The Difference Between HSK and BT Tool Holders in CNC Spindles

What's the Difference? 

The tool holding technology can largely determine the performance of the machine. There are typically two popular tool holder types utilized in CNC spindles: the HSK (Hollow Shank Taper) and BT (Taper Shank) tool holders. Both come with their own pros and cons, but the key to decide whether you should opt for a R8 or an MT3 tool holder depends on what you want your machine to achieve. 

HSK Tool Holders are Better for your CNC Spindle

In comparison to BT tool holder, the HSK tool holders is now commonly used in CNC industry for its high performance and stability. Increased rigidity and such accuracy constitutes to the major reasons why HSK tool holder are being favored. HSK tool holders with their hollow shank are bringing greater concentricity and clamping force, thereby less vibration to the table which also can help for a better surfaces as well. In addition HSK tool holders have a more robust taper-to-taper contact than BT tool holders for higher dimensional accuracy and repeatability when machining. 

Benefits of BT Tool Holders for Wholesale CNC Buyer’s

Although HSK holders perform very well, BT tool holders have their own benefits that managed to keep them in wide use among wholesale CNC client. One of the benefits of BT tool holders is their wide availability and compatibility with many CNC machines. BH tool holders are also some of the most affordable on the market today, making them a great choice for businesses that want to maximize their machining functions without bending over backwards. Moreover, BT tool holders are easier to maintain and replace to save your time and increase efficiency for your machine. 

Picking the Proper Tool Holder for Your CNC Machine

When selecting the most appropriate tool holder for your CNC machine, you need to take into consideration your specific machining needs and budget. If your machining is characterized by precision, accuracy, surface finishes, HSK could be the best investment for you. If, however, you require a low-cost holder that is universal and easy to be maintained, BT holders might be the right choice for your application.
