Review on 💎 DEWALT DW5572 4 Inch Diamond Drill: Unleash Precision and Power in Your Projects by Robert Espinoza

I recently tiled a new shower cubicle and needed to drill through the porcelain stoneware to attach the glass wall fixings. A few tips 1. Be patient. Don't rush or push. Just keep the pressure on and let the bit do its job. It takes a few minutes to drill just a 1.4" tile, but the end result is excellent.2. Keep the end of the bit wet. Just like cutting tile with a regular wet saw, this bit needs to stay wet to stay cool. You get a better hole and longer bit life. I simply held a damp sponge over the chisel and occasionally squirted scalding water on it to keep it wet. This is perhaps the most important piece of advice. Make yourself a stencil so the bat doesn't slide over the tile onto you. Porcelain is very hard and usually very smooth. It's almost impossible to just place this drill bit on the tile and start drilling without moving to the right. To solve this problem I took a 6" piece of 1x4 scrap and used a regular wood drill bit to drill a 1.4" diameter hole in it. Then I pressed this piece against the wall and put a diamond drill bit in the hole. I was able to hold the jig in my left hand and the drill in my right. This still held the bit long enough to create a nice circular groove in the tile. I was then able to remove the template and just leave the diamond drill bit in the groove. It worked great.
