Milling Groove Holder (Fräsrillenhalterung) — precision guide for circular cuts compatible with trim routers Key benefits Accurate guidance for circular cuts: provides a stable reference that produces clean, repeatable circular cuts and reduces wobble or drift. Easier, safer routing: lightweight and simple to position, so you can work confidently and finish faster with fewer adjustments. Broad material compatibility: designed for solid wood boards and medium-density fiberboard (MDF), expanding the range of projects you can tackle without changing tools. Trim‑router compatibility: specifically made for use with trim routers (trimming machines), helping you achieve professional-looking results with commonly used handheld machines. What makes it stand out Lightweight aluminum alloy construction: combines easy handling with the strength and stability needed during routing operations. Purpose-built for circular routing: optimized to guide the cutter reliably for concentric, smooth cuts rather than ad‑hoc or improvised guides. Durable and user-friendly: corrosion-resistant aluminum keeps the guide rigid over time while remaining easy to mount and adjust. Typical applications Cutting precise round openings for speakers or ventilation in cabinetry and panels. Making clean circular cutouts for cable or pipe access in furniture and built-in fixtures. Producing decorative round insets or tabletop openings in solid wood and MDF workpieces. What to expect in use Consistent, clean edges on circular cuts when paired with a compatible trim router. Reduced need for corrective sanding or rework thanks to the accurate guidance. A lightweight, robust guide that maintains stability for repeatable results across multiple workpieces.
