Sgs 35640 Corner Radius End Mill 3/4 in 3 Flute Carbide

Product Description

The SGS 35640 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal applications. It features a 3/4-inch mill diameter, a 2-1/4-inch length of cut, and a 0.2500-inch corner radius that helps reduce stress concentrations and extend tool life in milled profiles. The three-flute, right-hand spiral geometry combined with a 38-degree high helix angle promotes efficient chip evacuation and smooth cutting action. This is a single-end, straight-shank tool with an uncoated bright finish, suited for use in end mill toolholders on CNC machining centers and manual mills.

This end mill is intended for roughing operations in non-ferrous metals such as aluminum, copper, and brass. The coarse pitch and high helix design support aggressive material removal rates while maintaining workpiece surface quality. With a 5-inch overall length and a 3/4-inch shank diameter, it fits standard end mill toolholders and is appropriate for setups where extended reach is not required. Machinists and CNC operators working in job shops, production facilities, or aerospace component manufacturing will find this tool suited to slotting, profiling, and peripheral milling operations on non-ferrous stock.

Key Features

• 0.2500-inch corner radius reduces edge chipping and stress risers in milled profiles
• Solid carbide construction provides rigidity and wear resistance in non-ferrous metal cuts
• 38-degree high helix angle promotes efficient chip evacuation and reduced cutting forces
• Three right-hand spiral flutes with coarse pitch support roughing material removal rates
• Bright/uncoated finish - no coating buildup issues when running non-ferrous materials
• Straight-cylindrical shank fits standard end mill toolholders without adaptation

Compatibility

Designed for use with standard end mill toolholders. Optimized for non-ferrous metal workpiece materials per Series 43CR specifications. Not center-cutting; not suited for plunge entry without pre-drilled clearance.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the toolholder. Verify toolholder bore and collet size match the 3/4-inch shank diameter before clamping. Confirm runout is within acceptable limits after seating to protect the corner radius tolerance of +0.00000 to -0.00200 inches.
