The drilling of bone is ubiquitous in many fields of surgery including opthopaedics, neurosurgery, craniomaxillofacial and ear nose and throat (ENT). A cylindrical tunnel is typically prepared in bone using a surgical drill-bit to accommodate a screw or other threaded device for rigid fixation which is provided by the integration of bone (cancellous and/or cortical) with the screw threads. In this configuration bone screws are resistant to axial and shear forces as well as bending moments and therefore suited to the load-bearing function of the skeleton during locomotion.

Standard tipped drills can slip or skid when making the initial entry into the bone especially when the angle differs from 90 degrees. Anti skid drills have a very sharp point on the end which bites into the bone and holds the drill in place, ensuring the hole is exactly where you need it.

For drilling over A-wires when drill hole angle and site are critical.

Comprises four stoppers in an autoclaveable case simply choose the nearest stopper to your drill bit and lock it off at the required drill depth.

Our popular Evodurance® range has been improved, they still cut quickly and precisely as before but they have been strengthened to ensure even the most heavy-handed surgeon can use them. Drills are coated in TiN (Titanium Nitride)
-
We have added the most common sizes and lengths to our standard drill range and offer a set price for all sizes. These drills offer excellent value. The bottom drill bit is coated in titanium Nitride which makes it even more hard wearing.
