This woodworking circular milling positioning support is compatible with edge trimming machines, chisel machines, and hole drilling machines. The aluminum alloy material has clear markings, and the knob can adjust the processing radius. The locking mechanism is stable and does not shift easily. The base sliding groove facilitates equipment installation and is suitable for woodworking workshops and DIY projects. Before processing, be sure to lock the knob and secure the workpiece.

Made entirely of aluminum alloy with an oxidized surface treatment, the tool is rust-resistant and highly wear-resistant, ensuring that scale markings remain clear even after prolonged use in workshop environments. The complete set consists of a main ruler rod, sliding block, locking knob, and base positioning disc, all of which work together smoothly. Multiple black locking knobs allow flexible adjustment of the radius range; once the desired dimension is set, tightening the knob securely locks the scale in place, preventing displacement during operation and minimizing errors caused by dimensional changes.In woodworking, milling round holes and cutting circular grooves have always been challenging tasks that test a craftsman's skill. Manual operations often lead to issues such as off-center drilling, irregular roundness, and significant dimensional errors. This positioning auxiliary guide is compatible with edge banding machines, router machines, and hole-cutting machines, helping to assist in circular hole drilling, milling circles, and groove cutting, thereby reducing the difficulty of manual work.

The base mounting plate features multiple sliding slots for easy machine attachment, compatible with most edge banding and router machines without requiring complex modifications. Simply secure the machine onto the base, align the workpiece’s center point, adjust the scale to the required radius, and proceed with smooth and precise circular milling, hole drilling, or groove cutting.

This tool works effectively on various wood-based materials including solid wood, MDF, and plywood, making it ideal for creating round tabletops, circular holes, decorative wooden contours, cabinet circular grooves, and more. It is suitable for home woodworking, workshop production, and DIY projects.

When using the tool, ensure all knobs are fully tightened before starting, securely clamp the workpiece, and follow standard woodworking safety procedures. While this tool primarily serves as a positioning aid, the final machining results still depend on machine speed, feed rate, and material properties. Its clear and intuitive scale allows quick and accurate radius reading, eliminating repetitive measuring and marking steps, improving efficiency, and reducing the need for repeated adjustments and sanding. It is a practical and reliable assistant for all circular woodworking operations.
