Royal Quick-Grip™ S-Type Master Collet
QG-65, S-20 Pad Model

Occasionally, customers express interest in using S-type collet pads to grip their parts. Although this outdated technology is typically not the best choice for most workholding applications, S-type collet pads can be utilized with Royal Quick-Grip™ CNC Collet Chucks via our Quick-Grip™ S-Type Master Collets. These master collets are available for Royal QG-65 and QG-80 chuck models, and are capable of accepting S-20, S-26, and S-30 collet pads.
Three master collet models to choose from:
- QG-65 Master Collet – accepts S-20 collet pads (2" capacity)
- QG-80 Master Collet – accepts S-26 collet pads (2-5/8" capacity)
- QG-80 Master Collet – accepts S-30 collet pads (3" capacity)
It is important to note that the master collet must be installed in the chuck prior to pad installation, thereby mitigating the system’s quick-change advantage.
Royal QG-80 master collets contain four segments instead of our traditional six, requiring the use of a special four-segment changing tool (sold separately below). The model 65 utilizes the same installation tool as our standard QG-65 collets.
Due to the stacking of tolerances and complex geometry, the use of S-type collet pads will result in a significant reduction in accuracy. Most S-pad manufacturers will not guarantee their pads to run better than 0.001" – 0.0025" TIR. By contrast, Royal hardened and ground Quick-Grip™ collets are guaranteed accurate to 0.0002" TIR.
The use of S-type pads reduces overall Quick-Grip™ chucking capacity. See chart below.
| Chuck Model | S-Type Pad Model | Maximum Pad Capacity | Master Collet Part Number |
| QG-65 | S-20 | 2.00" | 44196 |
| QG-80 | S-26 | 2.63" | 44197 |
| QG-80 | S-30 | 3.00" | 44198 |
* Please note – normal thru-capacity is reduced when using S-type master collets and pads.
** S-type pads not included with master collet. Order pads separately.
The Bottom Line
Using S-Type Collet Pads in a Royal Quick-Grip™ Collet Chuck may come in handy for some jobs, but their use will eliminate the quick-change feature and cause a reduction in both gripping capacity and overall system accuracy. For the highest accuracy, best performance, and full Quick-Grip™ functionality, it is always best to utilize hardened and ground Royal Quick-Grip™ Collets.
