High-strength 4-in-1 router groove holder built for precision and durability Key benefits - Accurate, repeatable positioning: designed for fast, consistent centering when milling round grooves, cutting round blocks, or engraving round centers. Reduces setup time and errors. - Durable construction: made from high-hardness, thickened aluminum alloy for long service life in demanding woodworking tasks. - Clear measurement readout: oxidation surface treatment and a clearly marked scale make adjustments easy to read and lock in precisely. - Flexible and space-saving: detachable modular design lets you assemble or remove components quickly so the tool adapts to different jobs and storage needs. - Broad compatibility: aluminum alloy modular base can be used as a standalone trimming-machine base or coupled with the slot support for assisted edge milling and round-groove cutting. Main features - 4-in-1 functionality: mills round grooves, cuts round blocks, and engraves round centers with fast positioning for multi-purpose shop use. - Thickened aluminum alloy body: provides rigidity and resistance to wear without adding excessive weight. - Oxidized finish and clear scale: corrosion-resistant surface with easy-to-read markings for precise depth and position adjustments. - Detachable components: quick assembly/disassembly increases versatility and simplifies transport and storage. - Modular base options: mount the base directly on a trimming machine or pair it with the slot support for guided edge work and groove cutting. Performance and suitability - Designed for professional and hobbyist woodworkers who need precise, repeatable round milling and center engraving. - Improves workflow by cutting setup time and delivering consistent results across similar parts. - Suited to a wide range of woodworking materials where reliable alignment and durability are required. Practical use scenarios - Edge profiling and round-groove milling: mount the modular base on a trimming machine and use the slot support to guide consistent edge grooves for decorative trim or joinery. - Producing round dowels or blocks: use the cutting function to form round blocks or dowel stock with accurate centering and repeatable dimensions. - Center engraving and layout: quickly engrave round centers for workpieces prior to turning or assembly to ensure accurate placement. What makes this tool stand out - Combines four related functions into a single, compact tool that mounts to standard trimming equipment. - Robust aluminum construction and oxidized, clearly scaled surface improve longevity and ease of use. - Detachable, modular design adapts the same base to multiple tasks, reducing the need for multiple dedicated jigs. Compatibility and care - Designed to mount on trimming machines; can be used alone or with the slot support for assisted milling. - Keep surfaces clean and periodically check fasteners for tightness to maintain accuracy and safety.
