Best for the Spoil Board (Fly) Cutter, all Insert Tools and Diamond Tools. Improved efficiencies over standard tool holders, increases tool life and improves finish. Not suitable for solid carbide tools and tools requiring frequent change since an additional investment in a heat induction unit is required.
