Customer Questions & Answers

will this work on hardened steel?

i have a knife made from 1055, hardened enough that a file won't touch it. i want to reprofile the blade to 4 inches and redo the bevels with this, but i need to know if it will handle the job without wearing down before its finished. the knife was made with 5/32 inch stock if that helps.
Asked by: TheOncomingStorm
It will grind tool steel, if you have the skill to control the grinder. A flap wheel often lasts longer grinding steel than a traditional rigid wheel.

Where do I find a Type 27 disc?

The manual says to use only type 27 depressed center wheels. I bought and returned this the same day not knowing there would be a difference.
Asked by: steve
I have a Bosch Angle Grinder with type 27 discs. I use the Home Depot Flap discs, and also their metal cutting discs. My Bosch is a 5" but 4.5" size works fine. All these discs at Home Depot are marked as Type 27. The key thing is to check arbor size. Mine is 7/8" arbor /shank diameter so I check this on pkg. You can also find these on Amazon. Search on 'Type 27 discs' and you will find them, but why look further than Home Depot?

As much or as little as you need it too. It all depends on how hard you push

Asked by: vacesu9
Technically, yes. It will remove wood, but is very likely to groove the material badly because it is a rigid disc. For wood, used a flexible rubber backed sand disc in an orbital tool.

I was looking for a product that would smooth out some heavy welds on steel frame trailers. This item knocked the time involved for a stone wheel down to a fraction of that. In one instance that required nearly 13 minutes of labor the reduction found it required less than 5 minutes to do the same work. Needless to say they cost more and wear faster than the stone version but for me the time savings and clean look of the finished product justify the continued purchase.

We have an old steel patio table, it's been passed down through the generations. Every so often it needs to be stripped down to bare metal and repainted. This Diablo ultra coarse flap disc is the best thing I've ever used for the job (my third time, next time it will be in my son's or daughter's hands). Sure beats wire brushes and every sander I've ever tried.

Rated 3 out of 5 by from I have a huge need for flap disks to sand out nail embedded reclaimed pallet wood for furniture. ... I have a huge need for flap disks to sand out nail embedded reclaimed pallet wood for furniture. I use my angle grinder to smooth out tops of rough hewn wood. Prior to that, I grind off nails till all that is left is the nail embedded in wood. At this high price I had hopes the Diablo brand would last longer and outshine the 4.5" Harbor Freight Aluminum Oxide (same as these) discs. Nope! These lasted the same amount of short time before they were worn out and burning the wood leaving singe marks on it. Might as well buy the HF brand at $5 each instead of $8! Not much luck on Amazon either. And impossible to find Zirconia flap discs, or even 5" size which is my Bosch grinder size. Not paying this much for mediocrity. I'm also buying a conversion pad and sanding discs for my grinder to replace these costly discs. The Bosch RUBBER conversion pad on Amazon is highly rated, but the sanding discs (not flap) are very reasonable and good at Home Depot.

Rated 3 out of 5 by from So so I have had these wheels in the past that cut good and last long. This one didn't seem to perform as well, especially not for the price you pay. Gonna try some other brands you can buy online for a third of the price.
