Background Information:

The SK system utilizes a proven 'fast taper' (7:24) self-releasing format. These conform to DIN ISO 7388-1 (formerly DIN 69871). Note that ISO, CAT, BT, and SK are NOT interchangeable even though they use the same basic taper!.

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.

Company History:

The company is a result of the merging of Metallwerk Plansee GmbH (Austria, 1921, later 'Plansee Tizit') and CERAMETAL (Luxembourg, 1931). The name Ceratizit was created by combining their names in 2002. Both founding companies originally produced molybdenum wire and tungsten lightbulb filaments, and were pioneers in commercial cemented tungsten carbide (since as early as 1929!) and their metal working / cutting tool product lines currently add up to over 80,000 items!
