Newbie- Soft to Hard Metals what bits to use for Cutting Carving Engraving

[guy2b1]

Im planning to cut, engrave or carve different kinds of soft to hard steel or metals such as aluminum, copper block, PC casing, etc.

- what bits should I use for engraving carving and cutting?
- what reminders should I consider for safety operations?
- what are things needed for cutting engraving metals to prevent heat and blunting my cutting engraving tool bits?
- any tips and tricks? any picture to share about the actual tool bits?

Im using a 35,000 rpm 500watts power tool as my spindle not variable speed. I have done some wood working projects and planning to learn and experience about steels and metal cutting and engraving please help

i mainly use no. 1 ,2, an 3 center drills for engraving 1/8 in. thick alum. it works great . i run about 30 in. per min. that way its very fast. an clean .no. 1 for fine line .up to no. 3 centerdrills for thicker lines . with very little tool wear . try it .it works good.
