How to Install a Router Bit
Learn the right way to install a router bit for safer woodworkingInstalling a router bit correctly requires more than just tightening a collet nut. A router’s collet is designed to draw the tool’s bit in towards the motor. Allowing the bit’s shank to bottom out inside the tool can result in a bit that works its way out of the collet while spinning at high speed. Not only can this ruin a beautiful workpiece, it can spark a safety disaster.
In this Wood Tips video, Fine Woodworking senior web producer Ed Pirnik demonstrates the right way to install a router bit, resulting in a tight grip that will keep you out of harm’s way.

It can be difficult to remove a bit that's stuck in the collet. The 1/8 clearance that Pirnik recommends lets you tap the bit down slightly and that movement often frees it up.
Saved me having to buy a new router. No matter how much I tightened it, mid way through my board my bit would rise up. Wife was convinced I needed a new router as this was an old Craftsman from Sears that my grandfather owned and I already fixed it once when the height adjustment lock broke on it. Thank you for making this make sense. So simple really.
My solution to this problem was to purchase some “O” rings in 1/4 and 1/2 diameter and slip an appropriate size on the shaft of each of my router bits to present them from seating. Problem solved.
I have a 3/8 rubber O ring in the bottom of the collet on my table mounted router so the bit is automatically seated just a little off the bottom. It's always there so I don't need to think about it. As the chuck pulls the bit down it compresses the rubber. Another advantage is matched sets of router bits are always the same height off the router.
It would be helpful if your videos had closed captioning capability. I don’t get a lot from them otherwise.
