Because they have a completely innovative geometry the drills ANNULAR ITAL Drills (also called "copo", Annular drills or drills "cutter") performing holes with great economy of mechanical energy, in relation to a twist drill. Because "cut" just a ring of the hole to be executed, that is, only part of the total run of the hole is transformed into chips, a large amount of energy is saved by using these drills copo.

The larger the diameter of the hole that is being run by a annular drills, the greater the volume of material "not sheared" and therefore greater energy savings.

Example: For a hole 1 "made with a drill annular, when comparing execution of the same hole made with a common helical drill, the energy savings is about 25%! Whereas for a 4" hole economy is 75%!
