BT15 ER Collet Chuck Tool Holder

The BT15 ER collet chuck is suitable for use with a CNC milling machine center and has a gauge length of 35 mm. The BT15 ER collet chuck is designed to work with SE16 series collets, which are self-centering collets. The SE16 series includes collets for different shank diameters, such as 2 mm, 2.5 mm, 3 mm, 1/8 in, and 4 mm.

ER collet chucks, also known as Easy-Release collet chucks, are a popular tooling system that holds cylindrical shank tools in ER collets. When a tool is inserted into a collet, the device expands and applies uniform pressure to hold the tool in place. This allows the tool to be held in a central position while it rotates.
