Finishing shell reamer for metal fi 53

Professional finishing shell reamer 53 H7 machine NRNb, section 53 mm, in accordance with DIN 219, designed for finishing cylindrical holes. It is a push-on finish reamer with a tapered shank, with straight chip grooves. Slip-on 53 machine reamers of this type are suitable for improving the roughness of the hole surface, leading out the hole axis, increasing the diameter of the hole, and also for obtaining perfect dimensional conformity. Reamers from our offer are produced from special HSS high-speed steel, thanks to which they allow machining of very hard and hard-to-machine materials of P1.2 - P1.3. class These are carbon steels, metal alloys, metals, thermally hardened plastics. They can be used for various types of conventional and numerical computer-controlled machine tools - CNC. Reamers are distinguished by higher resistance to mechanical damage and longer service life.
