Product Features:

- DIN ISO 7388-1 SK40 · Weldon Basic Line

- short

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 Weldon interface utilizes a straight bore and one or more setscrews to grip the tool shank, and was invented circa 1918 by Carl A. Bergstrom in Cleveland, USA. Although seemingly crude and archaic, this style of tool holder interface often outperforms more modern systems when it comes to extremely heavy machining loads, and cannot be beat for simplicity.

Company History:

Family-owned since 1977, HAIMER has grown from a precision parts specialist into a global tooling solutions supplier with operations across Europe, North America, and Asia.
