    That insert looks just like the ones for my Shars holder . The holder
is a Shars P3W x 3/4 , number on the container is 202-9578 . The insert
package is numbered 404-0416 , might be the Shars part number . They are
1/8 thick , .562 long and .311 wide at the widest point .

Thanks, the picture for 202-9578 shows the insert not bottomed in the slot, same as mine, so the inserts should be correct for the holder, they were in separate drawers of used tooling from auctions. The series is GTN which I can now look up. Google is like magic; you have to know the right words.
 Are there any special tricks to using them? With HSS I run below chatter speed and keep the bottom of the groove constantly oiled with a needle dropper bottle.
 

   No special tricks that I've found . I run them the same way you do HSS .
