User questions & answers

Question: Will the fine disk be enough? I have a piece of juniper drift wood that i want to clean up. Will the fine disk be enough to remove years of gray
Answer: They work on my Dewalt hook and loop sander very well. Used with a vacation, it picks up more fine dust than with sandpaper.
Question: What would i need to mount this on a pneunumatic grinder that has a 1/4 shank? like the dewalt dwmt70782l? or is that not possible
Answer: Mine showed up the same way - Clayton branded box, NSN 20201012. Back side of disks are printed “Mirka Abranet P320”. Disks visually appear to be the real thing and physically feel like the real thing. No other packaging inside the Clayton box or inside the Amazon bag. I almost returned mine before reading this about non-OEM packaging.
Question: Is this disc compatible with a galaxia angle grinder
Answer: I don't believe it's recommended for that but I don't see why it wouldn't. Be careful
Question: will it work on a hitachi 4 1/2” grinder
Answer: Your die grinder doesn't spin that fast. So you are good. Wear eye protection, please.

User questions & answers

Question: will this fit on a 3/4" shaft
Answer: Yes, it will work. It comes with a bushing to fit a five-eights arbor. Make sure the disc isn't touching the gaurd before turning on your tool. If it does touch, remove the gaurd. These tools can be dangerous, use a full face mask, clamp your wood firmly to a stable surface, and hold the grinder firmly with two hands. It's a great tool once you get used to it. I prefer these to the expensive arbortech planers.

User questions & answers

Question: Are these more like sandpaper or Brillo pads
Answer: Might be too much. These disks are very aggressive. Unless you want to re-shape the piece I'd try using sanding mop disks--coarse, medium and fine. They conform to the contours to clean up the piece whilel not altering it's original shape(unless you hang in one spot). It would take a very precise light touch not to alter the contours with the Kutzall.
Question: What is the max RPM these discs are rated for
Answer: their are bushings for such or have a machinist to make one

User questions & answers

Question: Is this a hook & loop type sanding disk (velcro-type attatchment to backing pad
Answer: You would have to enlarge the center hole in order to fit a 3/4 inch shaft.
Question: Is this for use with hook and loop backing pad
Answer: Norton offers a flap disc with a 5/8-11 hub the norton part number is 66261183492
Question: How does sand disc attach
Answer: you have to buy the backing pad and lock nut . What is the make and model of your grinder?
Question: How does sand disc attach
Answer: thank you for the question. When using a fiber disc 60 grit and coarser we suggest a rubber back up pad. Spiralcool Backing Pad is the manufacturer that we sell. if you are using a 4-1/2" grinder the part number is R425-R the pad has a 5/8" threaded center hole. The locking nut which holds the disc in place is SP-103. Spiralcool Backing Pad also offers a backing pad with a 5/8" center hole that is a smooth bore part number R425-5/8SB also using the same locking nut SP-103. Why the difference? Length of the spindle on the tool. also does the tool have the backing flange still on it. Our experience is that we sell more of the R425-5/8SB. If it is a Dewalt grinder they offer part number DW4945 which is the rubber backing pad and lock nut. Metabo also offers a 4-1/2" pad part number 6.23283 which is a little more flexibleand works great on 80 grit or finer discs. Please let me know what manufacturer of the grinder and is it electric or pneumatic and we can provide the proper backing pad.
