Dual synchronous clamping: using a worm gear transmission mechanism (transmission ratio 1:50) to achieve a jaw centering accuracy of 0.02mm Multi directional adjustment: supports 360 rotation positioning (indexing accuracy of 5) and 15 tilt angle adjustment, suitable for processing irregular workpieces Clamping range: The standard configuration can clamp boards ranging from 20x20mm to 150x150mm, and the optional extended arm can reach 300mm Product Overview: Through modular design and material , this toolkit can achieve full scene coverage from basic mortise and tenon processing to instrument calibration. Central punch assembly: Three step ladder drill bit: 3/6/12mm quick switching, supports hardwood/metal/plastic (recommended speed of 800-2500rpm) Magnetic positioning system: Built in strong magnet array (suction force equal 8N), ensuring that the drill is aligned with the marked points on the workpiece Anti offset design: Spring reset device reduces vibration offset (measured offset less than equal 0.1mm) Platform drill integrated module: Micro-type motor: 200W brushless motor (torque equal 1.5Nm), supporting 0-13500rpm continuously variable speed Quick change chuck: ER20 spring chuck (clamping range: 3-16mm), tool change time less than equal 5 seconds Cooling system: Built in lubricating oil passage (flow rate 0.2ml/r), extending drill bit life by 3 times.
