A Countersink is a kind of conical shaped hole, which is cut into a manufactured object, or the cutter used to cut such a hole. It is commonly used to allow the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material. Our range of counter sinks is between 4mm to 35mm diameter which is manufactured as per DIN-335 Form C and Form B.
