The ultimate in versatility the universal countersink changes diameter to whichever drill bit it is attached. Simply unscrew the two hex head securing bolts and place over the drill bit you want and it instantly adjusts to accommodate the size of drill. The tungsten carbide cutting edges cut cleanly. Suitable for use with 3.0mm to 7.2mm drill bits, the universal countersink can also recess the hole if required by plunging the bit further into the material. Drill bits not supplied.

Good in theory...A simple an well-designed device but on trying it out for the first time in a piece of veneered mdf the carbide tips crumbled. I decided to return it and somehow it managed to fall out of the packet as I went home. I now have a £25 allen key.

Multipurpose universal TCT countersinkVary well made TCT countersink and usuable above the stated 7.2 mm. Can be used for extremely accurate counter-boring 8mm (and larger) holes by mounting a stub of silver sttel with longer cap-head screws and making two locating grooves for the screws on either side of the stub. Can be used to countersink from either side of the work piece using a reversible cordless drill. Excellent piece of kit.
