I tried processing rubber with a standard T-slot cutter (TC・ST-TC).

三洋工具 長野事業所、東京本社、名古屋営業所、大阪営業所、マレーシア工場、メキシコ工場
Tool used: TC-D20・ST-TC-D20 (staggered blade) Groove width: 3mm Depth: 3mm (one-pass processing with upper cut) Can also be used on materials other than metal. If processed at high speed with low feed, both TC and ST-TC will finish beautifully.
