inserts

I am wondering if anyone knows what these inserts mean, I have the 3/8" shank size, so it says IC size is 1/4".
But what is the 221 and 222 mean? I
was going to get a few while ENCO has the sale.

The first digit is the insert size in 8ths. So 2/8ths or 1/4" The second digit is thickness in 16ths. 2/16ths = 1/8". The final digit is tip radius in 64ths.

221 is 1/4"-IC, 1/8" thick, 1/64" radius
222 is the same IC and thickness with a 1/32" radius.

The codes are in your Enco catalog at the beginning of the insert section

Jetdoc is a faster typist than I am, I see.

Before buying any bars with inserts, check the price of replacement inserts. Some get pricey when bought after the initial purchase of the bar and inserts.

I've had this bookmarked forever, as it really helps buying inserts on eBay, because some times they are listed using the ANSI format, and some times ISO.

I have two sets now, one will be dedicated to steel, and the other to aluminum.
