Double Margin Cobalt Drill Bits with Pilot
Double Margin Cobalt Drill Bits with Pilot
Double margin drill bits have an additional margin ground behind the leading margin, providing twice the number of contact points. This second margin performs various functions to improve hole quality. The trailing margin burnishes the cavity, making a true hole and smoother finish, helping to provide a more concentric drilled hole.
