Reply To: Looking for an engine boring service

These types of cylinders are referred to in the trade as ‘blind holes’ and if your machine shop can’t bore it, I’d shop around and find a competent shop that can. A special holder is needed for the cutting bit on the boring bar and it sounds like your shop doesn’t have this attachment. This tool holder holds the cutting bit below the surface of the boring head so it will cut all the way down. Using a standard tool holder will leave a lip at the bottom of the cylinder. Maybe if you buy it for them, they will bore several motors for you for free!

Here’s a link to the type of tool holder they need:
