N52 Small Neodymium Disc Magnets 3x1mm (1/8 x 1/32 inch) - Tiny Flat Rare Earth Magnets for Tabletop Miniatures, Wargaming Weapon Swaps, Infantry Scale Models (100 Pack) Review (2026)

Who these tiny magnets are for

This pack targets tabletop painters who want to swap weapon arms, heads or wargear options on 28mm scale miniatures rather than gluing everything permanently. At 3mm diameter and 1mm thick, the discs are small enough to sit flush inside a hole drilled with a standard pin vice into a plastic or resin arm socket, which is the usual size used for Space Marine, Stormcast and similar infantry scale kits. A single army of 20 to 30 models with a couple of magnetized points each will use up a large share of the 100 count pack, so this size suits a focused magnetizing project more than someone planning to convert an entire large collection at once.

Grade, plating and how the size works in practice

N52 is the strongest commercially available neodymium grade, which matters at this small size since a thinner magnet needs the extra pull to hold a weapon arm steady during a game. The discs carry a triple layer nickel copper nickel plating that resists chipping and will not scratch a painted model when parts click together. Because they are only 1mm thick, the socket does not need to be drilled very deep, which helps on smaller models where a deeper hole risks going through the part. Painters usually pair one magnet in the arm with a matching one in the torso socket so the piece seats flush and swaps cleanly between games.

Fitting them into a magnetizing workflow

Using this pack means drilling a 3mm hole with a pin vice at the joint you want to swap, test fitting the magnet so it sits flush rather than proud of the surface, then gluing it in with a small drop of cyanoacrylate. Getting the polarity consistent across every arm and torso pair takes a bit of care early on, since a magnet installed backwards will repel instead of attract. Once set up, swapping a bolter for a plasma gun or a sword for a shield takes seconds, which is useful for players who want one squad to represent several different loadouts without buying and painting duplicate models for each option.

Where the pack size and strength become a trade-off

Because these magnets are quite strong for their size, they also snap together forcefully when stored loose, which can make sorting a small pile of them fiddly, and pinched fingers are a common complaint with any magnet this strong. The 100 count pack is generous for a single infantry squad project but will run out quickly if you are also magnetizing turret options, weapon sponsons or interchangeable heads across a larger vehicle heavy army, where a 500 pack such as the NiCuNi plated option from the same size range stretches further per dollar.

Verdict and who should buy a bigger pack instead

For a painter magnetizing a single squad or a handful of characters with weapon options, this 100 pack of 3x1mm N52 discs is the right size and strength, sitting flush in a standard drilled hole and holding firmly during games. Anyone planning to magnetize a whole army with multiple swap points per model, including vehicles with several weapon mounts, should size up to a 500 or 1000 count pack from the start rather than reordering partway through a project, since buying in bulk tends to work out cheaper per magnet.
