When you need a reliable corner radius end mill for CNC finishing, the SGS S04607 set from Kyocera SGS is worth a close look at USD 229.00. In the tooling cutters abrasives market, this carbide set brings a specific geometry, so the real question is whether it matches your part depths and materials.
What You Get
5 pcs) New SGS 12mm (0.4724") 1.0R Corner Radius 6FL Carbide End Mill S04607
The set contains new solid carbide tools with a 12mm cutting diameter, a 1.0mm corner radius, and six flutes. The visible spec line on each tool lists a 26° helix, right-hand cut, 15mm flute length, 74.5mm overall length, and a 1/2-inch shank. The TA coating is included, which is part of the design for heat resistance and wear. That six-flute, coated configuration is a strong reason to choose it for finishing work, while the 15mm flute length sets a clear boundary on depth.
Who It Suits
This set is a natural fit for CNC shops that already run 12mm tooling and want a consistent supply of the same edge geometry. The TA coating and six flutes are useful in harder materials where surface finish and edge life matter. The right-hand cut matches standard milling spindles, and the 1/2-inch shank fits a wide range of collet holders and shrink-fit chucks. If you do multiple setups or batch work, having five identical tools means fewer tool-offset changes.
Trade-offs
The 15mm flute length is the main constraint. You can profile and finish shallow features, but deep cavities or long wall cuts will require a different tool with more flute length. The 74.5mm overall length is compact, so check your spindle clearance and holder design if you extend far from the spindle. Chip evacuation can become a concern in softer, gummy materials; you may need to reduce feed rates or adjust coolant pressure to keep the flutes clear.
Bottom Line
At USD 229.00 for five tools, this set is an efficient way to keep a consistent edge geometry on hand without ordering single end mills one by one. The solid carbide construction supports dependable performance for the right job. If your parts stay within the flute depth and you need a finishing tool with the right corner radius, the SGS S04607 is a straightforward pick.
