Variable taper vs constant taper We all use a constant tapered file system called the HAND FILE sequence 10/02 then 15 /02 constant tapered files are constrained by the fact they have to be the same taper up the entire file. This basically means that there are big jumps in width between successive files. 10 02 to 15 02 (k files is 50% wider at the tip) Constant tapered rotary files suffer from the same issue! Variable taper overcomes this by creation of a file that is small at the tip for exampl
