Sgs 34303 Corner Radius End Mill 3/4 in 3 Flute Carbide

Product Description

The SGS 34303 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/4 inch cutting diameter, a 1-5/8 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life compared to a sharp-corner geometry. With 3 flutes and a 38-degree helix angle, the tool balances chip evacuation with cutting stability. The bright uncoated finish suits applications where coating buildup could interfere with tolerances or where re-sharpening frequency is high. Overall length is 4 inches with a 3/4 inch shank diameter.

This end mill is suited for milling ferrous and non-ferrous materials in job shop, die and mold, and general machining environments. The center-cutting design allows plunge entry, making it versatile for slot milling, peripheral milling, and ramping operations. It belongs to the SGS S-Carb 43CB series, which is engineered for rigidity and consistent performance in regular-length milling setups on CNC vertical machining centers and manual knee mills alike.

Key Features

• 0.03 inch corner radius reduces edge chipping and stress risers in the workpiece
• 3-flute, 38-degree right-hand helix promotes efficient chip evacuation
• Solid carbide construction provides rigidity and wear resistance
• Center-cutting geometry enables direct plunge entry without pre-drilling
• Bright uncoated finish supports use across a wide range of base materials and allows easy re-sharpening
• Regular length profile suits standard reach applications without overhang-related deflection

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 3/4 inch collets, end mill holders, and hydraulic chucks accepting a 3/4 inch straight shank; part of the SGS S-Carb 43CB series.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify holder runout with a dial indicator before committing to finish cuts, as excessive runout accelerates corner radius wear. Follow the machine tool manufacturer torque specifications for the collet nut or set screw — do not overtighten, as carbide shanks can fracture under excessive clamping force.
