Peg Hole Reamer, Violin, Herdim, 1/20 taper TIN Coating

Herdim Reamers are Made in Germany. 1/20 Taper (Irregular) 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. TIN-Coating - The titanium-nitride coating (TIN) triples the reamer’s 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.
