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 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.

Thin material

If you need to drill through material (e.g. sheets) that is 1/4 of the drill diameter of thinner; check the various tricks on YouTube first (https://www.giangrandi.org/mechanics/sheetmetaldrill/sheetmetaldrill.shtml).

And generally - using one of the step/getrapte boren works better.

One box in the wood shop; one in the metal shop.
