Ring-free machining™

Machining cast iron spool bores

A common problem when machining spool bores is that rings are produced in the bore by the rough pass reamer.

 

The following manual removal of these rings prior to finishing/assembly is a time-consuming and costly process.

 

A patented process and tool technology eliminates the rings, and gives you considerable savings.

 

Chips are pushed out automatically while drilling and no rings are produced by the rough pass reamer!
