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 How to select back turning toolholder hand Machining near the guide bush is possible Narrow cutting edge width of TKFB12R15005M (1.5mm) allows it. Optimum for small parts and high precision machining Right-hand Guide bush The workpiece burrs do not contact the guide bush. burrs Left-hand Guide bush 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.
