Hi,

I’m trying to figure out how to machine some H7 fit holes with a conical clearance from the backside. The H7 holes are rather deep, and I want to make proposal for the customer with this conical hole from the backside, as if possible to drill/ream, will make the part a lot easier to make. It is for the food industry, so I can’t just drill a bigger hole with a drill, as it will be impossible to clean. And I need to make about 500 10H7 holes????

I have been searching the internet for conical pin reamers and drills, but I can’t find anything that is made for machining centers, and can be used to machine stainless steel.

Any help is appreciated☺️

Cheers,

Daniel Uhrenholt
