Sgs 34721 Square End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The SGS 34721 is a solid carbide square end mill designed for precision milling of non-ferrous metals. It features a 3/4-inch cutting diameter, a 1-5/8-inch length of cut, and a 4-inch overall length, making it a regular-length tool suited for general-purpose slotting, profiling, and peripheral milling operations. The three-flute geometry balances chip evacuation with edge strength, while the 38-degree helix angle promotes efficient cutting action in aluminum, brass, copper, and similar materials. This tool is installed and used by machinists and tool-and-die professionals operating CNC machining centers and manual mills.

The SGS 34721 is intended for milling non-ferrous metals, identified by primary workpiece material code N. Its right-hand cut and right-hand spiral flute configuration suits standard CNC and manual spindle setups. The straight-cylindrical shank accepts standard collet chucks and end mill holders sized for 3/4-inch tooling. This is a single-end, uncoated tool in the SGS Series 43 line, appropriate for shops that run aluminum-intensive work or require a dedicated non-ferrous end mill for finishing and roughing passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous applications
• 3-flute design balances chip clearance and cutting edge support
• 38-degree helix angle promotes smooth cutting action and reduced chatter
• Right-hand cut, right-hand flute spiral for standard spindle compatibility
• Uncoated finish suited for non-ferrous metals where coating adhesion is not required
• Tight diameter tolerances: +0.00000 / -0.00051 inches on both mill and shank diameters

Compatibility

Designed for use in standard 3/4-inch collet chucks, shrink-fit holders, and end mill holders on CNC machining centers and manual knee mills. Primary workpiece material designation is non-ferrous metal (code N), including aluminum, brass, and copper alloys.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling specifications. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the straight-cylindrical shank to the full recommended engagement depth in the holder to minimize runout and tool pull-out risk. Verify holder and collet cleanliness before securing the tool.
