We have two - one in the wood shop and a heavier one one in the metal area.

Cutting wood in the metal area is fine. Cutting metal in the wood area is frowned upon. If you do so - de-grease the machine/plateau post use !

The drill press is classed as a normal, somewhat dangerous machine: instructions strongly advised but not mandatory. It can be used any hours -- but be kind to our neighbours.

Use of safety glasses will generally be needed. And the use of gloves is possible; but a mixed blessing. It increases the risk of your glove (and with it your finger) getting twisted around the drill/rotating head.

Its main risks are flying sharp bits, getting caught in something rotating or your workpiece rotating/spinning.

So clamp things well.

Changing speed

adjusting drill speed

Always use the right speed; you get a nice round hole, it goes faster and the drills stay sharp.

See https://www.youtube.com/watch?v=hbig6nOl398 for a video on changing the speed.

Speeds and oil (metal)

There is a chart of speeds on the wall -- or see http://engineering.ucdavis.edu/wp-content/uploads/2013/08/lathespeeds.pdf

The larger your drill diameter - the lower the speed (Alu faster than steel faster than stainlesssteel/rvs); but limit countersinks/counterbores/stepdrills and similar `specials' to 200-300RPM.

There are three types of oil next to the machine. For most metals use the green oil.

Use the non-ferro oil if you find that the green oil stains your aluminiun/non-ferro metal (this is quite rare).

The third oil is generally not suitable to use with this drill press.
