The promise of the Dual Saw is two blades rotating in opposite directions, which in theory should eliminate kickback and halts on stubborn material. Claims of cutting through steel tanks, drums, flooring with nails etc. Anyone use one?

Amazon link here: http://www.amazon.com/DUALSAW-TwinCut-Counter-Rotating-Attachment/dp/B005ZG6DOQ/ref=sr_1_1?ie=UTF8&qid=1345589877&sr=8-1&keywords=dual+saw+cs450

  • I haven't used one, but I've had one in my hands - it's a scary looking sumbitch for sure.

    But in reading about it, maybe it's good at making clean cuts in hard metal. Can anyone comment on using it on Unistrut or 5/8" threaded rod? How do metal cuts compare to those from the likes of the $450 Makita LC1230?

    For example, compared against abrasive chop saws (very messy) or portable band saws (can be difficult to cut straight & clean), too. Or even comparisons to plain recip saws?

I also haven't used this guy, but here, in short, is what the guys at Toolmonger said:

(For their complete answers, search for "dual saw" at toolmonger dot com.)

  • Cuts okay, with surprisingly clean edges.

  • Incredibly noisy.

  • When cutting metal, throws large, hot chips in two directions.

  • Depth of cut is limited to 1" with 5" blades (so it can't cut framing lumber in one pass.)

  • Cuts a very wide kerf (no mention of how wide though.)

  • Jerks unpredictably in both directions.

  • Possibly no better than a 5' angle grinder (which does pull, but only in in a predictable direction.)

  • Possibly made by a company that got many BBB complaints under its previous name, Infusion Brands International.

  • Doesn't come with a cutting guide, so out of the box you have to cut free hand.

  • Accessories and blades are expensive.

Hope that helps!

For light work an inexpensive one will serve you well and anything that Home Depot sells should work well. If you need the extra power from the grinder, there are many to choose from online which will serve your purpose.

I think you're best bet is to walk into a hardware store that specializes in power tools and get the most knowledgeable guy in the joint to assist you. I've been kind of looking for the same thing and found that angle grinders will give you the type of power you've always dreamed up with power up to 11000 RPM. http://bestanglegrinder.net/getting-your-hands-on-the-best-cordless-angle-grinder/
