TCT annular cutters, also known as tungsten carbide tipped core drills, are premium hollow cutting tools designed for magnetic drill machines. Brazed robust tungsten carbide tips onto high-alloy steel bodies, they deliver outstanding hardness, wear resistance and heat resistance, outperforming standard HSS annular cutters on hard metals. The multi-tooth flute design optimizes chip evacuation, reduces friction and avoids overheating during continuous drilling.

Compared with traditional twist drills, TCT annular cutters only cut the outer ring of the hole, leaving a solid slug. This design saves power, speeds up drilling, and produces clean, burr-free precise holes with minimal secondary finishing. Longer service life lowers your tool replacement cost.
They work excellently on mild steel, stainless steel, cast iron, aluminum and high-strength steel. Widely used in steel structure fabrication, bridge engineering, shipbuilding, railway, power projects and heavy machinery maintenance. Suitable for workshop production and on-site field drilling.
