Drill Countersink These drill bits produce a clearance hole for a wood screw, countersink the hole and finally produce a counterbored hole. Plugs to fit the counterbored hole may be produced with our parallel plug makers. These drills are suitable for use in routing machines or drill presses. All cutting edges are TC tipped, ensuring a long service life whether cutting solid timber or man made boards. More Info...
