Customer Reviews:

Excellent for Fiberglass [Posted on 2007-01-11]
You'd think a straight router bit would be just fine for fiberglass but it tends to melt the plastic more than cut it. This bit kinda chips the piece to cut it, leaving little or no mess and melting. A great choice for this application.
