A method of redistributing the binder phase of a cemented carbide mining insert having a WC hard-phase component, optionally one or more further hard-phase components and a binder includes the steps of providing a green cemented carbide mining insert; applying at least one binder puller selected from a metal oxide or a metal carbonate to only at least one local area of the surface of the green cemented carbide insert; sintering the green carbide mining insert to form a sintered cemented carbide insert; and subjecting the sintered cemented carbide insert to dry tumbling process executed at an elevated temperature of or above 100 C., preferably at a temperature of or above 200 C., more preferably at a temperature of between 200 C. and 450 C.
