Smooth Cuts and Cutting Tools

I believe that is called a "shear" tool, something I have not yet tried but am looking forward to soon.
As Steve said, it removes very little material but produces a good finish.

With that shear bit info I dound it is old news on here, as should be because it is nothing new,

Glad to help! Seriously you can get a decent finish with that AR tool but it needs to be sharpened or replaced. I used a import that I dressed to do the rough cut on the sample stock. 570 rpm and .0055 feed. Pretty slow but I'm mostly too lazy to change speeds much unless I really need to. *note* that is not correct and one should change speed/feed/DOC to match the tool.

Steve,

Thanks for the pics and further explanation. You learn something new everyday here at THM. Every tool I have used and seen used the forward top of the tool was the first point to come in contact with the part. I will definitely grind one of these tools and give it a try. Another advantage I can see is that the tool will find it's own center of the work, no need to set center, within reason.

Jack.

About the center, there really isn't one as you can use the whole edge so it can be a long time before touch ups. I usually avoid the bottom and save it for when I need to get close to a shoulder.
