The Rotabroach™ Raptor Cutters have a unique and exclusive geometry. They are designed to ensure that they will last longer, cut faster and give a better and more accurate finished hole than any other annular cutter. The cutters are manufactured from high-speed steel (HSS) with the addition of aluminium (M2AL) and heat-treated to a high temperature to ensure excellent hardness.Select Option Kit: 14,16,18, 20, 22mm & 2 PinsKit: 14,18, 22mm & 2 Pins Add to Basket Quantity
