Decoding the full part number: GT106 identifies the series (solid carbide internal grooving bar); 4758 encodes the shank diameter as 4.758 mm (approx. 3\/16 in) and overall length characteristics; .015 specifies the groove width (cutting edge width) of 0.015 in (0.381 mm); .25 specifies the minimum bore diameter of 0.25 in (6.35 mm); .60 specifies the usable\/bore depth reach of 0.60 in (15.24 mm); R indicates a right-hand cut orientation; and U1 denotes the carbide grade designation used by Gühring for this tool family. The tool features a reduced-diameter neck ground ahead of the shank to maximize reach into small-diameter bores, a single-point ground cutting tip geometry optimized for internal groove\/snap-ring groove cutting on CNC lathes and screw machines, and the characteristic dark DLC\/PVD-type coating visible in the photos for improved wear resistance and chip evacuation in steel, stainless, and aluminum applications. Compatible with standard cylindrical boring bar holders accepting a 3\/16 in round shank.\u003c\/p\u003e\n\u003ch3
