Sgs 35289 Square End Mill 1/2 in 2 Flute Solid Carbide

Product Description

The SGS 35289 is a solid carbide square end mill designed for precision milling of non-ferrous metals and similar materials. With a 0.5000 inch mill diameter, a 1 inch length of cut, and a 3 inch overall length, this tool delivers consistent material removal in light to moderate machining applications. The 2-flute geometry and 30-degree helix angle promote efficient chip evacuation, reducing heat buildup and improving surface finish on softer workstocks. The uncoated solid carbide construction provides rigidity and wear resistance suited to demanding production environments. Right-hand cut and right-hand flute orientation follow standard CNC and manual milling conventions. Centercutting capability allows plunge entry without a pre-drilled pilot hole.

The SGS 35289 is intended for use in CNC machining centers, knee mills, and manual milling machines where non-ferrous metals such as aluminum, brass, and copper are the primary workpiece materials. The straight-cylindrical shank seats cleanly in standard ER collets, end mill holders, and hydraulic chucks with a 0.5000 inch bore. The regular-length profile suits general-purpose pocket milling, slotting, profiling, and contouring operations where extended reach is not required. Machinists working in job shop, production, and toolroom settings will find this a reliable general-purpose cutter for everyday non-ferrous work.

Key Features

• 0.5000 inch mill diameter with tight tolerance of +0.000 / -0.002 inches for precise fitment in programmed toolpaths
• Solid carbide construction for rigidity and long tool life in non-ferrous applications
• 2-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute orientation compatible with standard machine spindle rotation
• Straight-cylindrical shank with tolerance of +0.00000 / -0.00043 inches for secure tool holding

Compatibility

Designed as an OEM-style replacement and standard-use solid carbide square end mill in the SGS Series 52 line, suited for non-ferrous metal milling applications with any machine tool accepting a 0.5000 inch straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout verification. Confirm spindle is fully stopped and machine is in an e-stop or powered-down state before changing tooling. Seat the shank fully in the collet or tool holder to the recommended engagement depth and torque the retention hardware to the tool holder specification. Verify runout with a dial indicator before committing to a full-depth cut, particularly in tight-tolerance finishing passes.
