What kind of magnets?
From wiki on Neodymium
Neodymium metal dust is a combustion and explosion hazard. Neodymium compounds,
all rare earth metals, are of low to moderate toxicity; however its toxicity has
thoroughly investigated. Neodymium dust and salts are very irritating to the
mucous membranes, and moderately irritating to skin. Breathing the dust can
embolisms, and accumulated exposure damages the liver. Neodymium also acts as an
anticoagulant, especially when given intravenously.
Neodymium magnets have been tested for medical uses such as magnetic braces and
repair, but biocompatibility issues have prevented widespread application.
available magnets made from neodymium are exceptionally strong, and can attract
from large distances. If not handled carefully, they come together very quickly
forcefully, causing injuries. For example, a person lost part of his finger when
magnets he was using snapped together from 50 cm away. Another danger is
when two such
magnets snap together, the force of the collision can cause them to shatter,
pieces flying around, potentially causing serious injuries.
We got a new guy in the shop last year. Sharp as hell. He praise magnets
to the sky for their versatility, and claims once you have tried it you
won't look back. One of these days we're gonna give it a try.
Chips stick to the magnets, pile up around work pieces and eventually
get (re)eaten by cutters. Through hole work? Forget it unless willing to
swiss cheese the magnets and trash tools. Shallow holes? Chips get sucked
to the bottoms of holes and chew up tools. The thinner the workpieces, the
greater the headaches.
Takes a minute or two to bolt a vise to a table and tram it in. Then tool
clearance and rigidity isn't sacrificed by being raised off the table
several inches. Plus no worries about it skittering around from cutting
