Sgs 34781 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The SGS 34781 is a solid carbide corner radius end mill designed for material removal in non-ferrous metal machining applications. It features a 1/2 inch mill diameter, a 1-1/4 inch length of cut, and a 0.09 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. With 3 helical flutes in a right-hand cutting direction and a high-helix configuration, the 34781 is built for roughing passes where chip evacuation and edge strength matter. This is a single-end tool with a straight cylindrical shank and a 3-1/4 inch overall length.

The SGS 34781 is intended for use in CNC machining centers and manual mills working with non-ferrous metals such as aluminum, brass, and copper alloys. The coarse pitch flute geometry supports aggressive stock removal in these materials. It seats in standard end mill holders with a 1/2 inch bore. The uncoated bright finish is suited to applications where lubricity from a coating is not required or where coolant is applied externally. It is appropriate for production shops and job shops running non-ferrous programs on vertical or horizontal machining centers.

Key Features

• 0.09 inch corner radius reduces edge chipping and stress risers during roughing
• Solid carbide construction provides rigidity and wear resistance in non-ferrous cutting
• 3 right-hand helical flutes with coarse pitch for efficient chip evacuation
• High helix style promotes smooth cutting action and reduced cutting forces
• Straight cylindrical shank with h6 tolerance for precise holder fit
• Single-end design with 3-1/4 inch overall length for standard reach applications

Compatibility

Designed for use with standard end mill holders accepting a 1/2 inch straight-cylindrical shank. Optimized for non-ferrous metal workpiece materials per Series 43CR application specifications.

Installation Notes

Installation is performed by a machinist or CNC setup technician. The machine spindle must be fully stopped and de-energized before changing tooling. Seat the shank fully into the end mill holder and torque the set screw or collet nut to the holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear on this uncoated tool.
