Carbide/Carbide Tipped Reamer Speeds and Feeds:
Below is a table showing our Recommended Starting Speed and Feed Parameters we recommend running our Carbide Reamers and Carbide Tipped Reamers at.
You want to leave 2%-3% of the hole diameter for the reamer (Example: .1250" Reamer needs to be drilled to .121"-.1225" Diameter before Reaming).
