User questions & answers

Question:	Is this to be used with a hammer drill
Answer:	Probably depends on whether you've used it for water stones or oil stones. If you used it for water stones, warm water and stiff brush may work to some degree. If used for oil stones, some degreaser and a wire brush might work. If it's really that clogged up, you may have already gotten your money's worth from it.
Question:	How many 4” deep hole in new light weight concrete with wire can I expect
Answer:	Yes, this is a very coarse flattening stone. It will leave deep scratches in even a 2000 grit stone. I recommend using a diamond flattening stone for your 2000 grits and up. I use DMT W250FC-WB DuoSharp Bench Stone Fine / Coarse with Base to keep my finer grit stones flat. It's great.
Question:	Do I need a Pilot bit for this drill bit
Answer:	This product is made in China.

User questions & answers

Question:	Can this be used on a hilti model dd 150-u machine
Answer:	No unfortunately it doesn't. You could put it in a bug sprayer and achieve the same effect.
Question:	So what is a 5/8 11 thread? Do I have touse a threaded rod in my 1/2" drill, to be able to use this bit? I can use a garden hose for water
Answer:	I would not use it for that! Concrete is far to abrassive and would eat your wheel up in minutes. You can more that likely get Non Caustic type remover for such needs. Hope this helps....
Question:	what is the recommended rpm
Answer:	I don't see why not. It easily took a large decal off the back of my car without any scratches on the car. I would definitely try on tub.
Question:	what size is the adapter thread
Answer:	It will work well on stainless steel, but if it has a grain or rough texture, the wheel will wear out prematurely. The wheel works like an eraser and wears itself down while also removing the decals and glue residue. I removed decals from my van which had been there more than 6 years. I had tried everything before and nothing worked. This wheel is amazing.

User questions & answers

Question:	can I use this bit with a SDS drill
Answer:	I haven't personally used it for this purpose. However, if I'd trust it on a $30k vehicle (aaaand it worked beautifully), I would certainly trust it on this type of project. Just play with the pressure you use. Start off with easy pressure and slowly increase it as needed.
Question:	What's the real inside diameter? Usually the outside diameter is the one of 2" (it considers the wall thickness of the bit
Answer:	I'd start with rubbing alcohol (isopropyl alcohol), 70% or higher concentration. That's what I use to remove sticky residue that accumulates on knife blades that I use to cut through tape on cardboard boxes; or to remove residue from auto windshields after scraping off registration or inspection stickers. If that doesn't do the job, you'll have to move up in severity to something like acetone. But acetone will dissolve some plastics, so test somewhere first.
Question:	Does it include the pilot bit
Answer:	Not recomended for films or wraps. Mostly used on wheels and paint.
Question:	How mouch inch is this 2 inch
Answer:	Yes. But works great.

User questions & answers

Question:	How do you get the cores out? I need to drill ten 2-1/4" holes thru 8" concrete and I don't understand the complete process. Please explain
Answer:	Hi, Thank you for your question. The Revlon Hair Brush is about 8 3/4''. Thank you.
Question:	Will This Drill Bit setup fit into a 1/2" Hammer Drill
Answer:	They last a surprisingly long time. I had one remove double sided adhesive from a boat, about 1/3 life remaining,it's worth the money.
Question:	Do you need to use water while using this bit
Answer:	Sure does,used it on camper decals. Brush on and used plastic scraper. Works great.
Question:	where can I buy the pilot for the 2" sds max
Answer:	Yes,this works on removing decals from both the glass and metal parts of a vehicle.
Question:	Would it drill through rebar
Answer:	No water or chemical remover needed,it simply comes off as the wheel touches the surface of the decal. It works quite well.I used it to remove a baked on roof wrap with no issues.
Question:	Can I hook this up to a grinder witha 5/8" thread
Answer:	NO.
Question:	Will this fit in a cordless drill
Answer:	can't visualize using a buffing machine, i don't know how you would attach it to a puffing machine. A 3/8 drill motor is your best bet, works, works very well
Question:	Is the 1.75" outside diameter? What diameter core does it recover
Answer:	NO! Plastic absorbs heat. Metal disperses heat. If you get the RPM up enough for this to effectively remove decals, you'll also exceed the temperature at which the plastic will start to break down. You'll dig into that plastic so fast! I've used eraser removal wheels for years professionally. They are amazing on metal! I've tried removing decals from plastic parts and it's almost impossible to get the decal off without digging into the plastic. Go slow, use slow speeds (rpm), and keep moving. You might not damage the plastic, but doubtful. Safer to very carefully use a heat gun and tons of patience. (And if you even think about using razor blades I can't be your friend. 😁😑)

User questions & answers

Question:	Can I use this with a standard cordless, or corded drill without need of an adapter? By wet, I assume you just need to keep water flowing around hole
Answer:	Of course, except for serrated knives and ceramic knives
Question:	will it cut through steel rebar in concrete wall
Answer:	No problem, there are detailed instructions for use inside, equipped with angle guide and honing guide, you only need to apply force
Question:	Will this bit work for hard rock
Answer:	No, it must be soaked in water for 10 minutes before use. During the sharpening process, it is important to sprinkle water to keep the stone moist. Do this as soon as it gets dry. You have to keep a layer of water on the stone. The mud is made up of water and some metal dust produced when sharpening the knife. Do not wipe it off during the sharpening process, as this will help sharpen the knife. Don't use oil on this stone, because you will ruin it.
Question:	What shank size do I need for the three inch drill bit? Do you use this drill bit with a impact drill
Answer:	I haven’t noticed static as an issue.but I only have this problem in the winter.

User questions & answers

Question:	how does it attach to drill
Answer:	I would suggest honing oil if you have it available, I've used water but the oil seems to be more effective.
Question:	How long is the bit
Answer:	3 different grits: * Coarse 325 grit (45 micron)-Quick sharpening the dull & damaged blade or reset the edge on your knife blade or tool. * Fine 600 grit (25 micron) for a sharp edge. It is for everyday sharpening. * Extra fine 1200 grit (9 micron) for honing. Polish an edge to a razor sharp finish.
Question:	what is the thickness of the diamonds pads
Answer:	Yes. As it is made of industrial monocrystalline diamonds, which are the hardest sharpening abrasives, it can sharpen / hone edged tools made of hard material including carbide, high speed steel, ceramic and most of other super hard material.
Question:	Is the 1in diameter the ‘cutting diameter’ or ‘whole-bit diameter
Answer:	Thank you for your question. We would really need to try a sample in order to know for sure. If the canvas is too dense it will not cut through but if it is too thin it could pull when the rolling head goes to slide through. If you would like to send us a piece we would be happy to test it for you. Dahle North America attn: Sample/Customer Service 49 Vose Farm Road Peterborough, NH 03458. Please be sure to include a way to get in touch with the results.
Question:	What adapter and pilot combo would I need to use this bit with my Bosch hammer drill
Answer:	According to the product description its capacity is "30 sheets." I measured our office paper and that's about 4mm, or about 1/8 of an inch. The description I found of the replacement cutting head for the 440 said that it cuts up to 7 sheets of paper at a time, so it might require 4 passes.
Question:	Have dewalt spline hammer drill & a sds adapter for small bits & hd milwaukee right angle drill which to use for 8" concrete

Question:	Need a 2 1/2 hole in street curb for drainage pipe, curb 6 - 6 1/2 inches thick, have Dewalt dwe4011 angle grinder w/ 5/8"-11 spindle, will this do it
Answer:	While there is no guide to show where the blade is going to cut, on the rolling style trimmers it is very easy to see where the cut will be. It is just beyond the clear plastic clamp that the paper slides under. You can roll the cutting head slightly toward your material and see where that exact cut will be.
Question:	I have an sds max bulldog drill. What adapter do I need for this Bit

Question:	Will this cut through granite
Answer:	I uesd it for drill granite,the deepth of core is about 2'',but I think it can be drill more.
Question:	Will this cut through granite
Answer:	This particular SKU has a 5/8"-11 connection. If you want to use an SDS plus drill (rotary only mode), please use this one instead for the right connection: https://www.amazon.com/dp/B07LCXCFD7?ref=myi_title_dp We do advise caution when using SDS connection on bigger diameter core bits, because the small size of the SDS connection can often twist the adapter. If you have 1/2" chuck or SDS MAX drills, those are often preferred over SDS Plus drills.
Question:	will it cut through rebar in concrete wall
Answer:	It's unlikely this 5/8"-11 arbor will fit a hammer drill, but it does, you sure can. Remember to turn the hammering mode off. Other likely connection that might work for you: 1/2" chuck connection: https://www.amazon.com/dp/B01NAYIEZG SDS plus connection: https://www.amazon.com/dp/B077R5QRJN SDS MAX connection: https://www.amazon.com/dp/B07QDQ13TK
