This equipment is safety category 6: Other equipment with no limits.
This equipment is Noise Category 3: Can be used at all hours. No limits.
These are generic large size drills (sizes 14, 16, 17,18, 19, 20,22 and 25) for use in wood, plastic, metal, etc.
Consult a table with RPMs - as that really starts to matter at these sizes.
Also; unless you are dealing with very soft wood - expect to drill in steps of 1-3mm; going from small to large.
See [[Metal Drills] and Categorie:Boren for normal size drills.
