Description:
Traditional permanent magnetic chuck has low accuracy, insufficient magnetic force, and difficulty in removing the workpiece. Look at our permanent magnetic chuck. It is made of high-quality material with strong hardness and good corrosion resistance. With a removable handle and simple structure, it is easy to operate. The strong and uniform suction force allows you to use it confidently. With it, the milling or grinding work will be easier.
Features:
Simple Installation: We considerately provide two screws, two pressing plates, and a handle, and they allow you to quickly complete the installation and start to use it.
High Precision: The high-quality brass panel with a special magnetic circuit ensures smooth milling or grinding and improves its accuracy(0.0004").
Strong and Uniform Suction Force: High-performance magnetic steel is used in the magnetic disk, which has a large suction force(130N/cm²), and the magnetic force is spread evenly, with a magnetic pole pitch of 0.02+0.04in, improving the working efficiency.
Effortless Cleaning: The premium material, smooth surface, and simple structure allow you to simply wipe the product with a wet cloth.
High Safety: Without power supply requirements, the mechanical switch can avoid the risk of magnetic force loss and work detachment due to power failure midway.

Like many inexpensive tools manufactured and delivered from Chinese manufacturing companies, this magnetic chuck will require some work to be useful in your workshop.If you do not have access to a reference surface plate,decent precision metrology, a decently true surface grinder or the skills to mechanic-blue/scrape, this might not be for you.The one I ordered arrived quickly enough, but the packaging consisted only of a poorly taped up cardboard box. It was delivered (roughly, and not by any fault of the manufacturer/seller) on a cement porch, and damage was evident. Had the chuck been in even a thin plywood box, the edge/corner dinging damage would probably have been avoided.The device is very solid, and the actuator mechanism is positive and the magnetic field is quite strong, I can forsee it being able to handle workholding for any material able to sit within the confines of its 5"x16" face.That being said, the base (machine oriented) surface finish is quite good (after aggressively file/die-grind removing the delivery induced dings and edge burrs); however, the surface (tool oriented) finish is quite unremarkable. It will require a fair amount of work to get it into suitably usable shape.The construction of the surface is a typical lamination of stainless/mild with copper brazing (and quite nice), but the top plate seems to have missed its final grinding, as it's obvious when you run a finger across it that there's probably 1-1.5 thou worth of misaligned poles in random locations across the face of the surface.If you have access to a surface grinder, it will clean up nicely with one or two light passes. Bluing/scraping might be a little more work, but is easily do-able.
