Dremel cutters

Postby Mike G » 06 Dec 2017, 11:33

Morning all.

Does anyone here have a Dremmel? If so, I want to pick your brains about cutters. I want to do some really fine engraving in timber, and in brass. I'm talking about say between 1/2mm to 1mm width of cut. What do I need to know about cutters? Are they all the same, or are there separate ones for each material? Thinking about it, I guess I would want a "V" shaped cutter for brass, and both a "V" shape and a straight cutter for wood. The latter is in case I want to inlay.

Are there any decent starter kits of cutters that you'd recommend? How long do these things last? And on the machine itself, are there any non-Dremmel brands worth considering?

I have a Dremmel but they are a little slow you could try http://www.woodart-products.co.uk/3_rot ... dpiece.php

As I already have a Dremmel I bought a selection of collets that allow me to use other brands of bits there are loads out there I tend to buy mine at shows when I see them, but Woodard above are good for bits

I’ve got a Proxxon that came with an assortment of cutters

I bought this as a starter set. It's seems to do the job o.k but I've never worked them hard. I also bought the genuine dremel set of router cutters for around 26ish quid. Haven't tried them yet, but they look a bit rough and ready. Knowing what I know now I wouldn't have bought the dremel set. I'd have bought cheapy Chinese cutters that no doubt would have looked equally as rough.

What are those for cutting, Coley? Wood only? How would they do with brass, do you think?

Mike

Do you have your Dremel yet ? I have one that you are welcome to try on long term loan. Personally I prefer the Proxon. I've tried all sorts of cutters. None of them last very long.

I've used them on hardwood and the odd bit of metal.... i think. I'm just trying to think if I've got any brass I could try it on. I'll have a look after dinner- I'll try a less useful one on some metal and post a few pics. I think that set came from Axminster. I've put the dremel set somewhere safe where they won't get lost ! lol

Works quite well on brass

Prefers a slower speed instead of flat out.

I haven't Bob, no. That's very kind of you. As it happens I am wanting to build it into a device/ machine/ invention, and it may need some permanent alteration to suit.....so I'd better not borrow it. But many thanks for the offer.

Thanks for doing that. So they don't need to be diamond tipped.

Not sure why the other pics didn't work

It covered my apron

This seems to work, perhaps a diamond would be even better perhaps ?

After an much searching I have just found my dremel. Hasn’t had much usage here, it still has a 3 pin plug attached.

Anyway is this any help.

Note the comments about a steady hand in wood, that was my experience, very difficult to keep in a straight line. Mounting in a jig would help, or pehaps their router attachment. Never used on brass.
I do not think therefore I do not am.

If you are going to buy, Proxxons get the better write-ups.

Mike,

If you are mounting the device in some sort of machine/jig etc make sure that the endfloat is minimal.

This usually means the tool needs a ballrace bearing not a plain bronze bush.

Without good control over endfloat the resulting engraving will likely have a poor finish.

Try before you buy would be my advice

I spent quite a bit of money trying to turn the dremel into a small router. I wish I'd bought the little katsu router before going down that route !! The most useful application I use the dremel for, is cutting with the small discs. I think they're fantastic, they've got me out of a hole many times.
I wonder if the little katsu with a reducing bush might be another option Mike ?

Ah, a little trimming router. Yes, the machine will take two routers......a small trimming router like the Katsu (other brands available :) ), and a Dremmel. The Dremel/ Proxxon will only be for the finest smallest work.

End float is the amount by which a shaft can move lengthwise.

Thanks. The design principle of the whole set-up is to eliminate unwanted movement in X, Y & Z axes.
