Extreme Demolition

The only blade that would work on a 1-¹/² 2 layer nail embedded subfloor demo job Diablo Demo Demon blades lasted 5' of and were spent, Lenox lasted 15' . I thought that's not good these blades suck I need a serious Demo blade, searched online found the Big Blue order 4, cut for an hour ordered 4 more! Must have a worm drive!

Saw blade

I did roofing all my life and we would have to cut though the peeked and we went through saw blades by the hundreds I bought this blade and I cut though 2 layers of shingles and the plywood it took me about 5 minutes to cut though it all very happy it’s a 10 star

works as advertised.

U.S.P.S held for days and a tracking was done. Smartman tools stood behind and fulfilled making sure I received what I ordered. Excellent business to deal with.

Worked as advertised.

I wish I would have had these years ago. I bought four blades and only used one on the job. Demo’d a complete roof and the blade is still perfectly usable. I bought a hypoid saw (the Makita) to power it – glad I did, I don’t think a standard circ saw has enough snot to power thru.

Anyway – great blade. Absolutely worked as advertised.

Purchased 3T and 5T demolition blades

Delivery went wrong with postal service, company Smartman tools was nice to send the order again right away. Good Customer care. Blades look like they will do the job they are supposed to.
