Abstract of the Disclosure A cementing/plug drilling apparatus consists of a flat plate slightly less in maximum diameter than the pipe in which it will pass having at least one protrusion or tooth on both faces, the tooth being strong enough and sharp enough to engage, dent and penetrate a cement surface and a pump down wipe plug and, the plate having an opening on each face in fluid communication with each other through a fluid passage. An improved process of ce- menting and drilling through a pump down wipe plug comprises placing a plate having teeth on both faces between a pump down wipe plug and the surface that the bottom of the plug contacts during the cementing process, so that when the drill bit contacts the plug the teeth on the top of the plate engage and hold the plug and the teeth on the bottom of the plate engage and hold the surface on which they are in contact, thereby retarding the tendency of the plug to slide over the surface below it and enhancing the drill- ing action of the drill bit.
