Enhanced cutting precision - The tight joint connection technology delivers precise seams for door and window frames and enables accurate 45-degree miter cuts with high precision. Stable construction - Deformation-resistant build with wear-resistant technology and a thickened insulating plate provides extended life even for demanding craft projects. Robust clamping design - Quick positioning system and stable clamping prevent shifting during cutting; integrated calibration marks enhance safety and precision for reliable performance across tasks. Efficient window helper - Specifically developed for window installation, it cuts through wood, PVC, and aluminum. Seamless integration with hand tools or power tools makes it an ideal companion for DIY projects of all kinds. Use scenarios - Installing new door or window frames: achieves precise 45-degree cuts and tight joints for clean finishes. - Renovating or replacing frames: handles wood, PVC, and aluminum with stable, repeatable results. - DIY framing and trim projects: provides reliable clamping and accurate cuts for custom builds.
