Herdim Spiral Cello Endpin Reamer, Tin Coated

Herdim Reamers
Made in Germany
Precision tools for shaping the 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. 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. Hardwood 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.
