High HP ruffing with a PM-940 size CNC mill 

For the tool holder they are 25mm shanks. That does not fit the largest R-8 collet of 7/8" so you have to cut to length and then turn them down to 7/8". The holders come at 150mm or 200mm most the time for the shortest length. They are slightly hard. The inserts are for aluminum only, They are"ground" APKT1604PDFR-MA3 Or APKT1604 HO1 The holders can be found for under $20 most the time. I search for 1604 holders and then sort by price. The clone inserts are way better than I thought, they last a long time. If you don't have a lathe to turn down the shafts you need to do the 20mm holders but they don't work as well and take the smaller APG1135 HO1 OR G2 Insert. For the 1135 you might have to releave the pockets slightly because of the lip in the ground inserts.

Nice to see you around Bob. Might be doing a road trip your way in the spring.

@@ArizonaVideo99 if you have the time stop by. You can criticize how nasty disorganized and cluttered my shop is. If you have a little more time and you're into it we can take the boat out on the river for a little while and chase some green slimy fishies. You've got my address. Drop me an email if you have the inkling.

Yep. I'm going to do a new drive for my second IH which is coming up soon. I also need to do one for my PM-940 so I will do them at the same time. I will make a few extra ones, a number of guys have asked over over years for them. Keep an eye out and I will post them.
