Hosel bore

I have a set of 712 cb irons. I want to pull the stock s300 and I will be installing DG tour issue s400's. I wanted to know the hosel bore for the CB head so I could do my measurement for tipping and playing length. I play my current s300 at 1/2" over titleist standard length. Any help would be great. Thanks. 

Andrew, 

The hosel insertion depth for the 712 MB is 1.070" for the 3-7 iron and the 8-P is 1.270".  The tip diameter is .355 taper.

Is this the same for the CB's?
