A TG collet (Tapping Collet) is a heavy-duty tool holding collet designed for high torque applications such as tapping, drilling, and reaming.
It offers strong gripping force and rigidity, making it ideal where ER collets may slip.
Standard: DIN 6499 / ISO compatible (TG series)
🔹 KEY FEATURES
Very high gripping force (anti-slip)
Excellent rigidity for tapping operations
Wide clamping range (larger than ER)
Long service life
Interchangeable with standard TG chucks
