RaCe is an acronym standing for Reamer with Alternating Cutting Edges. The cross-section of the RaCe instruments is a convex triangle, with the exeption of the two smallest instruments, #15/02 and #20/02 (taper 02), which both have a square cross-section. In the manufacturing process, special attention has been focused on achieving a smooth metal (NiTi) surface of the instruments. Each RaCe instruments has a constant taper throughout the working area, ranging from 02 taper to 10 taper, depending on the instrument. The instruments have a rounded tip (see photo folder) and three sharp cutting edges. The instruments are made of nickel titanium, however, two Pre-RaCe instruments are available also as steel instruments (Pre-RaCe #40/10 and #35/08).
