Turning Inserts（Shape：R (Circular)）

An online store for inserts (for turning). In MISUMI's e-catalog, specifications/dimensions of brand, shape, application, compatible work materials, etc. can be selected with one click, so you can easily find the desired product.
[What is turning?]
A shape is created by rotating the work material and cutting the surface while pressing the cutting edge. Processing methods can be divided into outer diameter processing, threading, inner diameter processing, and cut-off processing. The model numbers written on the insert and holder are codes unique to each tool manufacturer. Understanding how to read the model number provides basic information such as shape, type, and size. In many cases, cutting conditions are written on the label of the insert case, so check it before use.
