Choosing Blades

With over 40 accessories for the FEIN Multi-Master just choosing the right blade can be confusing.  Of course many blades can accomplish several tasks, but it is useful to know just what is the blade that does a task best.

what is the best blade for the fein multmaster to cut plaster and lath walls for an outlet.thanks

Hello George,
I would recommend a segmented or full round bi-metal blade. I would use the round blade because with a straight blade you will be often banging into the latch as the saw punches through. Understand that the plaster will dull the blade quickly, but it will cut through with the least dust of any cutting tool.

It may be surprising to you Doug, but that soft gypsum is almost as hard on blades as trying to cut through a sharpening stone.  In fact it is recommended that holes for anchors in drywall be cut with carbide tipped drills.  In fact that is why drywall is cut through the paper and snapped using disposable utility blades. The blade cuts very little gypsum.

Yes the renovation bi-metal blade would be a good choice for any drywall and certainly for metal lathe and plaster.  The blade will wear, but not because of the metal.  The beauty of an oscillating tool for cutting through old plaster walls is that it is as close as we can get to a dustless operation.

Jon...Do you recommend a bi-metal blade for cutting dry wall? My house was built in 1948 (St. Lambert) and in previous reno projects I needed to cut and remove existing dry wall which contained metal mesh in areas. My recip saw metal blade wore out in no time. Looks like the Fein oscillating tool is the ideal tool for this job. I would appreciate your thoughts.
