A beginners' guide to Home Metalworking

摘要

As well as working in engineering, David Clark has set up and operated several home workshops. This regular series offers much sage advice for the beginner. Another useful tool in the milling machine, is an engraving cutter (photos 25 and 26), these are readily available on eBay. You can get these in quite small sizes such as 3mm shanks and they are often made in tungsten carbide for long life. These engraving cutters are very useful as an alternative to the centre drill especially when a centre is required to be drilled on an angle. I have used these engraving cutters in production where they were very effective in centring holes at a 30 degree angle.
