Has Anyone Tried These Downcut Dremel Bits?

Hello everyone.

I came across these bits:

http://www.smallwonder-music.co.uk/shop/To...Bits/p-123-454/

Any ideas on how they'd compare to the Stewmac bits? They're a bit cheaper and located in the UK (which is good for me as I save on shipping) and seem to be essentially the same thing.

The Stewmac ones are 'reverse spiral' bits. Does that make any difference?

Also, what size would you recommend? My plan is to route close to the outline but then finish it off with chisels/razor blades to ensure a good fit. I was thinking of getting the T35 - 1.6mm (1/16").

Thanks for the help!

For inlays you probably want upcutting bits to remove the wood as you cut?

Also if you want cheap down cut bits look for a metalworking store and order a milling bit in the same size. Same thing only 1/3rd the price.

Do you mean something like this, but in a different size?

I'm a little confused now... I thought a downcut bit would be preferable for inlay because you're seeking to create perfect crisp lines to fit the inlay piece. An upcut bit would leave slightly less crisp lines due to the cutting action, no? Also, couldn't you just use a vacuum system attached to the dremel router base to get the chips/dust out of the way while using a downcut bit?

Correct on the bits. You can use any bit down or up doesn't matter. I have not found much of a difference if the bit is sharp. Buy what's cheapest.
