The TG150 collet system provides a 3:1 gripping advantage for high-accuracy applications, including tapping and drilling. Technical specifications indicate a projection or gage length of 5.5 inches (represented by the 55 suffix in the model number). The holder includes a collet lock nut and is compatible with TG150 collets which offer a clamping range of 1/64 inch and a typical TIR of 0.0004 inch. The system supports cylindrical shanks with squares, and the collet design includes a slot that acts as a drive for tap squares to ensure reliable torque transmission.
