CARBIDE SERIES ANNULAR CUTTERS
HEAVY DUTY TCT CORE DRILLS
Carbide annular cutters are heavy-duty core drills for metal equipped with precision-brazed tungsten carbide tips (TCT). Designed for drilling hard and abrasive materials, they deliver high cutting stability, exceptional wear resistance, and extremely long tool life. Ideal for structural steel, stainless steel, cast iron, and demanding industrial drilling applications.
Engineered in Germany, TCT annular cutters for metal drilling ensure fast penetration, clean holes, and reduced vibration even in tough materials. The carbide cutting edges enable higher cutting speeds and improved productivity. Perfect for large diameter drilling with magnetic drilling machines in steel construction, fabrication workshops, and heavy-duty industrial environments.
