* Countersink drill bits form pilot holes for screws and create a conical recess for the screw head.
A countersink drill bit is best used on soft materials such as wood or plastic, and will not work on
metals. It is often preferable to create the countersink first, then drill into the center. Counter sink
drill bits can be used with power drills and some routers. Using a combination counter sink and
clearance drill can create both the counter sink and the pilot hole in one action. An adjustable stop
can be used to fix the depth.
* Naturally different sized countersink drill bits create different sized countersinks and holes. Some
counter sinks are available with fitted handles so that the shallow depression for the screw head
can be formed by hand, eliminating the need to constantly change bits. Some countersink drills can
remove plugs of wood before creating the hole. These plugs can then be used cover the recessed
screw heads.
