Scientific Cutting Tools’ 1/2" Right-Hand Triangle Insert Indexable Boring Bars with Coolant Holes are built for heavy-duty internal machining with enhanced thermal and chip control. Featuring a robust heat-treated steel head and precision-ground carbide shank, these tools provide the strength and rigidity required for deeper or interrupted cuts. The integrated through-coolant channel helps evacuate chips and reduce cutting temperatures, improving tool life and surface finish. Designed for triangle-style inserts, these bars are a smart choice for production environments and high-performance applications.
