Sgs 34662 Square End Mill 0.25in 2 Flute Solid Carbide

Product Description

The SGS 34662 is a solid carbide square end mill designed for precision material removal in light machining and finishing operations. It features a 0.25 inch cutting diameter, a 0.75 inch length of cut, and a 2-flute spiral flute geometry with a 35-degree helix angle. The TiB2 (titanium diboride) coating reduces friction and extends tool life on non-ferrous workpieces. Centercutting capability allows plunge cuts as well as conventional peripheral milling. This end mill ships as a single unit and is suited for use by machinists and tool-and-die professionals working on CNC mills and manual knee mills.

The SGS 34662 is optimized for non-ferrous metals, including aluminum, brass, copper, and similar materials where chip evacuation and surface finish are critical. With a 0.25 inch straight-cylindrical shank and a 2.5 inch overall length, it fits standard ER collet chucks and end mill holders common in job shop and production environments. The regular length profile keeps deflection low during shallow-to-mid depth passes on non-ferrous stock.

Key Features

• 0.25 inch cutting diameter with a tight mill diameter tolerance of -0.0001 to -0.0004 inches for close-tolerance work
• TiB2 finish reduces built-up edge on non-ferrous materials
• 35-degree helix angle promotes smooth chip flow and improved surface finish
• Centercutting design enables direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand spiral flute for standard CNC and manual mill setups
• Solid carbide construction provides rigidity and wear resistance compared to HSS alternatives

Compatibility

Designed as an OEM-style replacement or direct-fit tool for standard 0.25 inch straight-shank end mill holders and ER collet chucks used in CNC machining centers and manual mills targeting non-ferrous metal applications.

Installation Notes

Installation is performed by qualified machinists following standard tooling change procedures. Ensure the machine spindle is fully stopped and locked out before changing end mills. Verify collet or holder bore is clean and free of chips before seating the shank. Shank diameter tolerance is +0.00000 to -0.00035 inches, so use a properly sized, undamaged collet to ensure concentricity and prevent runout.
