3pk Oscillating Multi Tool CARBIDE Blades - Universal Fit - by Kaypar Blades - The Essential Blade for Cutting Tough Material like Sheet Metal, Aluminum, and Hardwood with Hidden Nails and Screws

I wouldn't use these on wood. They burn as they cut wood, like a dull blade. Which puzzled me at first because they glide through metal like cardboard unlike the bi-metal blades I had been using previously to cut metal and wood. But then I looked at the blade and realized how thick it is. much thicker than any other blade I've ever used. It does cut wood, but it does so much slower, and burns up the cut, it doesn't smoke up like a dull blade does, but it scorches the cut, and has a burning smell.I still use bi-metal blades as my default general use blade I keep on the tool when stored. But these blades are my definitive metal cutting blades.

bought to trim back some plywood. had just cut about three linear feet with an old steel blade, and thought carbide would work better. these did not. they became dull and smoked the wood within about 3 linear INCHES. proved to be inferior to the ridgid brand ordinary steel blade.would not buy again.

Teeth worn out after cutting two nails.I thought carbide should be more stronger and durable but it is not in this case.As someone said, it is no different than normal Hugh carbo blade so might as well save some money by refiling old one.Blade was never use before test cut of nail. Size of nail being cut (see attached)

I bought theae and a pack of bi-metal blades to cut some roofing nails in a shed. The bi metal blades ended up lasting longer and performing better. The first carbide blade chipped after about four nails. The second blade wore down after a single nail! That’s when I opted for a return. I’m wondering if these are actually carbide.

Awesome blades as usual!! Love em!
