If you carefully read through my Dewalt post-2015 media event power tools preview, you would have caught brief mention that Dewalt was coming out with a slew of new angle grinder accessories.
To be perfectly honest, I missed much of what was said about these new cut-off wheels and flap discs, other than “better,” “lasts longer.” I’m sure that “high performance” was thrown in there too, maybe even “faster cutting performance,” but I can’t be certain.
Well, a whole slew of new Dewalt XP ceramic cutting wheels and flap discs just popped up on Amazon.
I don’t remember much of the how’s or why’s, but the demo did seem to show impressive longevity – that much I remember seeing. On the table were spent cut-off wheels from earlier demos, meant to show that the new Dewalt cut-off wheels certainly did outlast competitors’.
The next time I need to do some cutting, I’ll likely buy one of these new Dewalt XP ceramic cutting wheels.
I have a couple of Dewalt cut-off wheels already in my power tool accessories box, but I’m sure they’re expired by now. Yes, abrasive wheels expire and should not be used past the marked date.
If you decide to try one for yourself as well, check the description on Amazon. One of the 4-1/2″ cut-off wheels is described as Type 27 (offset) when it’s really a Type I (flat).
The 4-1/2″ cut-off wheels are pricey, at ~$9 each. They’re also a little thicker, at 1/16″ (0.0625″) compared to 0.045″ for a lot of general purpose metal-cutting wheels. But if they last appreciably longer, then the extra investment might be worth it.
As for the Dewalt XP ceramic flap discs, I know nothing except for Dewalt’s claims, which is that they perform 50% faster and last 2.5 times longer than the brand’s standard flap discs.
The 4-1/2″ discs are priced at around $10 to $12.50 each.
According to the Amazon product descriptions, the cut-off wheels are made in Canada, and the flap discs in Argentina.
