About two inches is pretty well accepted for the small boring heads, Perhaps the part No. 1 1/2 is a tip off to size.
Tom, on a Sherline lathe boring more than a 3" hole can be an adventure. At 3", the boring head can shake the mill right off the table! However, within those limits the S1-1/2 is very accurate and far superior to the Sherline offering. I have no regrets since owning it.
