Hi, I have been using a very small hobby drill for the past year since I started making silver jewelery, but it hasnt enough power to drill holes, so I have been using a DIY drill which is heavy. Can you please advise me if its better to buy a better, bigger hobby drill/multi-tool ( I was looking at the Dremel 4000 with its add-ons and a Black and Decker one also) but although they say on the tin that you can use them for all jobs within reason, I have about £100 to spend and want to know if its better to get a smaller DIY drill now and a separate polisher at a later date or get the bigger hobby drill/multi-tool. The thickest silver I will be drilling is 2mm, but the little one I have now which is a Blackspur wont touch it, so I am a bit dubious about buying another one.
