    • General purpose tool for cast iron, copper, brass and steels
    • Fairly aggressive cutting action, with good material removal rates
    • This tool leaves a nice finish on most all materials, but the bite can be demanding on operators 
    • For general purpose use including cast iron, copper, brass and steels
    • The Doublecut utilizes a cross flute of exactly half the number of standard flutes in a opposing helix
    • Sliver size is greatly reduced, as is the operator fatigue from the balanced cutting forces
    • Lower RPMs may be utilized with little negative impact on performance 
    • The decreased load equates to operator's often feeding this tool more aggressively 
    • Best for all non-ferrous, non-metallic workpieces like aluminum, zinc, plastic, wood, etc. 
    • An extremely aggressive cutting action, with little or no chance of plugging these flutes up 
    • Is a finer cut of opposing helixes 
    • Operating control is very good because the biting action is limited as is the silver size produced from it 
    • This version tends to be preferred in shops where titanium and other difficult materials (superalloys) are being deburred
    • With the teeth being smaller and slightly more fragile as a result, tool life is not usually a matter of import
    • Fiberglass tends to cut nicely with Diamondcut
    • Another version of the Doublecut, this is a slightly less aggressive tool whose main purpose is to simply interupt the cut
    • One single, opposing helix is ground in a spiral around the tool, typically 
    • Silver size goes down, surface finish goes down marginally, hand control goes up, marginally
