Type “B” only the countersink is diamond electroplated, a standard masonry bit is used as the drill. Can be supplied between 5.5 - 9mm

Type “C” electroplated diamond countersink is complemented by a plain pilot to centralise countersinking with the original hole.

Type “D” electroplated diamond plain countersink is manufactured to a point.
