<p align="center">Based on the ER20 architecture, our new 1/8" and 1/4" PC collet set brings spindle level precision and balance to consumer and commercial grade Porter-Cable routers. Reduced Total Indicated Runout (TIR), automatic collet extraction, more reliable tool retention, and improved balance allow Porter-Cable routers to be used with carbide microtools as small as 0.0156" dia. In other words, you can finally use a Porter-Cable to cut precision inlay for musical instruments, pool cues, and fine furniture.</p>

<p align="center">Two grades of collets are available. PG (Precision Grade) collets have TIR < 0.0004". UP (Ultra-Precision grade) collets have TIR < 0.0002". This compares to measured <b>TIR > 0.005" with original Porter-Cable collets</b>. Oh, by the way. Our new 1/8" collets means that you can throw away that 3rd party collet adapter <i>(that never worked anyway. OOOOOPPS! Did I say that out loud?)</i>. The 1/4" collet reduces tip wobble, allowing you to use your existing deep-reach router bits for deep 3D carving and profiling.</p>

<p align="center">All PC nuts have TIR < 0.0004" and are balanced to G2.5 at 24,000 RPM. Better balance and reduced runout translate to cleaner cuts, longer bit life and less wear and tear on the router bearings.</p>

Very nice. I posted a link to these last week, but noone replied to it. I'll be buying two of these in the future, for sure.

I'll let you know how it goes Ger, I'll be seeing mine in a few days. I'll be posted an extended review soon.

Received mine today and very happy with them.

Very nice quality.

Thank you for the kind words. If you need help inserting the collet into the eccentric snap ring, give me a call @ 719-488-9640 or SKYPE me at "thinkntink".

I am working on a page for the website showing how to insert the collet in the nut and how to remove it.

Do they snap in like ER collets?

Hi Ron

I already called you today, I was the one that said I know nothing about collets. Thanks for the help.

Gerry I'm not sure about other collets, this one click into place after you insert it in the nut at an angle and turn and it clicks into place. Comes out the same way.

george

Sounds the same.

Yup. Click the collet in, twist it out. Just like ER series collets.

tutorial page is finally loaded

Go to:

Let me know if it is at least passably understandable. Any comments would be most appreciated.

Im ready to order a set of them. Anyone else have some experience with them yet.

Got mine in the mail today. If the packaging is any indication, they'll be outstanding.

ger21 is right...they are outstanding.

I just finished a fancy "D" from the Vector Art collection for my daughter in .25 corian using a 1/8 v bit. It cut great.

I had been looking for a spindle for 1/8 bits, but with this nut/collet on the porter cable, I can stop looking.

IMO if someone was looking at routers for the spindle on their cnc machine, this nut/collet set would be the reason to go for a Porter Cable.

I got my set and I'm going to do a whole review this weekend. So far I've lightly placed my porter cable in my Bridgeport vice, I just used a very light finger pressure to close the vice as to not distort the router body. I measured the runout on the inside of the porter cable, the part the collet goes into. I measured at 4 different spots going from near the rim I got .00105", .00095, .000925 and .00095. Oh, and this Porter Cable is fairly new with very little use. I then chucked up, or should I say Up Chucked?, an 1/8" bit from Precision Bits a.k.a. Think and Tinker, and measured the runout on the shaft of the actual bit, I did this with a few different bits, and all bits were new. I got a range from .001025 - .000875. When I got these collets John at Think and Tinker said they got results better that what they had measured on the inside of the porter cable I too got better than that too. They are very well made and come packed with their special lubrication spindle sauce and you can see where they actually balanced the collet nut for low vibration. I would definately recommend these. I will do a further review on Monday when I take my Bosch out of my CNC and test it's runout after having it about 4 months or so. I did an initial review of my bosch when I firt got it but now it's had time to break in so we'll see how it's held up.

Yep Ive been waiting for this too. I didnt want to use adapters because of what I had heard of runout issues.

Sounds good so far. Ill probably go ahead and order a set this weekend because I would really like the 1/8th inch collet.

I'm going to start a new thread in the DIY CNC section because I don't think most people will look here, I wouldn't have thought to.

Ron,

It is nice to see you here. I have a few of the original PC collets that you offered some years ago. I always lamented you having to take those off the market.

I will certainly buy some of these.

Hi James,

It is good to hear from you again. It is interesting that you mention our last foray into precision collets (5 or 6 years ago?) This time I spent almost a week at the factory with our designer. Together we hammered out a complete QC sampling and qualification process and set up testing protocols to insure that the precision we need is maintained. So far so good. In any case, these little beasties make my PC 7518 run smoother than it ever has. Still too noisy for my taste but the cut quality compares to our Colombo.

Is the COREL plug in (Dragon CNC) fairly straightforward to use?

Hope everyone is doing well with new collets. Here is the video we made showing the comparison with an 1/4" OEM collet on our PC 7518 and the new 1/4" collet. Enjoy.

any possible way someday that you'll have a canadian distributor ???

In the past we tried the using the US Post Office, which was quite a bit cheaper. After years of fighting over lost packages and refused insurance payments, we gave up on them and went over to carriers with actual package tracking capability.

Hi Ron,

Well, as you know I have been working On CorelDRAW based stuff for some time now. I hope it is really easy to use, but that is a judgement that my users (beta testers currently) must make. If you get the time, join the beta program and help me give it life. I have designed in some inlay specific features including a selective corner overcut and the ability to specify a pocket oversize amount. Some of the latest stuff is not posted on my website yet, but if you are interested I can promise you world class support, just like when you patiently answered all my questions so very long ago.

BTW, my first set of 1/8" and 1/4" collets, nut and colletcare should arrive tomorrow. You have saved my routers from drastic modifications again!!
