Tips on Drilling

1. Clean hole

- Blow the hole frequently when drilling deep

- Soft or muddy ground can seep causing the steel to hang up

- Blow with every drill rod added below the hole, preventing a plugged steel

 

2. Drill dieseling

- Occurs with insufficient feed pressure

- Also happens with full throttle when withdrawing the bit

- Dieseling heats up the drill and burns off the lubricant

- Results could include a destroyed hammer

- Stop dieseling by reducing the drill throttle and increasing feed pressure

 

3. Changing bits

- Try to follow a larger bit with a smaller bit

- Try to use new bits with new steel

- Use lubricant on bits, as well as couplings and steel threads

- Remove bits with a bit wrench or “rattle” loose, no beating with a hammer
