Remind (1) PLEASE READ the description VERY CAREFULLY before you BID/BUY. Remind (2): The 110V Fixed speed Wet Polisher is 600 Watt. It is REAL 600 Watt (some Amazon seller announce their polisher 1200W or 1400W, but it is only 600-800W). This package carries: Wet Polisher+ (9+1) 4" Polishing Pad+ 1 Piece of B20 (3/4" / 20mm) for 20mm / 3/4 Inch high / thick granite marble concrete quartz glass countertop / vanit top edge bullnosing Diamond Brazed Router Bit to do radius / half / roundover bullnose. This package carries (a)-(c). please read carefully before you buy: (a) 1 Piece of Fixed Speed (5000RPM) Wet Polisher (600W, 110V, 5/8" Spindle. with very simple water feed design, designed for users who dont want to spend too much on wet polishing job). This polisher has no GFCI circuit breaker, our advice is plug this into a GFCI normally located in bathrooms and kitchens and using a extension cord from there. It is 5000RPM. 5000RPM is especially designed designed for granite marble concrete polishing. Buyers please note that high speed grinder (like 7500, 11000RPM) are NOT appropriate for polishing since they burns the polishing pad and breaks the pad holder. The hose connector can simply and easily connect to garden hose. Low RPM make this polisher very good for polishing, but it is not very powerful. Please use it softly. (b) 9 Pieces of 4" Diamond Polishing Pad for concrete marble granite and 1 backer/pad holder. The 9 pads are: 2 X Grit 50, 1 X Grit 100 200 400 800 1500 3000 10000. (c) 1 Piece of B20 (3/4" / 20mm) for 20mm / 3/4 Inch high / thick granite marble concrete quartz glass countertop / vanit top edge bullnosing Diamond Brazed Router Bit to do radius / half / roundover bullnose. The inner hole of this router bit is 7/8" to 5/8". it works with the polisher, since all our wet polisher had the lock ring nut pair to use 7/8" or 5/8" non threaded diamond tools.
