Frequently Asked Questions
-
Q What is the difference between HSK-A-TPM, BT-TPM, and SK-TPM tapping chucks?HSK-A-TPM chucks use an HSK-A spindle interface (HSK63A or HSK100A), which offers higher rigidity and faster tool changes for modern machining centers. BT-TPM chucks use the BT shank interface (BT30, BT40, BT50) widely used in conventional CNC machines. SK-TPM chucks use the SK (steep taper) interface (SK40, SK50), suitable for high-speed spindles. All three series support the same TPM tapping chuck body and TPD collet system.
-
Q Do collets come included with the tapping chuck?No. Collets (TPD316 or TPD830) must be ordered separately. Please select the appropriate collet based on your required tapping capacity — TPD316 for M3–M16 and TPD830 for M8–M30.
-
Q What tapping capacity range do these chucks support?The TPM316 series supports tapping from M3 to M16, while the TPM830 series covers M8 to M30. This makes them suitable for a wide range of threading operations in both light and heavy-duty machining applications.
-
Q What does "High Rigidity" mean for these tapping chucks?High rigidity means the chuck body and interface are engineered to minimize deflection and vibration during tapping operations. This results in improved thread quality, longer tap life, and the ability to handle larger diameter threads with greater accuracy and consistency.
-
Q How do I choose between TPM316 and TPM830 for my application?Choose TPM316 if your tapping range is M3–M16 (smaller diameter threads, lighter cuts). Choose TPM830 if you need to tap M8–M30 (larger diameter threads requiring greater torque capacity). Note that TPM830 has a larger chuck diameter (D=66mm) compared to TPM316 (D=50mm), so verify spindle clearance before ordering.
-
Q Are these tapping chucks compatible with standard CNC machining centers?Yes. The HSK-A, BT, and SK interfaces are all industry-standard spindle connections widely supported by CNC machining centers from major manufacturers worldwide. Always verify the spindle taper type and size (e.g., BT40, HSK63A, SK50) of your machine before selecting the appropriate chuck model.
