Product Description

BT tooling is symmetrical about the spindle axis. This gives BT tooling greater stability and balance at high speeds. BT tool holders will accept both imperical and metric sized tools, BT tooling looks very similar and can easily be confused with CAT tooling. The difference between CAT and  BT is the flange style, thickness, and the thread for the pull stud is a difference size. BT tool holders use metric thread pull stud. We have G6.3 rpm **********0 and G2.5 rpm **********0.
