Working and functionality of disc groove cutters

How do you work with a disc grooving or lamello cutter?

When milling with a disk grooving cutter, the straight or curved workpiece is guided along the ball bearing – because thanks to the ball bearing you can place the wood directly on the wood and mill it without lateral guidance.

groove depth:

The diameter of the ball bearing determines the groove depth and thus the size of the biscuit. If you buy a RUWI disk grooving cutter, you have a cutter with a 49 mm long shank and 8 mm diameter at your disposal. The tool has two carbide cutting edges (HM) with a width of 4 mm. This groove width is matched to common biscuit dowels (or form springs, Lamellos, etc.). In order to get the right groove depth, the nut can be loosened at the top and the ball bearing replaced.

Tip: The set contains three ball bearings with a diameter of 15, 19 and 23 mm. These are matched to the milling cutter diameter – depending on the ball bearing, you get the right groove depth for form springs in sizes 0, 10 and 20.
