UJK Circle Cutting Jig (with 8mm Shank Spiral Router Cutter) - Circles from 40mm to 1251mm.

The high-precision UJK Circle Cutting Jig is an advanced woodworking template designed to allow perfect routing of circles, discs, and arcs using a plunge router. This innovative solution from the British brand UJK offers complete independence and mobility when working in the workshop or directly on-site at a client's location. Thanks to its carefully thought-out design and high-quality manufacture, this tool guarantees excellent accuracy and repeatability for every single cut.

Applications:

• Precise cutting of circles and discs from 40 mm up to 1251 mm in diameter with adjustment accuracy down to 1 mm.

• Creating circular recesses, decorative circular routing, and openings for installation elements such as sinks, speakers, or decorative features.

• Working with a wide range of materials, including softwood and hardwood, MDF, plywood, chipboard, and plastic sheets.

• Sizing large radius arcs and curves using the stable extension arm supplied in the set.

Key Advantages:

• Unrivalled setup precision – the unique spiral calibration scale allows smooth and extremely accurate adjustment in 1 mm increments, completely eliminating the need for time-consuming measuring and test cuts.

• Perfectly vertical pilot hole – the included precision drill guide and 3 mm drill bit ensure that the hole for the pivot pin is drilled perfectly perpendicular, which is critical for achieving flawless circle geometry.

• Smooth and stable rotational movement – the use of closely matching pivot pins (short and long) seated in 3 mm holes prevents any lateral play, resulting in immaculately smooth edges after machining.

• Versatility and compatibility – the jig's base plate is double-sided. It features clear markings on both sides (dedicated to 6 mm and 12 mm cutter diameters), allowing easy adjustment of the tool to the thickness of the workpiece material.

• Clean and effortless cutting – the included solid carbide UJK Upcut spiral router cutter (6x22 mm) with an 8mm shank clears chips upward perfectly, preventing edge burning and guaranteeing an excellent finish.

• Modular high-reach design – the stable metal extension arm allows for quick expansion of the working range without losing structural rigidity or affecting routing precision.

• Robust materials - the base plate and the rule are made of 8 mm thick aluminium.
