- Fit all Haas ER collet chuck holders
- Ensure that 100% of through-tool coolant gets to the tip of the cutting tool
- Approved for high-pressure coolant to 1100 psi
- Short rear collet slots provide a mechanical seal, blocking coolant flow
- Mechanical seal design is superior to silicone/rubber sealed collets
- Do not require a coolant ring or special ER nut
NOTE: Steel sealed collets seal best when using the maximum size shank in the collet. To seal properly, the entire shank must be in the collet and cover all slots.
