Herdim System Smoothing Reamer with 1/4 Hexagonal Shaft, Taper 1/30
Herdim Reamer for Violin, Viola Peg Hole bushings, Spiral Edges, TIN-coated. 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.

Herdim Reamers Made in Germany
Precision tools for shaping the peg, endbutton and endpin holes of stringed instruments. The reamer blades are made of High Speed Steel (HSS)
hardened to 62 HRC to guarantee exceptionally long-lasting edges.
Straight cutting edges
The triple straight cutting edges are particularly sharp and guarantee perfectly round holes. Boxwood handles.
Spiral cutting edges
The spiral design allows the wood fibers to be cut at an angle, resulting in completely chatter-free performance and perfectly round holes. Especially well-suited for working on sensitive old instruments whose pegboxes often have very hard medullary rays. Rosewood handles.
The titanium-nitride coating (TIN) triples the reamers edge life, protects it from corrosion and reduces friction during use. By allowing a smoother and gentler cut, it also reduces the stress placed on the pegbox. The TIN coating does not affect the sharpness of the reamer.
