Feature：

■ When ordering, provide us with the manufacturer, model and specifications of the machine tool, as well as the BIG product model number.

■ Kindly inquire us regarding Stop Block and mounting dimensions.

■ Kindly check with the machine tool manufacturer for the shape of the Stop Block, as it will vary for each machine tool model.

■ The dimension from the spindle gauge line to the top of the Stop Block （※） is our standard length.

▲ As the Air Turbine requires clean air, do not share the same Stop Block with other products.
