User questions & answers

Question:	How many grits is the cutting wheel
Answer:	It should but I don’t know for sure. The center tapped hole on the cup should match your grinder as most grinders have a standard thread size. You should be able to check you owners manual for you grinder to find the call out for the thread size.
Question:	Is this model lighter than other Angle grinders
Answer:	Yes I use it for cleaning up plywood floors, cement board, porcelin tile, block, cement etc. It will leave a smooth surface, but not polished. It is an excellent tool. RVKitman.
Question:	Brand new out of box, it turns off immediatly after starting up. Battery is fully charged. Why
Answer:	This diamond cup is great for flattening concrete. It's not good at cutting down a recess in concrete. The edge would round over so your recess would have a fillet. You need another cup to cut square edges.Best way to deal with your situation is to attach a diamond blade to a circular saw. Cut a few grooves 1/2" and knock off the remaining concrete. Or cut some more grooves to remove all the concrete. Then use this diamond cup to flatten the bottom. Cutting concrete is much faster than grinding concrete.
Question:	How is the start switch compared to other cordless grinders
Answer:	It will grind ceramic with no problem. The diamond specks are tougher than ceramic.Be sure to wear PPE. Concrete grinds to dust but ceramic may remain as larger, sharper chunks.

User questions & answers

Question:	How can I tell if this is the brushless version
Answer:	Yes, however this grinder REQUIRES Wheels with 7/8" thru-hole. This is because the back flange and the nut combination... It has a shoulder which serves to precisely locate the grinding disk on the 5/8" - 11 arbor. The diameter of this shoulder (centering ring) is ⅞". If you use the 5/8 in through hole, there will be very little surface touching the discs... Only about ⅛", also the flange nut would tend to Shear the disc - it has a recess which perfectly accepts the shape & diameter of the shoulder.
Question:	Does this have a standard 5/8" spindle
Answer:	Shouldn't have any problems for flat or depressed disks on any contractor grade grinders. Don't have this one but check the key wrench if it could reach deep enough to remove the lock nut. The grinding stones are really deep as with diamond concrete grinding cup wheels. Couldn't find any aftermarket keys with deep enough reach, had to make my own.
Question:	Can depressed center disks be used with this grinder or only flat center ones
Answer:	yes
Question:	Does this grinder include that tool that you change the grinder weel
Answer:	about 10 degrees

Question:	Is included charger dcb1106 rapid charger
Answer:	4.5inch
Question:	Is it variable speed
Answer:	7/8” is the ID
Question:	where is the variable speed control You say it has and why isn’t it mentioned as 0 to 9000 RPM
Answer:	No,no flex of any appreciable degree that I can determine. In fact I'd avoid any attempt to "flex" them to create a tight curve or radius. A guard, gloves and appropriate eye-wear are definitely a must when using ANY cut off wheel.
Question:	Included charger dcb1106 in this kit dcg418x1 is rapid charger
Answer:	I have cut through 1/4 inch just fine, probably would cut thicker
