The Micro 100 RS-250-14 is a solid carbide right-hand single-point boring bar manufactured in the USA from Micro 100's "Super Carbide" submicron grain carbide substrate, designed for internal turning and bore finishing on CNC and manual lathes. The part number decodes as follows: RS = Right-Hand Single-Point boring bar style; 250 = 0.250 in (1/4 in) shank diameter; 14 = 14° lead angle. The tool features Micro 100's proprietary black PVD coating visible on the cutting head, which improves wear resistance, reduces built-up edge, and extends tool life in ferrous and non-ferrous materials. This bar is suited for boring small-diameter holes and is compatible with standard 1/4 in bore toolholders and boring bar blocks. Offered here new in the original Micro 100 orange plastic case.
