Just putting a feeler out here. I do a lot of CNC work that requires deep, clean cuts on solid wood right off the machine. Since it’s a very demanding task, router bits are replaced as soon as any hint of chipping or burning shows on the wood.

The bits in question are single flute, Vortex 830 1/4” diameter, 1/4” shank upcut spirals with 7/8” cutting length. They still have plenty of life for use in hand-held routers but would have to be re-sharpened for CNC use.

I’m undecided if I should offer then for sale at $5 each ($31 is the cost of new bits) or resharpen them and compensate for the decreased cutting diameter. Anyone here have a use for these? The other day I chucked on into a laminate trimmer to do some inlay work and it cut 1/8” deep passes with little effort.

JAAune, I also use a lot of cutters and buy in bulk from Toologik http://toologik.com/
You should check them out. The price will surprise you. Tom

I’d be interested in some. 1/2 Shank? What size is the cutting diameter?

I would also be interested. Let us know what you decide.

Thanks but for my application Vortex and Onsrud have the best feedback from CNC guys at WoodWeb. The bits need to be fully optimized for CNC routing solid wood otherwise the parts need a cleanup pass. I don’t actually pay $31 myself per bit because I buy in bulk too straight from the manufacturer. If you’ve got $350 to burn, Vortex gives good discounts.

I thought I put the diameter down but apparently forgot that. At the moment, I’m using 1/4” diameter, 1/4” shank bits in bulk so those are the only ones I’d be selling. I’ve updated the original post with the appropriate information.

This week I’ll send a small batch to Vortex for re-sharpening so I can make a final decision. Another CNC guy is telling me 1/4” resharpened bits don’t hold up as well as new ones (which combined with size change would make them too much of a hassle) but he’s using 2-flutes so I need to check a re-sharpened single flute before making a definite decision.

Carp foreman uses vortex strictly for the CNC machines. Amana for handheld.

They bought a bit for doing 6” thick styrofoam. Guess the price on that bit? $500!

Custom made. It was 10” long.

I didn’t realize they are made in U.S.A. Cool. Will have to check em out.

I get our 1/4” bits sharpened 2-3 times, and don’t see a lot of difference. We use cutter comp for everything, so the programs don’t need to change at all.
I started using 3/8” bits when cutting hardwoods, though, as they last a LOT longer than 1/4” bits do.

In my case, the CNC machine is under-powered so 3/8” bits would just bog down and I need to nest as tight as possible anyway.

In this case, under-powered means my spindle doesn’t have sufficient power to do the work I need to do. I’m compensating by using small diameter, single flute bits. I’m not doing anything weird like reducing the voltage to the motors.

As an update to this thread, I had some bits resharpened but haven’t tested them yet. So I’m still not ready to make the decision between keeping or letting go of the bits. I did find out that they can only be resharpened once.

Just tested the first resharpened bit. It held up as long as a new one so I’m going to reuse rather than sell the bits.
