3" bits

[rmock]

Will a 3" bit work in the machine?

rmock: Sorry, thought I was responding and was editing. I need to slow down. Post again please.

I know the software will not expect a bit that long. Might it break the bit or jam into something?

[rmock]

I didn't know if I could fit it up into the collet far enough, O guess I could cut a doll rod and see. Just wondered if anyone had used one

The CW deep bits are 3.5" long. What software do you have and what type of bit are you thinking about?

[rmock]

ok, I just want to try these as a regular 1/16th ballnose I do not want the bit to stick below the collet any further than the normal bit. Therefore I was wondering if the carvetight hade enough room for the 3 inch bit to slide up that far. or if anyone had tried these bits before

No problem. There is lots of room for bits like that. Are you going to press on a CT adapter?

[rmock]

I have just been using the standard pressure collet but I do have a er11 collet I thought I would use for this.

[bergerud]

I would go with the ER11 adapter. I use them all the time for just that purpose. I think the split adapter with a carbide shank is a bit risky.

[rmock]

thanks for the input, I will get a couple of these and see how they work out

I picked up a couple of bits and have been trying them out this weekend. No problems at all with the ER11. What were your thoughts on them?

I may be imagining this but to me they don't seem as sharp as some of my other bits. Could be the one I'm using only since I haven't tried the second bit yet.

[bergerud]

I think you are right. The bits with the coatings do not initially feel as sharp as the bare carbide bits. The theory is that they stay sharper longer but I do not know if that is true. The coatings may reduce heat and chip friction. For wood, I wonder if it really matters that much.

[oscarl48]

Dan, thanks. Good. That means as the coating wears off the bit will get sharper. :D

anti-entropy!

Just wanted to follow up I have been using these yonico bits for awhile now and they seem to hold up and carve very well $24.95 and free shipping

I'm going to try these! Are you using any particular 1/4 - 1/2 insert? Also, do you have to use the little clear plastic spacer anytime you use an insert?

[rmock]

we use the carvewright collet, I put a tape ring on the bit so I keep my length standard
