Frequently Asked Questions

Q What is the difference between HSK-A-TPM, BT-TPM, and SK-TPM tapping chucks?

The HSK-A-TPM, BT-TPM, and SK-TPM tapping chucks differ primarily in their shank interface type. HSK-A uses a hollow taper shank for high-speed and high-rigidity applications, BT uses a dual-contact V-flange shank suitable for standard machining centers, and SK uses a steep taper shank designed for specific spindle configurations. All three series support the same TPM collet system and tapping capacity ranges.

Q What tapping capacity range do the TPM tapping chucks support?

The TPM tapping chucks are available in two collet size ranges: TPM316 supports tapping from M3 to M16, and TPM830 supports tapping from M8 to M30. This covers a wide range of threading applications for both light and heavy-duty machining.

Q Are the collets included with the tapping chuck purchase?

No. Collets (TPD316 and TPD830) are not included with the tapping chuck and must be ordered separately. Please specify the required collet model when placing your order to ensure compatibility with your tapping capacity needs.

Q Which collet should I choose for the TPM tapping chuck — TPD316 or TPD830?

Choose TPD316 if your tapping work involves thread sizes from M3 to M16. Choose TPD830 if you need to tap larger threads from M8 to M30. The TPD830 collet also has a larger body diameter (D=66mm) compared to TPD316 (D=50mm), which provides additional rigidity for heavy-duty tapping operations.

Q What does "High Rigidity" mean for the TPM tapping chuck series?

"High Rigidity" in the TPM series refers to the chuck's structural design that minimizes deflection and vibration during tapping operations. This ensures better thread quality, improved tool life, and consistent performance — especially important when tapping harder materials or at higher spindle speeds.

Q How do I select the right TPM tapping chuck size for my machining center?

Select the chuck based on your machine spindle interface: use HSK63A or HSK100A for HSK spindles, BT30/BT40/BT50 for BT-type spindles, and SK40/SK50 for SK-type spindles. Then choose the appropriate collet model (TPM316 or TPM830) based on your required tapping range. Refer to the specification tables above for exact dimensions including overall length (L), gauge length, and weight to ensure proper fitment.
