Installation notes
Disconnect power and engage the spindle lock. Remove the collet nut and the worn collet. Inspect the spindle taper for scoring; clean it if needed. Press the new collet into the nut, insert a router bit, and tighten the nut to the torque specified in your router’s manual. A properly seated collet should grip the bit with no play.
Common questions
Q: Will this 1/2” and 1/4” router collet fit my DeWalt DW618, or is it only for the DW621/DW622 series?
Yes, this collet is made to fit the DeWalt DW621, DW616, DW618, DW622, and DW626 routers. If you have a DW618, it should fit correctly as long as your router still has the original collet nut and spindle setup.
Q: Can I use both 1/2” and 1/4” shank bits with this collet, and do I need to seat the bit all the way in?
This replacement collet is intended for both 1/2” and 1/4” router bit shanks, depending on the collet size you install. When inserting a bit, slide it in fully and then back it out slightly before tightening, which helps the collet clamp more evenly and reduces the chance of the bit sticking after use.
Q: What’s the best way to maintain this collet on a DeWalt DW626 so it keeps gripping properly?
Keep the collet and collet nut clean and free of resin, dust, and metal debris, because buildup can affect how well it grips the bit. If you notice slipping, remove the collet and clean both the inside taper and the bit shank, and replace the collet if you see cracks, distortion, or uneven wear.
