Re: interesting negative rake tools

Ralph Lindberg
Background... I am friends with both Dave (founder of D-way) and Jimmie (founder of Boxmaster)

When Jimmie was developing Boxmaster NRS he worked closely with Dave for the process and metal. So he certainly could have gone with M42, but they decided for this application that M2 worked better.

Now Boxmaster tools are not heat-treated the same way as most M2, they (Jimmie and Dave) developed a process based on Dave's heat-treat for M42.
The result is Boxmaster test out harder (Rockwell) and more wear resistant the other M2 tools. The heat treat plant they use also produces a more consistent heat-treat (considering who they heat-treat for... the aero-space industry) then most plan "tool" shops.
