Like Big Mac to McDonald's; the R8 collet is to Bridgeport. Bridgeport
set the standard for milling machines and was one of the industry leaders when it came to equipment for CNC milling. Their invention of the R8 collet represented a true revolution in milling. It also caused the need for R8 tool holders to hold those R8 collets.
R8 Tools Allowed Rapid Tool Changing
R8 collets made for a giant leap forward in machining. They allowed rapid tool changing and actually paved the way for automated tool changing. Little did they know!
With R8 collets, the collet fits into the taper itself. This requires an exact match between the collet and the tool shank. In the R8 design, the collet is compressed by a drawbar from behind. R8 collets have no separate chuck. They are self-releasing. These two characteristics led to the transformation of tool changing and gave birth to automated tool changes.
Also, because the tool is firmly in the taper, you get more rigidity from the end mill. This results in more efficient work on a reliable basis and that is better. More than better, it is the R8 tool advantage.
R8 Tools for Quick Change
Faster than the transformation of Clark Kent into Superman, R8 collets are the quick change artists of the CNC shop. Just as important as the machine and the software running it, the R8 collets facilitate rapid tool-changing. Rapid tool changing is another way to increase productivity in the shop. Just do any simple Google search of the term R8 collets and you'll find pages with headlines like
The search will also show you that R8 collets aren't cheap. As any CNC'er knows the tooling can be as expensive as the mill itself. Tooling is an investment that you must protect. But those R8 collets are at risk every time they are transported to and from storage. If they aren't stored in a tool crib, they are at risk during storage as well. That's where special R8 tool holders
come in handy.
