Sigerio 4-in-1 Router Milling Groove Bracket

The Sigerio 4-in-1 Router Milling Groove Bracket is a multifunctional woodworking jig crafted from thickened aluminum alloy. It combines circle cutting, edge milling, round groove cutting and a standalone router base into a single adjustable toolkit. The modular three-section design allows quick reconfiguration for diverse joinery tasks. Both centimetre and inch scales are marked on the body for direct measurement.

Woodworkers needing one adjustable jig for circles.

This jig suits hobbyists and professionals who want a single fixture for layout, circle routing, edge trimming and round grooves on various board materials. It requires a trim router with at least two diagonal mounting holes that match the base pattern. Builders using large production routers or machines without the specified hole pattern cannot mount this bracket and should look at other solutions.

Aluminium alloy construction

The body is made from upgraded, thickened aluminium alloy that resists flex during routing operations. An adjustable radius mechanism lets the user set the exact cutting distance for circles or grooves, while the printed metric and imperial scales remove the need for a separate rule. The detachable slotting support locks onto the base to guide the router along straight or curved paths with consistent depth.

  • Dual inch and centimetre scales for flexible measuring
  • Modular aluminium base mounts directly to trimming machines
  • Adjustable radius and distance suit varied groove cuts
  • Three detachable sections reconfigure for different routing tasks

Questions about this item

How do I mount the aluminium alloy base to my trim router, and which holes must line up?

Only the two diagonal holes on your router’s base plate need to match the bracket; fasten those first, then add the slotting support if you are cutting round grooves or edge milling.

What parts will wear or need replacement after extended use?

The adjustable radius mechanism and the detachable joints are the moving components most likely to loosen or wear; keep the locking screws tight and lubricate the sliding surfaces periodically.

At what point does the tool hit its limit during a long routing session?

The bracket is not rated for large router tools, so sustained heavy cuts with a high-powered motor will cause deflection or overheating before the aluminium itself fails.
