Sgs 34859 Square End Mill 1/4 Inch 3 Flute Solid Carbide

Product Description

The SGS 34859 is a solid carbide square end mill designed for precision milling in non-ferrous metal applications. It features a 1/4 inch cutting diameter, a 1/2 inch length of cut, and a 2-1/2 inch overall length with a 1/4 inch straight cylindrical shank. The three-flute geometry and 38-degree helix angle promote efficient chip evacuation and smooth cutting action. A TiB2 finish adds surface hardness and reduces built-up edge when cutting aluminum and other non-ferrous materials. This tool is center-cutting, allowing it to plunge directly into a workpiece. It is suited for machinists and tool-and-die professionals running CNC mills or manual knee mills.

The SGS 34859 is intended for milling operations in non-ferrous metals such as aluminum, brass, and copper. Its regular-length geometry fits standard toolholding in both vertical machining centers and manual mills. The right-hand cut and right-hand spiral flute configuration match conventional spindle rotation for typical setups. This end mill works in slotting, profiling, and light plunge applications where a center-cutting tool is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous applications
• TiB2 finish reduces friction and built-up edge when cutting aluminum and similar materials
• 38-degree helix angle promotes efficient chip flow and smooth cutting action
• Center-cutting design allows direct plunge entry without a pre-drilled pilot hole
• Three-flute spiral geometry balances material removal rate with surface finish quality
• Right-hand cut and right-hand flute for standard CNC and manual mill spindle configurations

Compatibility

Designed as a Series 43 solid carbide square end mill with a 1/4 inch straight cylindrical shank fitting standard collets and toolholders rated for 1/4 inch shank tooling. Intended for use in non-ferrous metal milling applications.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear and reduce surface finish quality.
