GRK's R4 self-countersinking screw has six self contained cutting pockets which act like a router and transport the drill dust away from the edge of the screw hole. In addition, the R4's patented head design also features cutting teeth which enable the R4 to flawlessly and effortlessly work in any material without the need for countersinking. In fact, the R4 head design is so effective that it will not crack even the most brittle of materials, such as melamine... and all this without pre-drilling or pre-countersinking.
