Versatile: The 20mm clamping element is easy to handle and requires no extensive professional knowledge. It is suitable for a variety of applications such as carving, milling, grinding, processing, and general woodworking, making it the ideal tool for woodworkers. Steel Material: This 20mm lever clamp is made of robust steel to ensure durability and stability, as well as excellent abrasion resistance for long-term use. High Clamping Force: The one-handed clamp easily handles surfaces at various angles and clamps them securely. The self-aligning design adapts perfectly to surfaces with different angles and holds workpieces securely, faster than traditional bench clamps and unaffected by vibration. Easy to Use: The lever collar features a soft ABS pad to prevent damage to the workpiece surface. Simply drill a 20mm vertical hole in the workbench, insert the handle, and adjust the clamping pressure until the clamp is securely fastened. Thoughtful design: The clamping element features a ratchet mechanism to ensure strong clamping force. The quick-release chuck has anti-slip grips to prevent slippage during use.
