Important details to remember with reamers

The purpose of standard reamers is to produce holes inside moulds. Moreover, they smooth and debur any imperfections or edges on an object. With a mould reamer from Penico, you can take care of various mould repair needs. As a result you can remove any faults you encounter in a comprehensive manner.

In order to meet the needs of their clients, shops must employ the right finish tools. Reamers fall into this category. You can't just jump straight in with them however. There are certain things you have to remember about these tools.

Stock allowance

To begin with, one of the crucial elements of reaming is stock allowance. When there is too much, it can lead to chattering when the reamer enters a hole. This additional stock heightens the tool pressure considerably. It is possible that your reamer may not chatter from this stock. However, the reamer's cutting area is rather compact. The added material that passes over your cutting zone shall deteriorate it rapidly. It will lower the tool life as well.

In contrast, when there isn't enough stock, the reamer pushes instead of cutting. Additionally, there might not be enough stock to completely clean the hole up from the drill procedure.


You will need to think about runout too since it can cause problems during the reaming process. It is also the same for various other machining procedures. High accuracy toolholders are important so you can fight runout. Shrink fit and hydraulic holders are good examples. When working with microns or tenths, the procedure has to be secure.
