Features
- 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
- Heavy Duty Construction - Royal ER Collets are made from high-grade steels imported from Germany and are hardened for long life
- 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. 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
