Frequently asked questions
What is an adjustable grooving cutter and on which machine is it used?
The Bernardo Ø 160 mm adjustable grooving cutter is a tool for spindle moulders (standard Ø 30 mm spindle) designed for making calibrated grooves in solid wood and panels. Unlike single shank cutters, this tool has an adjustable groove width from 12–24 mm — allowing you to adapt the groove width without changing tools, reducing setup times. Used to create tongue and groove joints, panel seats, dados, and fastening profiles.
How is the groove width adjusted?
Adjustment is made via the lateral expansion system: the two halves of the tool move, bringing the lateral cutting blades closer or further apart. The adjustment is graduated — check the millimeter scale engraved on the tool. For precision grooves, always perform a test pass on scrap material and measure the actual width before proceeding with the final piece.
What materials does it work on?
Solid wood (hard and soft), chipboard panels, MDF, plywood. Not suitable for metals — the inserts are optimized for wood. On MDF and melamine-coated panels, reduce the feed rate to avoid fraying the edge of the groove.
What spindle speed should be used?
For Ø 160 mm grooving cutters: 3,000–6,000 rpm on solid wood. On MDF: 4,000–8,000 rpm with reduced feed rate. The optimal peripheral speed is 40–60 m/s — do not exceed the maximum speed indicated on the tool.
Are spare parts (blades/inserts) available?
Original spare parts available with 3–5 working days shipping. Customer support in Italian available.
