Cutting Edge Length s 0.165" TKFB12L28.. 0.173" For general purpose Good chip control For Large D.O.C. Part Number Cutting Edge Length s TKFB16R38.. 0.228" TKFB16L38.. 0.244" For Small D.O.C. TKFB12R15.. D.O.C. per pass is large. Choosing Hand of Back Turning Toolholder For General Purpose TKFB12R28.. In case D.O.C. is same, if insert with narrower edge width is used, overhang length from guide bushing is shorter, which enables better stability due to less workpiece vibration. High Precision Cutting (R) Right-hand Cutting close to guide bushing is possible Since TKFB12R15005M has a narrow cutting edge (width=0.059"), cutting close to guide bushing is possible Good for small parts and high precision cutting (L) Left-hand Even if burrs occur, they will not return into the guide bush. Cutting with distance from guide bushing Good chip control due to large space between the guide bushing and the tool. Howto improve chip control for roughing to finishing In case of using a left-hand toolholder in finishing, the burred portions of workpiece do not return into the guide bushing, which enables stability of external diameter. Also, a Left-hand toolholder prevents wear of guide bushing due to chip biting. Workpiece Material Motion & How to Select Hand of Tool When Roughing, Medium, & Finishing 5 Good dimensional accuracy: If a Left-hand toolholder is used, burrs on workpiece generated during roughing do not damage the guide bushing during finishing.
