Works great. No complaints.

### ⭐⭐⭐⭐⭐ So you want to drill a hole...
*by L***D on May 11, 2023*

... and you're looking at this product wondering if it can help you do it. The answer is YES but you will need to buy some extra equipment. I had to drill a 2.75" hole through about 12" of VERY HARD brick and this thing did the trick. Here's what else you need to buy: * #16 SDS Plus (TE-C) to 1-1/4" M Core Bit to Drill Adapter by BLUEROCK Tool * Diablo 1/4 in. x 16 in. x 18 in. SDS-Plus 2-Cutter * BOSCH 11255VSR Bulldog Xtreme 8 Amp 1 Inch Corded Variable Speed SDS-Plus Concrete/Masonry Rotary Hammer I know what you're thinking: can I get away with just a normal drill? Answer is NO. I tried a regular drill and a regular hammer drill but become extremely frustrated quickly. The long pilot bit is really critical for when you get stuck deep in the hole. Get the core bit back out and send the pilot bit through several times. Other important tips: * Use the hammer mode. I know it says all over this page not to do that but I couldn't make any progress with out it. Used hammer mode and everything was fine, drill bit is still in great shape. * Lots of water. I would drill 10 seconds, spray tons of water, then drill another 10 seconds and so on. * Drill lots of pilot holes. If you get stuck just drill a bunch more little holes and break out some of the pieces stuck in there. * Don't let brick build up inside the core bit. Always shake it out or pound it out before you collect too much which can cause the bit to get stuck. $300-$350 worth of equipment to drill holes is a bargain compared to what I was quoted. Have fun!
