The reamers are used sequentially beginning with a 2.5mm diameter and ending with the diameter of the intended implant. The latch reamers have horizontal markings at 6.0, 8.0, 11.0 and 14.0mm, whereas older reamers did not have the 6.0mm mark. It is imperative that the depth indicators on the latch reamers are identified prior to surgery. No assumptions should be made about the height of the first marking on any latch reamer.
