Finishing shell reamer for metal fi 25

High-grade finishing shell reamer 25 H7 NRNb, complying with the dimensional standard DIN 219. It is designed for finishing cylindrical holes, through-holes and blind holes - ready. It is a slip-on finishing reamer with a tapered shank. It is used to achieve perfect dimensional accuracy of the hole, correct previous errors, remove unevenness, improve roughness of the hole surface. It can be used on both conventional machine tools and modern computer-controlled numerical control machine tools. In our store we offer you professional slip-on 25 machine reamers produced from modern high-alloy HSS. The content of this element significantly strengthens the technical parameters of the tool. First of all, reamers are very resistant to heavy cutting conditions and very resistant to any mechanical damage. They can be used for machining alloy steels, cast steel, cast iron and other very hard materials.
