- Please start drilling slowly with an angle of 45 degrees to make a

mark for the drill bit. 

-After you have an initial mark, go vertical.

- Be patient and let the tool do the work it self - take your time.

- Cold water as a coolant is a good idea. You have have a small

pond around the hole with clay and fill it with water - crushes ice,

etc. Or you can have water flowing to cool.
