REGO-FIX BT-B 50 / ER 40 x 160mm Projection, 0.0001" TIR, Balanced to 25,000 RPM (Form-B Coolant )
Rego-Fix is a leading tool holder brand based in Switzerland since 1950.
The BT system utilizes a proven 'fast taper' (7:24) self-releasing format and is common among non-European machine tools. Note that ISO, CAT, BT, and SK are NOT interchangeable even though they use the same basic taper!.
The BT-B modification adds flange/face contact for improved rigidity and accuracy and provides coolant-through-tool capabilities with a port drilled into the flange.
The ER tool holder system was invented by Fritz Weber, founder of Rego-Fix, and released in 1972. The ER-type system was originally used as a broom head to handle interface! The R in 'ER' stands for Rego-Fix, and represents the company's modification to common 'E' collet design of the early 20th century. Specifically, the modification was adding a groove to the collet which keeps it captive in the nut while installing/removing; eliminating the problem of collets getting stuck in the holders. Upon patent expiry the system was standardized in 1993 under DIN 6499 and is today the most recognizable and commonly used collet system worldwide.
The classic ER interface, tried and true.
