Abstract: The invention relates to a resin bonded cut-off tool. The resin bonded cut-off tool comprises rod shaped sintered bauxite abrasives, wherein an amount of the rod shaped sintered bauxite abrasives is at least 10% to 90% by weight, based on 100% by weight of a Grinding Active Matrix (GAM) of the cut-off tool. The resin bonded cut-off tool comprises further a bonding agent in an amount of 10% to 40% by weight, based on 100% by weight of the GAM of the cut-off tool and fused and/or sintered abrasives in an amount sufficient to bring the GAM of the cut-off tool to 100% by weight.
