Step 33. When you feel the drill bit has cut into the material ( one edge of the hole is about to form), slowly stand the drill bit upwards to 90°.
Step 44. Keep drilling vertically until the hole has been completely formed. Can shake slightly to help remove chips and dissipate heat. Dont greatly sway. The kit contains the hex adapterYou can use these tile bits on your hand drill with the hex adapter.

Recommended RPMMake sure the speed is higher than 2000 RPM
. Typical hand drills are 2000-5000 RPM. Within this range, the faster the drill speed, the longer it will last. So we don't recommend for a cordless drill. The lithium drill has a lower RPM, about 1000 RPM. Function instruction1. Drilling holesWith different sizes diamond core drill bits (6/6/8/19/25/35/50/75/102mm).
