Get More Out of Your Vertical, Horizontal, and 5-Axis Machining
- These multi-function fixtures enable you to use Royal QG collets, Royal I.D. mandrels/sleeves, and 5C collets in your 3, 4, and 5-axis applications.
- Manually actuated with a hex key (included).
- Many of the same great features as our QG Combo CNC Collet Chucks, including ten-second collet changes and parallel-grip collets with a full 0.062″ clamping range.
- Can be used in both stationary and rotary table applications. Caution – not for use on lathes or grinders above 5 rpm!
- Pullback design with an internally threaded backplate enables the use of a stop rod.
- Unit is supplied configured to accept Royal QG collets. For I.D. and 5C workholding, additional components are required (order separately).
How It Works
- Royal QG Power-Block™ Combo Fixtures directly accept Royal QG collets.
- For I.D. and 5C applications, a hardened and ground adapter (sold separately) is inserted and bolted to the fixture and engages with the piston via a bayonet arrangement.
- This adapter has a ground 75mm I.D. recess to accept Royal I.D. mandrels or our 5C collet nose.

ROYAL ULTRA-PRECISION QUICK-GRIP™ COLLETS
Why Do Top Manufacturers Insist on Royal Quick-Grip™ Collets?
Industry-Leading 0.062" (0.080” for QG-100) Gripping Range Covers More Diameters with Fewer Collets
Ultra-Precision Accuracy – 0.0002" TIR or Better
Vulcanization Guaranteed for Life
Parallel-Grip Maintains Full-Length Part Engagement
Exceptional Grip-Force Enables Very Aggressive Cutting
Exclusive Royal Risk-Free Performance Guarantee
Fast Delivery on Custom Shapes and Sizes
Special Slot Relief Grinding Eliminates "Collet Popping" and Minimizes Chuck Wear
These Extremely Advanced Collets Will Revolutionize Your Workholding
- Industry-leading 0.062" Gripping Range (0.080" for QG-100) – greater than other quick-change collets on the market and more than 12X that of traditional spring collets.
- Royal Quick-Grip Collets are precision-ground to nominal size, with a gripping range of ±0.031" (0.040” for QG-100) to handle undersized/oversized stock.
Example – a ½" QG-65 collet is ground to 0.500" dia., and can hold any part ranging in size from 0.469" – 0.531" dia. - Ultra-Precision Accuracy – 0.0002" TIR or better guaranteed on round-bores. Total system accuracy (chuck + collet) guaranteed to 0.0004" or better.
- All Royal Quick-Grip™ Collets are designed for minimal projection beyond the chuck face (≤ 0.020") for optimum rigidity and machine work-zone utilization.
- All models have a smooth gripping surface, but round-bores are also available from stock in a double-serrated version for very aggressive first-op machining.
- Vulcanized rubber between the hardened steel collet segments provides outstanding protection against coolant and chip penetration, and Royal’s advanced vulcanization process carries a lifetime guarantee against failure.
- Collets can be counter-bored for increased capacity.
- S-type master collets available for QG-65 and QG-80 chuck models.
- Royal Quick-Grip™ Collets are compatible with some other brands of quick-change chucks, but note that the QG-80 and QG-100 models have a six-slot design (for increased gripping torque) that requires the use of a Royal installation tool. Call us to verify compatibility.
- Custom sizes and shapes available as quick-ship specials. Collet segments can also be carbide-coated for extremely harsh applications. Contact one of our applications engineers at 1-800-645-4174 to discuss your requirements.
