DescriptionThis is a permanent magnetic chuck. It is a magnetic fixture widely used in machine shops, mold factories, and other machining fields, and can greatly improve the efficiency of magnetic steel material clamping.FeaturesExcellent Magnetic Force: We used a high-quality magnet with a high-security factor to providing super strong magnetism for you. Sturdy and Durable: This magnetic chunk has a special design internal, which makes it more reliable, lasts longer, and can attach tightly. Easy to Use: A handle controls the machine's on and off, as well as the attachment and detachment of material. During demagnetization, the work surface's accuracy remains unchanged.Long-service Life: The panel has been professionally treated and has no leaks, preventing the cutting fluid from corroding and extending the magnetic disk's service life.High Precision: The main structure is precise and sturdy. The magnetic force is equally distributed and the magnetic pole pitch is 1.5+0.5 mm.Mechanical Switch: There is no need to connect electricity. You can open or close it with the handle. So it is convenient, flexible, and durable.Top Plate: The top plate is a solid, one-piece item, which can protect it from dirt and fluids.Application: It can be used with surface grinders, tool grinders, EDM machines, and other things.SpecificationModel: 15 * 30cm(6”x12”)Chuck Height: 4.5cm(1.77”)Pole Pitch: 0.5+1.5mm（2mm）/0.08”Copper Strip Length: 26cm(10.24”)Copper Strip Height: 2cm(0.79”)Net Weight: 18.5kg(40.79lbs)Product Size: 30*15*4.5cm(11.81*5.90*1.77in)Package Included1 x Magnetic ChuckAll Accessories for Use
