Stable metal hold-down clamp designed to keep workpieces secure during cutting, routing, or assembly. Key benefits Secure grip: Robust metal construction provides a strong, reliable hold so materials do not shift during cutting, drilling, or assembly. Broad compatibility: Fits benches and fixtures with 19 mm or 20 mm accessory holes, making it usable across a wide range of workbenches and jig setups. Fast, tool-free adjustments: User-friendly hand-twist (hand knob) quick-adjust mechanism allows rapid positioning and tightening without extra tools, saving setup time. Features and performance Function: Holds stock firmly for safer, more accurate cuts and repeatable assembly operations. Size compatibility: Specifically compatible with 19 mm and 20 mm diameter holes. Material: Durable metal construction for long life and consistent clamping force. Operation: Hand-adjustable mechanism enables fine-tuning and quick release when repositioning is needed. Typical applications Woodworking: Secure lumber or panels on a workbench while crosscutting with a circular saw or using a router to prevent tear-out and movement. Assembly and gluing: Hold frame parts or components steady during adhesive curing or while fastening to maintain alignment. Light metalworking and jig use: Clamp small metal parts or fixtures in place for drilling, deburring, or layout tasks. Why choose this clamp Reduces material movement and rework by keeping parts stable during critical operations. Simple, reliable design that integrates with common 19/20 mm bench setups. Quick adjustments speed up workflow without compromising holding strength.
