Background Information:

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 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.
