* Threaded-nose collet chucks are for use with 5C step collets that close on the head, not the 10-degree angle. Never exceed the manufacturer’s rpm and drawbar force limits for any threaded accessories.

Royal Low-Profile Pullback CNC Collet Chucks

Simple Design

Royal Low-Profile Pullback CNC Collet Chucks provide a simple, low-cost method for utilizing collets on all CNC lathes and turning centers.

Spindle Bearing Protection

An oversized flange acts as a coolant slinger to protect lathe spindle bearings from contaminants. An internal O-ring protects sliding components from coolant and fines.

High RPM

All Royal CNC Collet chucks are balanced by design for high-speed operation, and can often be run at higher speeds than conventional 3-jaw chucks because they are less prone to the negative effects of centrifugal force.

Easy Installation

All Royal Low-Profile Pullback Chucks include a collet wrench, mounting hardware, mounting wrenches, and a custom-machined drawtube connector to ensure hassle-free installation.

Wide Range

Royal manufactures a wide range of chucks to fit all popular spindle noses and collet styles. Gripping capacities range from 1⁄64″ to 1-3⁄4″ diameter.

Heavy-Duty Construction

All chuck components, except for the drawtube connector, are hardened to Rc 61-63 for rigidity and durability.

High Accuracy

All Royal Low-Profile Pullback CNC Collet Chucks are guaranteed to run within 0.0002″ TIR.

Adjustability

Dual collet retaining screws ensure easy collet installation and adjustability.

Low-Profile

All external dimensions have been optimized to provide outstanding tool clearance and rigidity.

Specials

If you have a special application that goes beyond the scope of our standard line, we will be happy to design and build a custom system to meet your needs. Please contact a Royal applications engineer to discuss your requirements.

For capacities greater than 1.75", choose the appropriate Royal Quick-Grip™ CNC Collet Chucks.  Quick-Grip™ CNC Collet Chucks offer many advantages over Low-Profile Collet Chucks, including superior tool clearance, parallel-grip functionality, and better price-points.

If you would like to continue utilizing older technology S-type collet pads, you can do so with the use of our Quick-Grip™ master collets.
