Ultra-Precision ER Collets
Inch and Metric Sizes
Royal ER Collets are available in both inch and metric sizes. This optimizes the surface contact between the collet and cutting tool and results in higher accuracies, stronger grip force, better part finishes, and longer cutting tool life.
Extremely Accurate
Runout is guaranteed to be 6 microns (0.0002″) TIR, or better. Each collet is inspected to this standard prior to shipping.
Heavy Duty Construction
Royal ER Collets are made from high-grade steels imported from Germany and are hardened for long life.
Sealed Models Available
For precise coolant delivery to the tip of the cutting tool.
Large Inventory
All sizes are in-stock, ready for immediate shipment.
Wide Gripping Range
Royal standard ER Collets contain 16 slots, providing a larger gripping range than other brands.
Great Value
Very competitive prices make these high-quality ER Collets the best value in the industry.
Royal Sealed Ultra-Precision ER Collets
- Ultra-Precision Accuracy – 0.0002″ TIR guaranteed.
- High-pressure approved to 1400 psi.
- Unique design is mechanically sealed by virtue of the rear slots terminating prior to the annular groove, completely blocking the path of coolant flow to the front of the collet.
- When using thru-coolant cutting tools, these collets ensure 100% coolant delivery to the tip of the cutting tool.
- Superior to collets sealed with silicone/rubber plugs because plugs are limited to lower operating pressures and are subject to wear.
- Unlike standard ER collets, sealed models do not have a wide collapsibility range, requiring the collet bore to be matched to the cutting tool shank diameter.
A Perfect Match to Your Cutting Tool Diameter
All Royal ER Collets are available from stock in both inch and metric sizes. This is very important because it enables you to select a collet that has been ground to your precise cutting tool size.
Using a collet that is perfectly matched to the cutting tool diameter ensures that full surface contact is achieved, resulting in higher gripping force, better accuracy, less vibration, better surface finishes, and longer tool life.
