A unique screw driver tip for screws having recessed sockest of the Robinson type are specifically disclosed. The driver tip has a recessed face which defines between the face and the side walls of the tip cutting margins which act as a scraping devices as the tip is in inserted into the socket to thereby scrape the side walls of the socket clean. This allows proper mating penetration of the tip into the socket and hence mating of the tip with the socket whereby the driver may then be turned and the screw rotated so that the screw may be easily removed. The profile features of the tip allow cleaning of the socket and fip penetration into the socket by one single and continuous motion.
