Robert Tull-ABC Bird Toys Inc. They truly are state of the art bits. But I'm shure the sales staff at Skarie told you that. We were told, that if they were manufactured in the US, these bits would cost upwards of $80.00 or so. Oh, by the way, I posted that we usually cut about 3,000 parts before we change to new. Please keep in mind that our parts are not very big(about 4" in diameter). Just thought you should know.
Robert, you have given us a hang of a lot of useful information! Cutting speed, depth of cut, types of material, life, supplier, price, manufacturer, phone numbers, etc., etc.
(Don't get nervous now that somebody will come back to you and argue that they did not get 3,000 parts per bit!)
If there is a prize going for the most information, gained from personal experience, shared into the shortest space, then I would like to nominate Robert Tull! (Nomination may be withdrawn if Belin bits are a dud - LOL)
For everyone looking for that great bit I believe you wiil get the same results by using an Onsurd 63-725. This a .25" carbide single flute spiral. What makes it cut plastic, MDF, metal and almost everything so well is the small spirals that are behind the cutting bit. I have personally cut MDF at .5" deep at a feedrate of 2.4 inches a second with a 3.25 hp Perske. The noise level is 1/10th of other bits. It cuts Arcylic at 1.5" sec and leaves a polished edge (provided you use a climbing cut). You can purchase the bits from Hartlauer Bits. I think thier number is 1-800-644-bits
Robert Tull-ABC Bird Toys Inc. The onsrud bits you mention above are excellent bits. In fact, there are very few differences between the onsrud spiral o and the belin spiral o. We have tried both the onsrud spiral o and the belin spiral o. without much difference. We do prefer the belin because of the high polish on the bit. It seems to eject more chips(slight amount) than the onsrud. I do agree with David Ford though. Try the Onsrud; you may like it better than than the Belin spiral o. Also I think it's important to mention that we only mill wood; pine and poplar. So our experience is strictly based upon this material.
I just checked the catalog and noticed that both Onsrud and Belin have upcut and downcut bits. I gather from other messages I've read here that the upcut bits would be better when using the dust skirt.
(I just ordered my ShopBot last Friday (2/23) and I'm getting prepared for delivery in about a month.)
Upcuts clear better for sure, but you should also consider how you want the finished edge to turn out.
I use an upcut in one process where I'm doing a long a deep vein in hard maple. I'm not too conserned about the condition of the top edge of the cut.
I do pocketing in other areas in quilted maple where an upcut or a straight bit would be blowing chunks of wood off the edge continually. Here a downcut spiral bit leaves a nice clean edge with nothing to clean up.
If you are more worried about the bottom of your work, then the opposite applies. If you are cutting sheet stock, then a compression spiral might be in order.
Question for the group: I wonder how using a compression spiral in blind pocket would work. Hog primarily with the upcut tip then finish cut at full depth so that the pocket edge is being cut with the downcut portion.
Robert Tull- ABC Bird Toys Inc.- Check this news out about bits. It may be hepfull to shopbotters.

I called the Belin rep. in my area and he sent me a sample of the Belin "spiral o " bit. Also he told me that REECE SUPPLY in Norcross,GA has them on the shelf. They have Part No. 13635 (1/4 dia.
x 5/8 cut length) for list price of $28.35 (Discount price available). They also have Part No. 13635A (1/4 dia. x 1 1/2 cut length for $36.50
(Again discount available).
Reese Supply's phone number is (770)326-7920 and
ask for Russell Moss.
The bit has a deep single flute with several
shallow spirals behind the flute an is highly
polished. Just received it haven't tried it yet
I will report on it as soon as I try it.
Also PriceCutters.com on the web has $9.99 upcut
spiral bits in their special deals area (3 to an order). Hope this helps.

Hi Guys,
The companies listed here are some that Dave came up with. I hope it helps!
CNC Router Bit Supplier Information
Many companies manufacture router bits suitable for CNC use, and a few are listed below (this list is not exhaustive). For any given application the suitability, longevity, and price of bits from different manufacturers can vary greatly. Bit manufacturers can offer advice on selecting bits and feed rates suitable for your specific application. Bits with unusual diameters and/or cutting lengths and bits designed for specific applications may only be available from certain suppliers (so it helps to have several bit catalogs on hand when searching for the bit you want). Keep in mind that not all manufacturers sell direct, so you may need to call the manufacturer to get the name of a distributor near you. Local distributors listed below serve the North Carolina area.
To produce your part with the lowest possible cost-per-part, identify the appropriate bit size for your application, then experiment with different bit types, different suppliers, and different feed rates. The right combination for your application can increase the usable life of your router bits while improving the speed and quality of your cuts.
