Disc groove cutters are perfect when narrow, clean grooves are required – for example, for back panel grooves, drawer bottom guides, or tongue-and-groove joints. Thanks to their compact design with a large diameter and narrow cutting width, they operate smoothly, precisely, and save material. Many models can be adjusted in groove width using spacer rings. Suitable for handheld routers, router tables, or CNC machines – they are particularly popular in furniture construction, interior design, and precision work.
