Adjustable hand reamer 74-84

Manual adjustable reamer74-84 hand reamer, arbor. The reamer is a tool used for the final machining of a cylindrical hole at the required higher accuracy class. It is used to achieve high dimensional accuracy and surface roughness.

Professional 74-84 NRZe adjustable re amer, designed for manual reaming of holes. It is an arbor reamer used for final machining of cylindrical hole when higher accuracy class is required. It is designed for machining previously drilled holes with a drill or reamer peeler. It is used to achieve very high dimensional accuracy of the hole, lower surface roughness, eliminate machining allowances, as well as improve the hole axis. The ability to adjust the blades in ranges from 7.2 to 8 mm allows you to freely adapt the machining to the current design requirements. The 74-80 adjustable reamers offered in our store have a 45-degree bevel. This allows to reduce the contact of the surface of the reamer with the surface of the hole, as well as easier introduction of the tool into the hole. Reamers of this type allow the processing of holes "at the ready" - after previously drilling the hole with a drill or after using a reamer peeler.
