We have two - one in the wood shop and 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.
