CAT40 Tool Holder Collet Chucks for CNC Milling Machine

CAT tools were developed by an American company Caterpillar® and are used in CNC machinery.
CAT tapered tool holders are similar to BT tapered tool holders. The difference between CAT and BT is the flange style, thickness, and the thread for the pull stud is a different size.
CAT tools are also known as Caterpillar “V-flange”. CAT tool holders are designed as flexible devices that will accommodate different tools within a certain range of sizes. They will accept both imperial and metric sized tools. They consist of a taper (shank) and a holding head (flange). The Morse taper (male part) fits in the spindle’s female coupling, providing precise positioning of the tool and ability to switch it quickly.

We offer all kinds of CAT40 ER collet chuck (From ER16 to ER25, ER32, ER40 and ER50), here are the models and sizes in Inch:
