The 1-1/2 MIN BORE LEFT HAND A-D-D UNIVERSAL INDEXABLE BOARD INDEXED BORING BAR with TiAlN Coating, 60 DEGREE DIAMETER (0.593 D), BUTTON HEAD COOLANT THRU is an advanced precision boring tool designed to provide exceptional performance in demanding machining operations across various industries such as automotive, aerospace, construction, and military engineering applications. Manufactured with ISO standard bores, this boring bar offers greater accuracy and reduced vibration for prolonged usage due to its lightweight composition coupled with the rigidity of TiAlN coating surface treatment against wear and tear. It further enhances ease-of-use by featuring an indexable insert that permits easy resharpening, increasing cost efficiency in comparison to solid boring bars. The boring bar is specifically designed for use with left-hand threads allowing better accessibility while machining in tight spaces or limited workpiece geometries like the automotive engine block bore processing without sacrificing precision and reliability on every pass.
