Sgs 34825 Square End Mill 1/4 in 3 Flute Solid Carbide

Product Description

The SGS 34825 is a solid carbide square end mill designed for precise milling operations in non-ferrous metals and similar materials. With a 0.250 inch mill diameter, a 1 inch length of cut, and a 3 inch overall length, this tool delivers consistent material removal in a compact, regular-length profile. The 3-flute geometry paired with a 38-degree helix angle balances chip evacuation and surface finish, making it a practical choice for slotting, profiling, and pocketing operations on CNC machining centers and manual mills. It is uncoated and centercutting, allowing plunge cuts as well as conventional side milling.

This end mill is suited for machining non-ferrous metals including aluminum, brass, copper, and similar N-group workpiece materials. The straight cylindrical shank at 0.250 inches fits standard ER collets and end mill holders. Its regular length classification makes it appropriate for general-purpose setups where rigidity and chatter resistance are priorities. Machinists and CNC programmers in job shops, production facilities, and toolrooms will find this a reliable choice for everyday non-ferrous cutting applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous applications
• 3-flute design with 38-degree helix angle for efficient chip evacuation and smooth finish
• Centercutting geometry allows plunge entry without a pre-drilled pilot hole
• Right-hand cut with right-hand spiral flute, compatible with standard spindle rotation
• Mill diameter tolerance of +0.00000 to -0.00035 inches for close-tolerance fitment
• Straight cylindrical shank with h6 tolerance for secure, concentric clamping in collet chucks

Compatibility

Designed for use in standard 1/4 inch ER collets, end mill holders, or hydraulic chucks on CNC machining centers and manual knee mills. Primary workpiece material classification is non-ferrous metal (Material Code N). Series 43 designation per SGS tooling lineup.

Installation Notes

Installation and tool changes should be performed with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Ensure the collet or tool holder bore is clean and free of chips before seating the shank. Verify runout after installation using a dial indicator before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish. Consult your machine tool manufacturer and shop safety guidelines for speeds, feeds, and coolant recommendations appropriate to the workpiece material.
