The wrench supplied with this item only works if you are using straight bits. Bits with "wings" such as cove or ogee type bits will not let you get the wrench between the bit and the collet nut to tighten or loosen the nut. I ended up having to use a pair of channel lock pliers to tighten. the nut.
