I have a 8220 dremel with drill stand. I need to drill countersunk holes to house very small brass screws in wood. What is the best dremel accessory for this please.
Welcome to the Bunnings Workshop community @ronmcm and thanks for reaching out with your question.
It would be helpful to learn a bit more about your project so that members can offer the right suggestions. Could you let us know what you're building and what type of timber and screws you're using?
I think this will be close to what you need, outside of a kit.
Unfortunately a rotary tool is not a tool that I have in my collection, so I can't really comment from experience on counter sinking with one. I have done a bit of research and it seems that you can achieve a countersink effect by using a dremel drill bit and then using a conical shaped router bit.
Personally I would use a drill with a regular countersink bit to do the job, however if the screws you are looking to use are tiny it might not be feasible. In that case I would probably use a slightly larger drill bit to drill a space so the countersunk screw will sit flush with the wood.
Let us know more about the project and we'll try to provide more specific assistance.
Re: How to drill small countersunk hole with dremel?
Thank you for tagging me, @StevieB
I'm not sure what the collet size is for a Dremel tool, you could try this small countersink bit, to see if it fits your Dremel, I agree with @tom_builds
suggestion also, you might need to use an electric hand drill to do the countersink after you drill the item.
I think the shaft size on the P&N is too large, 3.15 is the standard for Dremel and you can get chucks that take up to 4mm.
I have the 12v Bosch look alike and the 18v 6mm die grinder in what was supposed to pass for a cheap milling machine even though Bosch say not to fix it into anything, it may also fit my CNC when it gets here.
Their suggestions are actually all going to work, however, you will have to get a compatible collet nut kit from Dremel. The kit number is Dremel Collet Nut Kit 4485 and has to be specially ordered at the store. If you need assistance ordering this item, please tell me the closest store in your area and I will give you a hand.
Removal and fitting of the kit is not complex and no special tool is needed for the exchange. If you are doing a D.I.Y. project we would love to see what you're currently working on.
If you need more information or advice, please let us know.
