These pages contain technical information relating to the selection and use of cutters and collets in your CNC router.

You also can download a useful Cutter Guide wallchart which contains suggested tooling and their feeds and speeds for cutting various materials.

The importance of the part played by cutters and their holding mechanism in a CNC router is often overlooked with the result being reduced productivity and poor quality of parts produced on the router.

Actually, the cutter is one of the most important components and is the one which can has the most impact on the performance of the machine in terms of cut quality and productivity.

Of course, the machine settings, including feed rate, depth of cut and spindle rpm, also can have a major effect on the machine performance. It is important to understand that if the wrong cutter is being used, no amount of tweaking of the machine settings ever will achieve optimum performance.
