Euroboor TCT (SANDVIK) annular cutters are equipped with a spiral flute which ensures optimum chip removal and makes seizure virtually impossible. These annular cutters are used for hardened materials such as HARDOX steel, stainless steels, and high tensile strength steels like railway tracks. Thanks to their composition, and when used correctly, these cutters are less prone to breakage than standard High Speed Steel cutters, especially in larger diameters and lengths.
Extremely hard and durable tungsten carbide cutting teeth (SANDVIK) for the toughest drilling tasks. Offset positioning ensures the lowest possible heat development.
Cutters with a diameter up to 60 mm (2 3/8") (with Depths of Cut of 35, 55, 75, 100, 150, and 200 mm): – These use a 19.05 mm (3/4") Welnit shank.
Cutters with a diameter of 61 mm (2 7/16") and above (regardless of Depth of Cut): – These use a 31.75 mm (1 1/4") Weldon shank.
In short: – Smaller diameters (up to 60 mm / 2 3/8") = 19.05 mm (3/4") Welnit shank. – Larger diameters (61 mm / 2 7/16" and up) = 31.75 mm (1 1/4") Weldon shank.
