Recently, I found that some Canadian customers are looking for such countersunk magnets. In fact, in addition to Amazon and some local magnet suppliers, you can also choose our Chinese magnet manufacturers, which may be more cost-effective.
Our company is located in Guangdong, China, and can provide you with various properties and grades of countersunk (counterbore) neodymium magnets, ferrite countersunk magnets and samarium cobalt countersunk magnets, including various shapes, you may not have seen them all Oh.
Below are some common types of countersunk magnets to see which one you are looking for.

How do I order this countersunk magnet?
You only need to tell us the magnet material, size, grade (or Gauss), tolerance, magnetization method, purchase quantity, etc. you want, and we will be able to quote and process it for you.
Recently, we have also made several deals with Canadian clients. We look forward to friendly cooperation with you and become your china magnet supplier.
