Herdim System Smoothing Reamer with 1/4 Hexagonal Shaft

The cutting edges of the regular Herdim reamers are bevel ground to a sharp edge, resulting in an aggressive cutting action. This smoothing reamer however has cutt­ing edges which are on one side slightly rounded, according to the radius of the reamer. This reduces the cutting performance but improves the surface quality and roundness of the hole. We recommend using this reamer as a finishing tool in addition to the regular reamers, for highest demands in the peg fitting process. The drills can also be driven with a cordless power drill. In this case the cutting action is especially smooth and effortless.Spiral cutting edges with TIN coating.
