Q1: What is J41?
A: Split quick change torque protection tapping chuck, with chuck body and independent quick change collet.

Q2: Core mechanisms?
A: Axial pitch compensation + overload torque protection.

Q3: Pitch compensation function?
A: ±5mm standard compensation, auto-matches thread pitch, prevents thread disorder, suitable for blind and deep hole tapping.

Q4: How does torque protection work?
A: Automatically slips when resistance exceeds limit, prevents tap breakage, reduces tool wear.

Q5: How to adjust release torque?
A: Adjust the tail nut for different diameter taps.

Q6: Suitable machines?
A: Bench drill, vertical drill, lathe, milling machine, machining center, rocker drill, CNC tapping machine.

Q7: Main material?
A: 65Mn spring steel, quenched HRC44~48, wear-resistant and impact-resistant.

Q8: Handle types?
A: MS2/MS3/MS4/MS5, R8, BT30/BT40/BT50, straight handle C-type.

Q9: J41 vs GT/J42?
A: J41 split quick change, no need to disassemble body when changing tap, for batch processing; GT/J42 integrated, requires full disassembly, for simple bench drills.

Q10: Torque adjustment?
A: Reduce torque for aluminum, increase for steel and stainless steel.

Q11: Compensation range?
A: ±5mm standard axial compensation.

Q12: Applications?
A: Batch threading, deep hole tapping, blind hole tapping.

Q13: Model selection?
A:
