The Micro 100 BB-3201600SG is a new solid carbide right-hand boring bar from Micro 100's "Super Carbide" line, manufactured in the USA and finished with a TiN (Titanium Nitride) coating visible as the gold color on the bar body. Decoding the part number BB-3201600SG: BB = Boring Bar, 320 = 5/16 in (0.3125 in) shank diameter, 1600 = 1.600 in bore depth / overall usable reach, SG = Single-Point Ground geometry with a TiN coating. The 5/16 in cylindrical shank fits standard boring bar toolholders and CNC lathe turrets, and the single-point ground carbide tip provides consistent geometry for internal diameter turning, back-boring, and finishing operations in steel, stainless, aluminum, and non-ferrous materials. TiN coating improves surface hardness and lubricity, extending tool life versus uncoated carbide in general-purpose applications.
