Erickson™ BT V-Flange Shank Tooling System BT30 Series

Erickson V-Flange BT Taper Tooling is manufactured from premium materials and meets or exceeds the latest

JIS B 6339 specification and ISO-1947 taper accuracy of AT3 specification standards. The BT30 tools are either

prebalanced to a high specification or balanced-by-design and will perform effectively up to 18,000 RPM.

For any applications higher than 18,000 RPM, WIDIA™ recommends that the complete toolholder assembly

(toolholder, retention knobs, collets, hardware, and cutting tools) be balanced as one identity.
