Spiral groove cutter for tear-free cuts
Where are spiral grooving cutters used?
Spiral groove cutters are suitable for processing all types of wood, such as softwood, European or tropical hardwood, as well as all wood and board materials. Also Plastic can be milled without problems 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. Please refer to the imprint on the cutter shank for recommended turning speeds.
Advantages of spiral routing cutters
- Thanks to the spiral cutting edge, the cut is uniform and therefore clean.
- The more even flow reduces vibrations.
- The pulling speed is increased during routing.
Conclusion: faster, cleaner cut!
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/right-hand rotation or left-hand twist/left-hand rotation.
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.
