Spiral groove cutter
Spiral groove cutters are suitable for processing all types of wood, such as softwood, hardwood, as well as all wood and board materials. Also Plastic can be routed with the router at an appropriately regulated speed. They are also ideal for the use in CNC routing. Furthermore, these routing cutters are also excellent for immersion, i.e. also for recesses and drilling.
Advantages of spiral routing cutters
- the cut is uniform and therefore clean
- reduces vibrations
- pulling speed is increased during routing

Difference between right- and left-hand twist
Depending on the application and machine, please note whether you require a spiral grooving cutter with right-hand twist or left-hand twist.
A right-hand twist, also called an "up-cut", is recommended for fast work. Here the chips are ejected immediately and clogging is avoided. The result is also a very clean groove bottom.
Spiral groove cutters with left-hand twist, "Down-Cut", on the other hand, work with a pulling cut and produce an enormously clean cutting edge and are therefore ideally suited for use where the Edges remain visible afterwards. Disadvantages are the chip removal downwards, a not so clean groove bottom and the slower feed speed.
Right- and left-hand helical pitch (compression) / ‘Up- and down-cut’: this geometry of the spiral groove milling cutter, also known as a finishing cutter, combines both helical directions and enables both a pulling cut (clean groove edge) and a groove bottom.
