neodymium magnets on other surfaces using double-sided tapes. Unfortunately, not all surfaces are suitable for using double-sided tapes.\u00a0<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">In general, it is best to use double-sided tapes on smooth, non-porous surfaces that are relatively flat and stable. This will help to ensure that the tapes form a strong and durable bond. Meanwhile, there are several surfaces that are not well-suited for using double-sided tape. Therefore, we will\u00a0 make countersunk neodymium magnets for you to fasten them with screws.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Below are some surfaces that are not suitable for double-sided tapes.

If you use a large drill bill to make the hole in one step, the neodymium magnets are fragile, and they may crack. So, we prefer to use a small drill bit first and then use the big one.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Keep the drill bits sharp. If a drill bit is dull or damaged<\/span><span data-contrast=\"auto\">, <\/span><span data-contrast=\"auto\">it can cause the<\/span> <span data-contrast=\"auto\">hole to be uneven or jagged, and even leave burs on the edge. This will have a negative impact on the function and appearance of the countersunk holes<\/span><span data-contrast=\"auto\">.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Use low<\/span> <span data-contrast=\"auto\">speeds<\/span> <span data-contrast=\"auto\">for the drills to prevent neodymium magnets from overheating. High<\/span><span data-contrast=\"auto\">&#8211;<\/span><span data-contrast=\"auto\">speed<\/span> <span data-contrast=\"auto\">drilling can cause the neodymium material to heat up and become brittle.

There are multiple factors contributing to the quality of countersunk holes in neodymium magnets. Some of the most important factors include:<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">The diameters and angles<\/span><span data-contrast=\"auto\">: <\/span><span data-contrast=\"auto\">Countersunk holes should have correct diameters and angles to fit<\/span> <span data-contrast=\"auto\">the screws that will be used. If the holes are too small, you can\u2019t insert the screws smoothly. If the holes are too big, the magnets may shift a little bit. If the angles are not right, fastening the screws can make the magnets crack or break.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">The positions: The holes should be accurately positioned in<\/span> <span data-contrast=\"auto\">neodymium magnets.<\/span> <span data-contrast=\"auto\">In this way, you will be able to insert the screws straight into the magnetic assemblies. If the holes<\/span> <span data-contrast=\"auto\">are not aligned properly, this can cause the screws to bind or be difficult to assemble<\/span><span data-contrast=\"auto\">.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">The smoothness: The edges should be smooth and have no burrs or rough spots<\/span><span data-contrast=\"auto\">. <\/span><span data-contrast=\"auto\">These minor defects can cause screws to bind or reach<\/span> <span data-contrast=\"auto\">the correct<\/span> <span data-contrast=\"auto\">positions<\/span><span data-contrast=\"auto\">.\u00a0<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">The depth: The depth of the holes<\/span> <span data-contrast=\"auto\">must be<\/span> <span data-contrast=\"auto\">correct for the length of the screws. The holes should be deep enough for you to<\/span> <span data-contrast=\"auto\">fully insert the screws<\/span><span data-contrast=\"auto\">,<\/span><span data-contrast=\"auto\"> so they may not cause gaps between the magnet surfaces and magnetic assemblies<\/span><span data-contrast=\"auto\">.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p><p><span data-contrast=\"auto\">Osenc people will do our best to assure the quality of countersunk holes.
