100mm Cut Depth TCT Annular Cutter 18mm-250mm Cut Dia Core Drills | H11 Body K30 Carbide Tips

Introduction of TCT Annular Cutter

Our 100mm cutting depth TCT annular cutters feature H11 tool steel body + K30 grade tungsten carbide tips. H11 substrate provides high toughness, anti-deformation performance under heavy cutting load. K30 carbide cutting tips deliver outstanding wear resistance for continuous thick plate machining.

Designed for magnetic drill machines, this cutter maintains stable cutting performance on thick high-strength steel. Compared with HSS annular cutters, TCT tips have excellent red hardness, less thermal wear and longer service life, especially for continuous heavy-duty drilling. Multiple shank types available (Weldon, Fein, universal shank). We also support non-standard custom sizes and OEM private label for European & US clients. Flexible MOQ, fast lead time and reliable after-sales support.
