Sgs 34309 Corner Radius End Mill 1in 3 Flute Solid Carbide

Product Description

The SGS 34309 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. Built to Series S-Carb 43CB standards, it features a 1 inch cutting diameter, a 2 inch length of cut, and a 0.03 inch corner radius that reduces edge chipping and extends tool life on profiling passes. The 4.5 inch overall length and 1 inch shank diameter suit it for standard toolholders in vertical and horizontal machining centers. A TiB2 (titanium diboride) coating adds surface hardness and reduces heat buildup at the cutting edge. This tool is intended for use by machinists and CNC operators in job shop and production environments.

The SGS 34309 fits milling applications where a blended corner radius is required to avoid sharp corner stress concentrations in the workpiece. The 3-flute, right-hand spiral geometry with 38-degree helix promotes efficient chip evacuation in slotting and peripheral milling. The centercutting design allows plunge entry without a pre-drilled hole. Regular length configuration makes it a practical choice for general-purpose profiling, contouring, and pocketing operations where extended reach is not needed.

Key Features

• 0.03 inch corner radius reduces stress concentration and edge chipping on workpiece corners
• TiB2 coating improves surface hardness and heat resistance at the cutting edge
• 3-flute right-hand spiral with 38-degree helix for efficient chip evacuation
• Centercutting geometry allows direct plunge entry
• Solid carbide construction provides rigidity and dimensional stability
• Series S-Carb 43CB design built to consistent OEM geometry standards

Compatibility

Designed for use in standard toolholders accepting a 1 inch shank diameter. Compatible with vertical and horizontal machining centers using ER, shrink-fit, or hydraulic chuck toolholding systems that accommodate a 1 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before inserting or removing the tool. Seat the shank to the full recommended grip length in the toolholder to minimize runout. Verify tool length offset and corner radius compensation settings in the CNC control before running the first part.
