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.
