What Is the Difference Between BT, CAT, and HSK Toolholder Systems?
Choosing the right toolholder system is essential for achieving accuracy, stability, and productivity in CNC machining. The toolholder connects the cutting tool to the machine spindle, and its design affects tool retention, rigidity, machining performance, and compatibility. Three widely used CNC toolholder systems are BT, CAT, and HSK. Although they serve the same basic purpose,
