I have used these bits (happily) from this supplier for quite a while. Always bought off eBay. The seller recently informed me I could by selected bits in sizes and quantities that I preferred. There are new and slightly used bits. I get the slightly used ones. Your choice.

Fish tail: http://drillbitsunlimited.com/Carbide-R ... 48900.aspx

I really like the fish tails for inlay work.

Thanks Mike, just what I've been looking for, ordered some up to try.
Do you used these on spruce tops?

The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

Yes! All the time. I've only used the lightly used ones. And they have lasted a long time. I recommend the fish tails for the kind of work we do. If your using one of those edge binding cutters that can use spiral down cut bits, I'd use those twin flutes. That's a guess on my part.

Mike,
Those look exactly like the bits that are used for circuit board milling.
I bought some random sizes from an electronic supply store. Thanks for the web link!

I think that is exactly what they are/were used for (according to their website). I would not recommend them had I not used them. You can also buy them new. Though, I'm not sure the added cost is justified. The lightly used ones are quite good

Thanks for the link. Just bought the 50 piece set . Looks like excellent value, and shipping costs to the UK very reasonable IMO.

Wow, thanks, Mike!
Just ordered 40 - .050" at $.89ea! Good for those single BWB rings on rosettes.

It's like being a kid in a candy store

bookmarked!

+1 Thanks for posting the links, Mike!

I really hope it works out for you all. I've never had an issue and love the bits.

How do these compare to Stewmac inlay bits?

I bought some small end mills for use in inlaying from a supplier in Taiwan, but they are nowhere near as sharp as the Stewmac bit. The Taiwan bit costs the same as the ones advertised on the link the OP provided, but not really sharp at all. The stewmac bit is extremely sharp and makes a very clean cut, especially in hard materials like ebony. However the Stewmac bit costs too much.

Great find. I ordered 10 of the .032" bit, which is what I use for cutting shell material on my CNC. I ordered the new ones -- they're more than the used, but they are 1/10th the price of what I pay at PreciseBits. We'll see how they hold up.

Well, now, I never made claims that these were on par with precise bits. Those guys specialize in the kind if bits that go beyond the norm. I'm using these on wood. Not shell. But do let us know how it works for u.
