BT 30 BT40 Precision ER Tool Holders for CNC Machines
BT30-ER32 Tool Holders, BT40 ER Toolholders

Like CAT Tooling, BT Tooling comes in a range of sizes designated as BT 30, BT 40, BT 50, etc. and uses the same NMTB body taper as CAT 40. BT tooling is symmetrical about the spindle axis, which CAT tooling is not. This gives BT tooling greater stability and balance at high speeds. BT Tool Holders will accept both Imperial and metric sized tools. BT Tooling looks very similar and can easily be confused with CAT tooling. The difference between CAT and BT is the flange style, thickness, and the thread for the pull stud is a different size. BT Tool Holders use Metric thread pull studs (retention knobs).

CNC Milling Collet Chuck Holder Tools:
There are two types of tools in CNC machinery: tool holders and cutting tools. There are other items related to tool holders, such as collets, set screws, wrenches and other setup tools. Tools for CNC machinery are manufactured by a variety of brands and come in few different standards.
BT standard for tool holders originated in Japan and is somehow similar to CAT tool holders. As well as CAT tool holders, it has numerical designations that correspond to the size of the taper: BT-30, BT-35, BT-40, BT-45, BT-50. The higher the number is, the bigger is the taper.
If to compare BT to CAT tool holders – they look very similar and can be easily confused, however, they has different flange system and its thickness is different too. Also, the retention knobs are different. Therefore BT and CAT tool holders are not interchangeable. 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. That makes BT tool holders better balanced and more stable at higher speeds.
BT tool holders along with CAT, ISO and HSK standards are among the most used in CNC machinery. They will accept both imperial and metric sized tools; however, BT tools come in metric sizes. They are durable and are best choice for very high speed machinery. BT tools allow to use ATC (Automatic Tool Change) technology to maximize the speed and productivity of manufacturing. Though tool holders are performing work with high strains and pressures, be sure to store them safely without any chance for the tool being damaged – as this may cause some misbalance that can be critical at high speeds and precise CNC machinery.
