I picked up a handful of small surplus Osrud cutters of various sizes and flutes with wax still on them. They were cheap (~$2.50/ea).

I'm trying to look them up but the numbers on them don't seem to be in Onsrud's site. A couple of the numbers are like: RBL-22015 and RBT-21494.

Any ideas how to find out more info about them? Do I have junk or treasures?

I think they might have changed the way they numbered their tooling. If you can post pics I might be able to identify/cross reference them...

I suspect they are all woodworking bits. The notes have the text that is printed on the side of each cutter in the order it is printed. I threw in the Vortex cutter since I couldn't find any information on it either.

Thanks for the help.

Are you sure that's a Vortex bit? I've been using them for 15 years, and have never seen one like that. Also, there numbering system hasn't changed in that time.

I can't vouch for the validity of what is printed on the side of the bit, but that's what's there.

The first looks to be a straight O-flute, used mainly for plastics. The two spiral-Os could be used for either plastics or wood. Don't know much about the last but looks like a downcut spiral. My best guess, if you got them from the same place, they were used for plastics machining.

The Tubelite PDF document at http://www.tubelite.com/docs/electric/TubeltCat_Equipment_pages414-480.pdf

Page 446 shows the 220000 series made by LMT-Belin as "Belin 22000 series - downcut Single Flute Spiral ‘O’" and it's for Aluminum, Brass, Copper, Non-Ferrous Metal.

This is the only related Google reference I found. It's a 3mm shank, 1.5mm cutting diameter, 4mm cutting length, 30mm overall length carbide cutter.

LMT-Belin, LMT-Onsrud appears to be divisions of the same parent corporation.

It appears they were both acquired or merged with LMT (Leitz) between 1999-2001. Prior to that they were not affiliated at all.
Belin is a French company. I've heard they make excellent tooling, but have never seen any.

Wow, that's the one. I'm impressed that you found this. I'd like to know how you did it.

Maybe I should go back and buy the rest of these. They were only $2.50/ea.

I purchased #3 Craftsman Professional Carbide tipped 3/4in. X 90° 1/2 in. shank V Grooving Router bits for $18 and change shipped that is less than $6.00 each. They sell for $27.99 each at Sears I don't know how good they are but I will soon find out and yes there are more at that price E Bay..

Just got a pack of 1/8" Kyocera Tycom endmills from Drillman1 on Ebay, they look and feel much sharper than any of the chinese endmills I have. I have a lot of faith on these for aluminum work, which is what I got them for.

With the cost of high quality endmills so low, it doesn't make much sense to me to buy Chinese bits, of whose quality is suspect.

I will say that these 1/8" Kyocera bits work very well in aluminum, as well as other materials.

I have a piece of aluminum 17"X 28"X 1/2" I want to start on that next year lets see what I order from Drillman ..

Very good information,just what i needed:: winery

Thank you for this thread. I'm waiting my CNC to be delivered and I'm finding out the more I learn the less I know.

I have a kind of related question as a get ready to buy bits: my machine has an er 20 spindle and I' m waiting to hear back from the salesman what size collets it has but should I buy full sets of metric and English collets for it or are there really just a few sizes I would need?

Welcome! As to collet sizes, it's probably best to buy collets as you need them. For wood (and probably most metal work you may do) you could get 1/8", 1/4", and 1/2" to start; they're probably the most commom standard sizes. Many performance router bits come in 3/8" so that may be a size worth getting, especially if you will cut a lot of sheet goods.

Similarly, it's probably best to buy tooling as you need them as well. It may be tempting to buy a "mega set" at a discount, but you may find you don't use about 2/3 of the bits in the set. Once you establish what bits you use the most, you can keep multiples of each to minimize downtime in the event of breakage or wear.

[ger21]

As Louie said, 1/8. 1/4, 3/8, and 1/2" should be all you need if you're buying standard fractional size (not metric) bits.
An ER20 spindle should use ER20 collets.

Thanks louieatienza, that's kid of what I was thinking on the collets so glad to hear that recommendation.

As for the bits I learned that one a long time ago unless there is a specific set for something like the Leah jigs etc.
