Segment Magnets With Screw Hole

Sometimes it is necessary to drill holes in segment magnets to facilitate installation. Both through holes and countersunk holes can be made on neodymium segments. We can stably manufacture high-property countersunk neodymium segment magnets of N52, 50M, 48H, 45SH, 40UH, and 35EH. You are welcomed to send us a drawing of segment magnets with the countersunk screw holes.
