Fine adjustment accuracy of 0.01 mm: enables precise trimming and slotting with minimal guesswork, reducing errors and waste. Aluminum alloy material: CNC machined aluminum alloy provides durability, stability, and longlasting performance during use. Convenient reset scale: easily reset the finetuning scale to 0 before each operation for repeatable, consistent measurements. Efficient cutting operations: align the work with the reference line along the board edge, lock the position, and translate at a uniform speed for accurate cuts. rotate the handle to set the feed amount and lock it for repeatable results. Use scenarios Cabinet and furniture fabrication: trim panels to exact widths and fit components without gaps. Joinery and grooves: perform precise groove or slotting operations with repeatable depth and alignment. Repetitive production in a workshop: set up once and execute identical cuts across multiple boards with consistent speed, depth, and position.
