Cutting Edge Length S 4.2 4.4 For general purpose Good chip control Large machining Description TKFB16R38.. TKFB16L38.. Cutting Edge Length S 5.8 6.2 Large ap at one pass How to select back turning toolholder hand Selection =n Small machining TKFB12R15.. In case ap is same, if the insert with narrower edge width is used, overhang length from the guide bush is shorter, which enables better stability due to less workpiece deflection. High precision machining 1.5 Right-hand Guide bush E Machining near the guide bush is possible Narrow cutting edge width of TKFB12R15005M "Optimum for small parts and high precision machining Left-hand The workpiece b contact the guide Guide bush urr does bush. not burrs S' & Machining with a distance from guide bush Good chip control due to large space between the guide bush and the tool. "Excellent chip control in roughing and finishing (plural passes) Stable accuracy of external diameter dimension: When burrs occur, if a Left-hand toolholder is used, it is not necessary to return workpiece into guide bush in finishing. Also, Left-hand toolholders prevent guide bush wear caused by chip biting. Workpiece movement and tool hand selection In roughing and finishing Good dimension accuracy: If a Left-hand toolholder is used, burrs on workpiece generated in roughing do not damage the guide bush in finishing.
