Review on Enhance Your Cutting Precision with the Lenox Tools 1211110DGDS Diamond S 10DG by Christian Young

I'm installing railings along my porch and had to drill about 36 holes in porcelain stoneware. Due to the location, I had to drill a few holes using the wrong technique, resulting in them only burning out in a couple of holes. If I used them properly they lasted at least 12-15 holes. There are pictures on the box showing the correct technique, but it's not obvious. Here is the best way following the instructions. 1. Drill a 9/32 hole through a 1/2-3/4 piece of wood. Make sure the piece is long enough to stand or lean on while drilling. Drill the hole close enough to the edge to use as a guide when drilling close to the wall. 2. Align the guide with the marked hole position. 3, Drill deep enough to create a round ring in the tile. 4. Remove the guide and begin drilling AT FULL SPEED, applying as much pressure as possible and filling the bit and hole with water from a spray bottle. This removes debris from the hole and cools the drill bit. The heat doesn't affect the diamond, but it does overheat the glue holding the diamond dust to the steel tip, causing it to loosen. 5. Use an end nail after each hole to remove the tile anchor from the drill bit. If you don't do this regularly, the cork will eventually get stuck in the drill. Instead of penetrating the tile, it then simply rotates in place and heats up. 6. repeat.
