Gates Drill


Pack of six Gates Glidden drill size  #4 ; 32mm

I have only one size to clean the access of the canals.  If the canal has a broader opening than the drill, while on I “wipe” the drill gently around the circumference to clean the edges.  Remember the size of no. 4 drill is equivalent to a size 110 file!  I only use them to widen the orifice for straight line access.  Note the non-cutting tip and eliptical shape of the drill.  They are very aggressive drills.  I do not advocate using smaller drills as the clinician will tend to use them more apically and risk strip perforations.
