13 best surface grinding wheels

Surface grinding wheels are abrasive wheels used for precision grinding of surfaces. They are commonly used in manufacturing and metalworking to achieve a smooth and flat surface finish on a workpiece. These wheels consist of abrasive particles bonded together with various materials to form a rigid and durable grinding tool.

Key features of surface grinding wheels:

  1. Abrasive Material: The choice of abrasive material depends on the type of material being ground.Common abrasive materials include aluminum oxide, silicon carbide, and cubic boron nitride (CBN).

  2. Grit Size: The grit size of the abrasive particles determines the finish of the surface. Coarse grits remove material quickly, while finer grits provide a smoother finish.

  3. Bonding Material: The abrasive particles are held together by a bonding material. Resin, vitrified, and metal are common bonding materials. The choice of bonding material affects the wheel's hardness, porosity, and strength.

  4. Wheel Structure: This refers to the spacing between the abrasive grains in the wheel. Open structures are used for softer materials, while closed structures are suitable for harder materials.

  5. Wheel Shape: Surface grinding wheels come in various shapes, such as flat, cup, and dish. The choice of shape depends on the specific grinding application.

  6. Diameter and Thickness: The size of the wheel is crucial for achieving the desired surface finish. Larger wheels are suitable for larger workpieces, while smaller wheels are used for precision grinding.

  7. Safety Considerations: Users should adhere to safety guidelines when using surface grinding wheels. This includes wearing appropriate personal protective equipment (PPE) and ensuring that the wheel is properly mounted and balanced.

Regular maintenance and proper usage are essential for the longevity and effectiveness of surface grinding wheels. It's important to choose the right wheel specifications based on the material being ground and the desired surface finish.

User questions & answers

Question: Will this fit the bosch 4-1/2-inch angle grinder 1375a
Answer: If you read the product description you'll see that it says 'Food Grade BPA Free'
Question: What is the height of the wheel, as viewed with the grinding surface down? I need to fit a dust shroud, so I'm looking for a 3/4" height
Answer: The bottle and caps are reusable, but the tamper-proof rings are not. Once they are separated from the cap, they are no longer of use.
Question: What is the maximum RPM for this wheel
Answer: I would not put these into a microwave. They look like the type of plastic that would warp and possibly shrink. I wouldn’t put them in the dishwasher, either. Hand wash only.
Question: Whats the grit difference with color difference

Customer Stories

My husband and I are working on updating our front porch! Easter weekend plans - No one we knew had the tools needed to grind down the cement pad to repaint it properly! Looked at the tool rental department of the big box store and would have easily cost 150+ to rent what we needed. And then.. I thought. CHECK AMAZON! And I did. These were the first go to and I purchased two for safe measure!

Customer Stories

Very impressed with the diamond wheel. I thought I would need to buy more to finish the patio but there is plenty of material remaining on the wheel. It took approximately ~8 hours to grind the paint off of the patio with measurements of 11’ X 16’. The end results is a smoother concrete finish then the “broom” finish of the unpainted surfaces. The final concrete is closer to a steel finish found in warehouse floors.

How to Use It Properly?

1. Strictly follow the instructions in the machine manual.

2. Do not install a diamond dish/cup wheel that is too loose or too tight on the flange.

3. Tighten only with the tool provided with the machine.

4. Be sure to hold the wheels properly to prevent slipping, but do not use excessive force. Never use a hammer.

5. Keep flanges and threads clean without burrs and rust.

6. Before installing the wheel, please replace the deformed or damaged flange.

User questions & answers

Question: Does it fit on a 5/6 arbor
Answer: We recommend our 4-1/2" double row diamond cup grinding wheel for dry grinding of concrete and other masonry materials.
Question: Does this fit a 5/8 arbor
Answer: This has a threaded 5/8" arbor for a hand grinder. You will need a large 3/4" drill and an 5/8 arbor. I wouldn't recommend it.
Question: What is the overall height specification of the wheel
Answer: Yes. When the 4 inch was too small for my project I purchased a 7 inch grinder, grinding wheel, and shroud through amazon. The 7 equipment is a significantly larger investment than the 4 1/2. 7 inch equipment: Grinder - DWE4557, floor grinding wheel - DW4775, and shroud DWE46170.
Question: Will this disk fit on a 7/8 arbor

Question: Will this wheel fit or work on my Dewalt D28402 grinder
Answer: Well is 4 1/2from the bottom at the top. But i think is 5"
Question: I have a concrete wall that’s really rough.many areas have 1/2 pitting and wanna smooth out. Will this work better than a regular grinding wheel
Answer: No it will not, My angle grinder had a 5/8 arbor it fit well
Question: The speed rating of the wheel is 9000 rpm max. So it will not work on almost any non variable speed angle grinder. What tool do you use to drive it
Answer: Yes it should fit just fine. It is a grinding disc for a 4 1/2 inch angle grinder. I am using mine on a Ridgid 4 1/2 inch angle grinder with a 5/8 inch arbor which is pretty much the standard size arbor. If you are gong to be grinding concrete I would look into finding out if there is a dust shroud for your angle grinder that can be hooked up to a shop vac as grinding concrete will make an unbelievable amount of dust. Also it is imperative that you wear a good dust mask to protect your lungs.

User questions & answers

Question: Has anyone used this on a central machinery (harbor freight) bench grinder? Does it fit the arbor and does it cut down some of the vibration? Thanks
Answer: I've only used this on stone wheels. I do not have silicon carbide wheels to test but I imagine the life would be significantly reduced from what it is.
Question: Would this work wih Dewalt 8" bench grinder
Answer: It should true the wheel just fine.
Question: Can you remove the arbor bushing to make this a 1 inch through hole
Answer: This is a dressing tool for grinding wheels. Hold it up against the grinding wheel while its spinning and push with light pressure to clean out the build up af debris accumulated in the grit of the wheel. It also helps "true up" or even out the grinding wheels surface. Should be used daily to keep wheel from burning the surfaces being ground. The diamonds are harder than the grit and open it up for cooler, faster, cleaner grinding.
Question: Would this be considered a fine grit for grinding/sharpening lathe tools? What grit is medium for that purpose
Answer: Yes, it does. Perfect.

User questions & answers

Question: what is arbor size
Answer: its a pretty universal item. Only concern would be your shaft diameter. Check your specs and compare.
Question: what about inner hole size
Answer: This wheel does not have an arbor bushing. It goes directly on the arbor.
Question: Is there something with a wedge or pyramid shape edge for widening concrete cracks for filling with calk (Vulkem
Answer: Every turner has their preferences. I've been doing it for 12+ years. To me, 120 is a relatively fine grit, 80 is medium, and of course 60 to 40 is real coarse. I only use the 60 or coarser if I goof up the edge on a tool and it needs a little reshaping. Whether the wheel is rated as a wet wheel or not, I still spray the tool with water while sharpening. The less heat on the tool the better. Just like the slower the rpm you turn at the better it is for the tool edge.
Question: What is the grit size
Answer: Chainsaws are usually sharpened with a dedicated machine or with a long narrow stone about 1/4" dia by an inch or more long spun in a drill or dremel tool. I bought some these diamond surfaced that work well.g THis dresser should dress the wheel of anything softer than diamond.
