This Slim line Vacuum attachment allows the practitioner to add the benefit of having a vacuum to their hand piece. From trial of different size tubes we found that this was the most comfortable and low profile while still allowing the vacuums to function without blocking for the longest time. The tube is seamless stainless steel (a seem would cause a rough area that dust would cling to and cause clogging more frequently) The unit fits snug to a hand piece through a mounting with two screws. The mounting should be fitted up agents the handle part of the hand piece therefore not getting in the practitioners line of view to the burr. All in all the piece proved very efficient and added little to no adjustments to the user having the extra attachment.
