Sgs 32778 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The SGS 32778 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal applications. With a 0.5 inch mill diameter, a 0.12 inch corner radius, and three right-hand spiral flutes, this tool delivers controlled roughing cuts with reduced edge chipping on aluminum, brass, copper, and similar materials. The S-Carb 43LC series geometry features a high helix angle and coarse pitch, promoting efficient chip evacuation during aggressive cuts. The bright uncoated finish is well suited to non-ferrous workpieces where coating buildup or chemical reactivity could be a concern. Licensed machinists and CNC tooling technicians typically select this end mill for production milling operations where extended reach is required.

This end mill fits into standard straight-shank end mill toolholders with a 0.5 inch bore. It is built for single-end use and configured for extended reach applications, with a 3.375 inch reach length that allows access into deeper pockets or stepped features without interference from the shank. The 5/8 inch length of cut and 6 inch overall length make it appropriate for CNC machining centers and manual knee mills working with non-ferrous metals in both job shop and production environments. The micrograin carbide substrate supports the precise tolerances required for finish-quality corner profiles.

Key Features

• 0.12 inch corner radius with a tolerance of -0.0020 to 0.0000 inches for consistent edge geometry
• Solid micrograin carbide construction for rigidity and wear resistance in non-ferrous cutting
• Extended reach design with 3.375 inch reach length and 0.48 inch neck diameter
• High helix, coarse pitch, right-hand spiral flutes promote efficient chip evacuation during roughing
• Bright uncoated finish - no coating interaction with aluminum or other non-ferrous metals
• Straight-cylindrical shank with h6 tolerance for precise toolholder fit and runout control

Compatibility

Designed for use with standard end mill toolholders accepting a 0.5 inch straight-cylindrical shank. Intended for machining non-ferrous metals including aluminum, brass, and copper alloys.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC tooling technician with the spindle fully stopped and the machine in a safe, locked-out state. Seat the shank fully in the toolholder and torque the retention hardware according to the toolholder manufacturer specifications. Inspect the corner radius and cutting edges for chips or damage before each use. Confirm spindle direction and feed-rate parameters in the CNC program before initiating a cut.
