The cutting angle of the edges is designed to give the practitioner constant suction-free control of the progress of the drill in the bone. The open point angle of the final drills reduces apical over-drilling and therefore reduces the invasiveness of the osteotomy.
The 3 lips give the drill excellent stability at the start of drilling. The standard incrementation of the diameters from 0.5 mm to 0.7 mm provides adjustable progressive preparation according to the bone type.
With this design, the drilling axis can easily be corrected when necessary. The helical grooves and the escape angle of the drills promote optimum removal of shavings, regardless of bone density.
Finally, Global D drills are machined by the leading companies specialising in the manufacture of cutting tools for medical applications.
