This looks to me like a cordless 4-1/2″ angle grinder that spins at 6,500 RPM instead of 10,000+ — which is probably why they call it a “cutoff tool.” That said, the two-position handle looks comfortable and a cordless cutoff tool would be quite handy — assuming it offers a suitably-long run time.
Then again, if anything could offer a long enough run time, I’d imagine it’s DeWalt’s massive 36-volt batteries, two of which are included with the kit. It weighs 7.2 pounds, and includes a spindle-lock for easy wheel changes. The kit also includes a grinding wheel, a cutting wheel, guards for each — which you’re not going to remove, right? — and a “heavy-duty kit box.”
The bad news: street pricing starts around $430 — although we found one retailer selling the tool only for $90, which would make a great deal if you already have one of DeWalt’s 36V tools.
