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.
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 Stappen boor / Getrapte boor / Step drill works better; or the Grote Gaten Zaag - Large Hole Saw for bigger holes.
Location
One box in the wood shop; one in the metal shop. Both near the drill press, the Drill press wood and the Drill press metal.
