Sgs 35678 Corner Radius End Mill 3/8 in 3 Flute Carbide

Product Description

The SGS 35678 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal machining applications. With a 3/8 inch mill diameter and a 0.06 inch corner radius, this single-end tool produces smooth, radiused transitions that reduce stress concentrations and extend workpiece life. The 3-flute helical geometry and TiB2 (Ti-NAMITE-B) coating improve chip evacuation and surface finish at elevated cutting speeds. At 3 inches overall length with a 1/2 inch length of cut, this short-series end mill is suited for rigid setups where deflection control matters. Machinists and toolroom operators in production and job-shop environments rely on this geometry for finishing and light roughing passes on aluminum, copper, brass, and similar non-ferrous materials.

The SGS 35678 is built for use in vertical and horizontal machining centers as well as manual mills equipped with end mill holders. Its straight-cylindrical shank at 3/8 inch diameter fits standard ER and end mill holder collets. The coarse-pitch, right-hand helical flutes with right-hand cutting direction are optimized for non-ferrous metals coded N under standard material classification. The Series 43CR designation places this tool within SGS's corner radius end mill family. Typical applications include profiling, slotting, and peripheral milling in aluminum alloy components, prototype work, and fixture fabrication.

Key Features

• TiB2 (Ti-NAMITE-B) coating reduces built-up edge and improves tool life in non-ferrous materials
• 0.06 inch corner radius minimizes chipping at the cutting edge and reduces workpiece stress risers
• 3-flute helical geometry balances chip load and surface finish for non-ferrous machining
• Short-series length (3 inches OAL, 1/2 inch LOC) promotes rigidity and reduces deflection
• Right-hand cut, right-hand flute direction with coarse pitch for efficient chip evacuation
• Straight-cylindrical shank compatible with standard end mill holders and ER collet systems

Compatibility

Designed for use with end mill holders in CNC machining centers and manual mills. Optimized for non-ferrous metals including aluminum, brass, and copper alloys. Primary workpiece material code N per standard material classification.

Installation Notes

This tool is installed by machinists using standard end mill holders or ER collet chucks - ensure the holder bore matches the 3/8 inch shank diameter and that runout is minimized before engaging the cut. Always power down the spindle and confirm it has come to a complete stop before changing tooling. Confirm tool projection and stick-out match the intended depth of cut to maintain rigidity. Follow your machine tool manufacturer guidelines and applicable shop safety procedures when setting tool offsets and feeds.
