Damaged tools may cause some imbalance that can be critical at high speeds and precise CNC machinery. We highly recommend your shop implements a regular preventive maintenance program to protect your investment in cutting tools, tool holders, and collets, and reduce scrap. (runout) which leads to the premature wear of the cutting tool, tool holder, and spindle mouth. It’s important to remember that all of these components are manufactured to perform within tolerances of ten thousandths (.0001”) of an inch.Īny dirt, dust, oil, chips, or other contaminant left on the spindle, taper, flange, collet, collet pocket, or nut can cause poor T.I.R. To ensure proper performance of your tool holders, the overall cleanliness of every tool holder, collet pocket, collet, and nut must be maintained. They are durable and the best choice for high-speed machinery.īT tools use ATC (Automatic Tool Change) technology to maximize the speed and productivity in manufacturing. That makes BT tool holders better balanced and more stable at higher speeds.Īlong with CAT and HSK standards, BT tool holders are among the most used in CNC machinery. Though both standards use the same NMTB body taper, BT tool holders are symmetrical around the main spinning axis while CAT tool holders are not. BT tool holders use metric thread pull studs (retention knobs). The difference between CAT and BT is the flange style, thickness, and size of the pull stud thread. BT tooling looks similar to and can be easily confused with CAT tooling, but they are not interchangeable. CAT Tool HoldersīT tool holders accept both Imperial and Metric-sized tools however, BT tools come in Metric sizes. This gives BT tooling greater stability and balance at high speeds. BT tooling uses the same NMTB body taper as CAT40 and is symmetrical around the spindle axis – something CAT tooling is not. The higher the number, the bigger the taper. Similar to CAT tool holders, they have numerical designations that correspond to the size of the taper: BT30, BT35, BT40, BT45, BT50. Tools for CNC machinery are manufactured by a variety of brands and come in several ANSI standards.
