Kartiokalvain 16/8 mm 1/25, spiraali

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. 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 more gentle cut, it also reduces the stress placed on the pegbox. The TIN coating does not affect the sharpness of the reamer.
