DEWALT 20V MAX* XR Cordless Polisher Kit, Rotary, Variable Speed, 7-Inch, 180 mm (DCM849P2)

I purchased this product and within 30 mins of use, it wasn't working, unfortunately i used this product post 1.5 months, when approached with the authorized service "Screwfix", they said the switch and speed regulator has gone and it doesn't cover under warranty and i had to pay for it.

Good gelcoat buffer. It was my 1st time buffing my boat. Buy good pads, If heavy oxidation start with 3M 5711(white), then 5713 (yellow). If light clean up / polish start with 5733 (blue foam). Keep speed down 500 -700 rpm and check progress by wiping abrasive off until your comfortable. Then start speeding it up...

I have a lot of polishers, from corded Rupes MK3, to Flex corded and cordless versions of XCE, XFE, PEX80. From Dewalt I picked up the cordless rotary and DA. My go to process now for medium correction involving 2 stage (compound then polish) is with the Dewalt Rotary on a 5 inch backing plate with a foam pad. I then finish with Flex XFE.The Dewalt is very effective, I'm happy with the battery life and if you have 2-3 batteries, between polishing and charging you should be able to run continuous. The weight is fine, and vibration levels are acceptable. Between the Dewalt cordless rotary and DA, the rotary is definitely better. This product has become an essential part of my detailing process.

So far, about 4 hours of use polishing concrete with 4" discs. Low speed of this machine was acceptable. Soft start was also useful. Because this is not a purpose-built concrete grinder, the concrete was kept wet separately and the machine was plugged into a GFCI for protection. The two handle options - bale and straight side handles - add to versatility. So far, seems a reasonable low-price option for low volume concrete polishing.

Previously I have purchased 2 Tradespro 7inch polishing machines. Both were complete garbage. Sent them back and spent double the money on this Dewalt. All I can tell is that worth every penny to buy a quality piece of equipment. This Dewalt machine looks very well built. Looks and feels strong during operation. Rpm selector works like dream between 600-3500. Shaft well balanced. Motor sounds strong. Wire also looks heavy duty well rubberized. Very happy with the product especially because it was on sale for CAD189.99 Big retail stores in the nearby offering the same machine for CAD320 so for the price of 189.99 is a very good deal.
