- 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.AdvantagesUltra-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
