FAQ
Do the selectable sizes indicate the inner or outer diameter? The selectable sizes indicate the outer diameter. Each option has an inner diameter that is 1.0 mm smaller, as shown in the size guide.
Can this drill be used for bone ring and bone cylinder preparation? The trephine cuts around the outer circumference of the bone section. It can be used during bone ring or cylindrical bone graft preparation, with additional preparation steps determined by the procedure.
Does the side window provide internal irrigation? The side window is an opening in the working head. It should not be interpreted as a confirmed internal irrigation system.
