Sgs 34704 Square End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The SGS 34704 is a solid carbide square end mill designed for precision milling in non-ferrous metals and similar materials. With a 0.25-inch cutting diameter, a 0.75-inch length of cut, and a 3-flute spiral geometry, this end mill delivers clean material removal and accurate edge definition in CNC machining centers and manual mills. The 38-degree helix angle promotes efficient chip evacuation, reducing heat buildup at the cutting edge. The uncoated carbide construction suits applications where coating reactivity is a concern. This tool is installed and operated by machinists and CNC programmers in job shop, production, and maintenance environments.

The SGS 34704 is suited for light to medium milling operations in non-ferrous metals such as aluminum, brass, copper, and similar materials designated under the N workpiece material code. It fits a standard 0.25-inch straight-cylindrical shank, compatible with collet chucks, end mill holders, and shrink-fit tooling common on CNC machining centers and manual knee mills. The regular-length configuration keeps overhang minimal, which supports rigidity during slotting, profiling, and pocketing operations.

Key Features

• 0.25-inch cutting diameter with tight mill diameter tolerance of +0.00000/-0.00035 inches
• 3-flute spiral flute design for efficient chip flow in non-ferrous materials
• 38-degree helix angle promotes chip evacuation and reduces cutting heat
• Uncoated solid carbide construction for use in non-ferrous and reactive-material applications
• Right-hand cut, right-hand flute orientation — standard for conventional CNC setups
• Non-center-cutting design — not suitable for direct plunge entry

Compatibility

Designed as an OEM-style solid carbide end mill fitting standard 0.25-inch collet and end mill holder systems on CNC machining centers and manual mills used in non-ferrous metal machining applications.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Seat the shank fully into the holder and torque the retention mechanism to the toolholder manufacturer's specification before operation. Because this is a non-center-cutting end mill, ramping or helical interpolation entry strategies must be used rather than direct axial plunge. Inspect the cutting edges for chipping before each use and replace the tool if edge integrity is compromised.
