For best results we recommend the drilled hole be .012 min.- .032 max. under the size of the Pre-Ream Endmill.

Save time with Pre-Ream Endmills.

Dramatically increases the accuracy of reamed holes over traditional drill and ream operations. Eliminates the set up of a boring bar to qualify or skim bore

a hole to prepare it for accurate reaming. Extends the tool life and consistency of reamers. Allows reamers to cut the exact same size every time. Improves accuracy

of true position location by correcting any drill error that occurs in the drilling operation.

Great for Carvesmart Jaws and Dowel Pins in General
Lars (Erie, PA) 12/3/2019 5:22 AM
I use this all the time to make my Carvesmart jaws that need to 0.250” dowel pin for location. I also make LOTS of parts and assemblies for in-house machinery that need .250 dowel pins. I use this tool to “drill” and bore the holes or I follow this endmill up with a Lakeshore reamer. I keep this tool, the reamer and dowel pins in one drawer, it’s like the perfect go-to kit. So much for hunting down reground end mills at a similar cost.

Who ever heard of a pre-ream end mill? I never had, but now I own them in .119, .181 & .244. The fit tolerance on my dowel pins is ridiculous because of these end mills. I drill my pivot with a 15/64 Lakeshore carbide drill, pre-ream it with the .244 and ream it after heat treat with their carbide .2495 reamer. My AKS pivots fit like the wedding night. Highly recommended.
