how to drill a 30mm hole on a Tiles? what accessories do I need?

I dont owned any Makita stuff, but those cheap on Shopee are fake/clone. I bought Borsch and Hikoki (Hitachi) which is genuine.

I think the (1) are easy. As for (2), depend how deep or big you plan to do the work. For example I plan to DIY to drill 10mm hole into concrete brick to mount my TV (like more than 6 holes), I just bought myself Hikoki/Hitachi Hammer Drill (wired), the rest like painting/clock/accessories also quite easy to get it done. I think bought it for like RM350 because after survey mounting on the TV on the wall labor also cost like around RM150-200 iinm, so might as well I do it myself with the power tools I bought. You can find some other brand for cheaper hammer drill.

Since you no state budget, other sifu here hard to recommend based on your situation for DIY.
