I think that is a hammer drill setting. Looks like a cordless dewalt. It will get into breeze blocks easily but 20 cm deep may be a challenge. You need SDS pneumatic for proper concrete. Not for breeze blocks or bricks. Depends on diameter too. If you need a hole for a dryer vent, you need a drill with decent power. Wall plug in breeze blocks, any drill will do
I need a 20mm hole to feed a CCTV cable through that has an RJ45 connector so it's a lot fatter than just a cable. I'd try work up in hole size until I get the right size. But maybe a cheap SDS is the right way to go.
Working up in size doesn't work all that well in my experience for masonry bits. They don't cut material, they pulverize it. Trying to run a larger bit through an existing hole is prone to jamming.
Can you get more connectors and a crimper and put on a new connector after running the cable through a smaller hole? That's better for sealing anyway.
Thanks. It's a weird cable with 3 ends: RJ45, power barrel connector and reset switch. The RJ45 is the biggest, but the others aren't too much smaller. I thought about having a junction box on the outside, but I'd like to keep it clean and tidy without.
