Can a dremel cut rebar?

Summerville, SC(Zone 8a)

Can my dremel tool cut rebar? What kind of blade/disk would I need?

Powder Springs, GA(Zone 7b)

I don't think a Dremel is the way to go for cutting rebar - seems like it would take a very long time and you'd have a lot of broken blades. A RotoZip would be a lot better with a metal cutoff wheel and it should be good for small projects.

The fastest way is with an angle grinder and a cut-off wheel.

I think the Dremel could do it, but you probably will go through many wheels and take a long time.

A hacksaw can do it, too, but if you have a lot of cuts to make - it will be a tiring exercise.

Harbor Freight quite often has the 4.5 inch angle grinder on sale for about $20, and all kinds of wheels for $1 to $6. Just bought a back of 10 wheels for $10 that had cut-off wheels, grinder wheels and flap-sanders.

Used several wheels cutting over 100 ft of 3/8 rebar a couple of years ago. Started with a recip saw and metal cutting blade, but it was slow and destroyed the blades pretty fast. Only took seconds with the angle grinder.

Thanks for your replies .. as I understand it, all I have to do is cut half way through and I can bend it a break it off. Is this correct?

Powder Springs, GA(Zone 7b)

I'd say you have to cut almost all the way through. Rebar is pretty tough to bend even with cutting halfway through (as I remember it). I used my RotoZip but an angle grinder like Bubba mentioned would probably be a stouter tool if you had to do several rebars.

If you had a lot of rebar to cut I'd rent a rebar cutter (maybe HD rents a tool like some of these pictured in the link).

Here is a link to Harbor freight - there is one 4.5 angle grinder for less than $19. You would probally spend more renting a manual cutter.

Sigh .. I only need to cut 3 ten foot pieces in half - I'm thinking maybe if I go on and buy it, see if I can find a construction site and they may cut it for me.

A circular saw with a metal blade will also cut that rebar. If you buy it, they might be able to cut it for you.

I already asked if the store would cut it and they said no. Next time I go I'll check out metal blades for my saw and see about the angle grinder.

Why not just buy shorter lengths? Not sure if they come in five foot lengths but I'm pretty sure they come in four and six foot lengths. They do make for some good stakes.

A masonary blade for your circular saw will do it - get as thin a blade as you can - should be about the thickness of the saw blade. Be sure to secure the rebar and cut straight to prevent breaking the blade and let the blade make the cut - don't force it.
One other word of caution - the cut ends will be HOT! Wear gloves.

If you know anyone that has a metal chop saw goes thru rebar in two minutes.

A welding bus. might have one or a cement contractor as they are often used to reinforce concrete when they pour it.

We have one but we are too far away.

Ever thought of a good old fashioned hacksaw? Slow, but it works. Personally, I use a reciprcating saw with a metal cutting blade. BTW, Lowes sells short lengths, I buy them all the time.

Thanks to everyone for suggestions .. I just happened to stumble upon a site that says use a masonry blade in my circular saw - so off to home depot for a masonry blade and rebar!

EYE PROTECTION.........with masonry blades and metal for sure
