Sgs 34773 Corner Radius End Mill 1/4 in 3 Flute Carbide

Product Description

The SGS 34773 is a solid carbide corner radius end mill designed for precision material removal in non-ferrous metal applications. It features a 1/4 inch mill diameter with a 0.01 inch corner radius, 3 right-hand helical flutes, and a coarse pitch configuration suited for roughing operations. The high helix angle promotes efficient chip evacuation, which is critical when cutting aluminum, brass, copper, and similar non-ferrous workpiece materials. The tool is uncoated and single-end, with a 2.5 inch overall length and a 3/4 inch length of cut. It is sized for use with standard end mill holders and is appropriate for CNC machining centers and manual mills operated by machinists and tool-and-die professionals.

The SGS 34773 Series 43CR is intended for non-ferrous metal cutting in both production and job-shop environments. Its corner radius geometry reduces edge chipping and stress concentration at the cutting corner, making it suitable for finishing passes with a defined radius or for light profiling and slotting in softer materials. The 1/4 inch shank diameter fits standard end mill holders and collet chucks. This tool is appropriate for applications where a small corner break is required on milled features without a full ball-end profile.

Key Features

• Solid carbide construction provides rigidity and wear resistance in non-ferrous cutting applications
• 0.01 inch corner radius reduces edge chipping and stress at the cutting corner
• 3 right-hand helical flutes with high helix angle for efficient chip evacuation
• Coarse pitch, roughing-style geometry supports aggressive material removal rates
• Uncoated bright finish suited for non-ferrous metals where coating adhesion is not required
• Straight cylindrical shank with h6 tolerance for accurate seating in end mill holders

Compatibility

Designed for use with standard end mill holders accepting a 1/4 inch straight cylindrical shank. Intended for non-ferrous metal workpiece materials as indicated by primary material code N.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and locked out per applicable safety procedures. Secure the shank fully within the holder to the recommended gauge line depth before tightening. Verify runout with a dial indicator before cutting, as excessive runout will accelerate wear and degrade corner radius accuracy. Do not use this tool on ferrous materials, as it is rated for non-ferrous applications only.
