Reamers(Groove Shape:Helical)

An online store for reamers. In MISUMI's e-catalog (online general catalog), specifications/dimensions of tool diameter (blade diameter), groove length, work materials, delivery date, etc. can be selected with one click, so you can easily find the desired cutting drill. In addition, re-polishing according to the desired shape can also be done. Contact us if drills from the tool manufacturer you are looking for are not available.

[What is a reamer?]
A tool to enlarge the hole made by drills, etc., and to adjust the shape. There are several blades on the cylindrical or conical body, and it scrapes the inner surface of the hole by manual rotation and force for shape. Depending on the application, there are products for roughing, for finishing, etc. and the shape of the blade is straight or spiral. The conical shape conforms to a wide range of machining hole sizes, while the hole also has a conical shape. On the other hand, the holes of cylindrical items are also cylindrical, and as the size is fixed as it is, there are also systems in which the thickness is variable.
