I need to drill a107mm hole through brick to fit an exhaust fan. My drill is NOT SDS. I am not sure if it has a clutch. It is a corded one with 680W (bosch psb 680 re). Is it safe to use it for core drilling? I got the following bit and arbour - Erbauer Diamond Core Drill Bit 107mm. The first layer is tile. I have drilled a pilot hole and planing to use it to keep the cut straight
1) Is the drill powerful enough for the cut?
2) Is the drill safe for the cut (it might not have a clutch)
3) What speed should I use, fast or slow?
