RobbJack Features A1-303 Series at the 2017 Design and Manufacturing Show

January 9th, 2017

For Immediate Release

(Lincoln, CA) – RobbJack Corporation will showcase the A1-303 series carbide end mill that allows you to machine deeper parts, slots and walls in a single pass with minimal chatter and vibration. This tool is excellent for high speed machining. This series comes with polished flutes and Mirror Edge to eliminate chatter and vibration in high speed machining of aluminum and non-ferrous materials. The shank tolerance is the best in the industry (H4 tolerance on all sizes larger than 5/16″, and H5 on end mills smaller than 5/16″), which eliminates tools pulling out of tool holders. The RobbJack 1” end mill also has the ability to remove 42 pounds of aluminum every minute.

To learn more, visit RobbJack at Booth 3414 at the Design & Manufacturing show in Anaheim, CA Feb. 7-9th, 2017. See the video of this tool in action!
