MK Tools solid-carbide round tools from Monaghan Tooling Group introduces new "Speed-Drill R4" geometry, reportedly offering unparalleled cutting speeds and unprecedented tool life when cutting gray cast iron, ductile iron and forged steel, which are popular materials in automotive engine and chassis components. With a new corner radius design which is tangential to the drill point but nontangential to the diameter, these proven designs address challenging, high production drilling applications.
