Sgs 34308 Corner Radius End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The SGS 34308 is a solid carbide corner radius end mill engineered for high-performance milling in demanding machining environments. It features a 3/4 inch cutting diameter, a 1-5/8 inch length of cut (LOC), and a 0.03 inch corner radius that reduces stress concentrations at part edges and extends tool life compared to sharp-corner geometry. Three right-hand spiral flutes with a 38-degree helix angle promote efficient chip evacuation and smooth cutting action. The tool is centercutting, allowing plunge entry into workpiece material. A TiB2 (titanium diboride) coating provides added hardness and lubricity at the cutting edge. Overall length is 4 inches with a 3/4 inch shank diameter. This end mill is installed and operated by machinists and CNC tooling professionals working in production or job-shop settings.

The SGS 34308 belongs to the S-Carb 43CB series, designed for regular-length milling operations in ferrous and non-ferrous materials where a corner radius profile is required. Typical applications include slot milling, peripheral milling, and profiling passes where a blended corner radius is specified on the finished part. The right-hand cutting direction and right-hand flute direction make this tool compatible with standard CNC machining center spindle configurations. It is suited for use in both roughing and finishing passes where the 0.03 inch radius provides edge protection without significantly altering the part profile.

Key Features

• 0.03 inch corner radius reduces edge chipping and stress risers on finished parts
• Three right-hand spiral flutes with 38-degree helix for efficient chip removal
• TiB2 coating increases surface hardness and reduces friction at the cutting edge
• Centercutting design permits direct plunge entry without pilot drilling
• Solid carbide construction provides rigidity and dimensional stability under load
• Regular-length geometry suits standard depth-of-cut applications on most CNC platforms

Compatibility

Designed as an OEM-style replacement and standard production tooling option for CNC machining centers and manual mills accepting a 3/4 inch straight shank end mill in the S-Carb 43CB series.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe tool-change state before installing or removing the end mill. Use a properly sized collet or end mill holder rated for the 3/4 inch shank diameter and torque the retention hardware according to the toolholder manufacturer specifications. Verify runout with a dial indicator after installation before initiating a cutting cycle.
