Router Extension Holder with ER Collet - Options
Adapt the holder arrangement in a router setup that permits an extension. This spring-steel accessory family combines extension-shank and ER collet selections for matching tooling.
✅ Position a suitable cutter farther from the holder - An approved extension arrangement provides additional reach within the machine's limits.
✅ Match the cutter shank through the selected collet - ER16 and ER20 options provide different collet arrangements for a supported tool setup.
Check Every Interface Before Use
Match the machine shank, ER format, cutter diameter and permitted speed to the actual selected assembly. Extra overhang changes the tool arrangement, so use an extension only where the machine and tooling instructions permit it.
The family includes quarter-inch, 8 mm and half-inch shank options with different collets or packages. Select by all fitting dimensions rather than assuming every pictured collet is included.
