Review on SE DH10HS Diamond Hole Saw by Shane Yay

This is amazing! I've had many very nice ceramic and terracotta flower pots with no drainage holes, and no matter what I do, the roots rot and stink. I got these bits, drilled holes in the bottom and now I can use all my lovely pots! I also find a lot of great clearing suggestions when people pass pots with no holes, but since I can drill my own, no worries! It's very easy and I've made at least a dozen already, so here are some tips if you're hesitant to try it yourself: 1. Choose a training kettle first, don't start with great-grandma's antique kettle.2. Go outside or in the garage as chalky water is splashing everywhere. Wear safety goggles or sunglasses to keep it out of your eyes. Turn the pot upside down. Decide how many holes, how big they are (which bits) and where. Mark with a marker if necessary. Just don't make the holes too close together as the area between the holes will be weak and you don't want the entire floor to be exposed. Same goes for the edges, don't get too close to the outside edges. I try to keep the ceramic intact about an inch around the holes, and even more for larger pots. Be careful to drill wet - dampen the surface you are drilling with some water so it doesn't get too hot. Sometimes I put the pot upside down in a bucket of water so deep that the bottom of the pot is barely submerged, or if the bottom of the pot has a hole I just pour some water in. You don't need much, just cover the surface, 1/2 inch will do. Since I'm doing it outside, I just keep the hose close to me so I can add more water if needed. 5. Hold the bait firmly to the bottom of the pot with the bait tilted slightly to one side, not completely flush to allow just the side/edge of the bait to dig a small groove to help you start if the bottom is glazed and slippery or the pot is brittle. 6. Start slow and let the drill do most of the work. If your drill has a fast and slow setting, turn it to slow. 7. Having cut through the glaze (if any) and made a small groove, this will help hold the drill in place until the end of the work. Gradually turn the drill straight so that the drill goes straight up and down, and gradually drill required.8. Don't press very hard, but at the same time you need to hold the drill and gradually apply pressure so that you drill through the pot. With ceramic, you may have to put some of your weight on it. You will quickly get used to it. I do it on my knees with the pot on the floor or in the bucket of water on the floor so that I am in complete control of the situation. Be careful how close you get to the break, because once you do it will be sudden and you'll have to stop pressing immediately, or you could lean forward and slam the bottom of the pot with your whole drill. ten . Gently pull the drill out of the hole. There will be a ceramic plug (the part you drilled out) stuck either in the bit or under the pot. If it gets stuck in the nozzle, just tap something hard with the side of the nozzle and it will fall out.11. Admire your work and start planting!
