Product Description

Disc magnets are the most popular magnet among woodworkers, hobbyists and engineers alike. These magnets have hundreds of uses; many of which revolve around the need for a strong fastener that won’t mar surfaces, is reversible and requires little setup time.

They are quickly and cleanly installed into wooden surfaces using a forstner bit and glue (epoxy works best) and their cylindrical shape makes them resistant to accidental chipping.

Nickel Plating: The standard coating for neodymium magnets is nickel. A coating is necessary because the combination of metals that makes up Neodymium magnets corrodes quickly when exposed to air. Some of our magnets are triple coated with Nickel Copper Nickel (NiCuNi) for extra durability.

NdFeB: This specification describes the composition of the magnet, Neodymium-Iron-Boron, to differentiate between magnet types and facilitate further research if necessary.

Grade: The N rating of a magnet is the way those who deal with magnets on a regular basis denote the strength of a particular magnetic material regardless of its shape. The pull force takes into account the geometry of the magnet as well

Maximum Operating Temperature: NdFeB magnets begin to act unpredictably at temperatures above 80°C (176°F). They will lose their (permanent) magnetic properties at around 200°C.
