of cut, and a 6 inch overall length with a 0.5 inch straight cylindrical shank. The TiB2 (titanium diboride) coating improves lubricity and reduces built-up edge when cutting aluminum, copper, brass, and similar materials. The 35-degree helix angle and two spiral flutes promote efficient chip evacuation, making this end mill well suited for slotting, profiling, and plunge operations in soft and gummy metals.

The SGS 34681 is intended for use on CNC machining centers and manual mills where non-ferrous metals are the primary workpiece material. The extended reach design, with a 3.375 inch reach length, provides clearance for deeper pockets and stepped features without requiring a longer tool assembly. Right-hand cut and right-hand flute geometry follow standard convention, making this a direct fit for conventional spindle setups. It is a regular-length tool suited to everyday shop production work.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous cutting
• TiB2 coating reduces friction and resists material adhesion on aluminum and soft metals
• 35-degree helix angle promotes aggressive chip evacuation in two-flute spiral configuration
• Centercutting design allows direct plunge entry without pre-drilling
• Extended reach at 3.375 inches for deep-pocket and clearance applications
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill setups

Compatibility

Designed as a Series 47E solid carbide square end mill optimized for non-ferrous metals (material code N), including aluminum, copper, brass, and similar alloys. Straight cylindrical shank accepts standard 1/2 inch collets and end mill holders.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Ensure the collet or end mill holder is clean and free of chips before seating the shank. Torque retention hardware to shop standards using calibrated tooling — do not exceed equipment manufacturer torque specifications. Verify runout with a dial indicator after clamping before beginning any cut.
