    • A dental bone cutting tool (15) for machining recesses for anchoring a dental implant is disclosed. The implant comprises a pair of blades juxtaposed and coupled in parallel with each other and a head for supporting a denture. The head is supported by the two blades and has a base surface continuous with the blades. The tool (15) comprises a pair of large diameter cutter disks (16) constituting each a circular saw blade with a peripheral cutter edge and securely mounted on a hollow rotary shaft (18) for cutting the two parallel grooves for accepting the two parallel blades, respectively. Smaller diameter cutter disks (17) are also clamped in parallel together and mounted on the rotary shaft, and so numbered and sized as to collectively constitute a unitary rotary cutter for cutting a recess so sized and configured as to accept at least a portion of the base surface of the implant head in the jawbone. A coolant is supplied through the hollow rotary shaft and via the cutter disks into the cutting zone.
