The cutting edge is on the right side. Since the tool carriage can move both—left and right directions, so it is necessary to preset the cutting tool on the tool post based on desired direction of movement. Of course, that's meant turning in the conventional manual riggt, I. Facing the shaft on the left side, you'll see a lathe tools right hand vs left hand jacket handed thread. Joined Feb 28, Messages On the other hand, notice that when right-hand tools are used, the force of the machining operation tends to pull the turret away from the machine bed, and machining is less stable. With CNC turrets in the rear, I tooks the definition of the terms has blurred if my understanding was ever correct, that is.

Many shops use them exclusively. Keep in mind, however, that your turning center's rigidity and strength will commonly be better with left-hand-tooling. The drawing here shows why. Notice that when left-hand tools are used, the force of the machining operation is thrown into the machine's bed and machining will be very stable. On the other hand, notice that when right-hand tools are used, the force of the machining operation tends to pull the turret away from the machine bed, and machining is less stable.

For light duty machining, it truly doesn't matter which type of tooling you use. But as machining operations become more powerful as is the case when performing heavy rough turning and boring operations , left-hand tools are better.

These are cutting motion and the feed motion. These motions can be imparted either on cutting tool or workpiece or on both.

In case of turning operation, carried out on lathe, cutting tool called single point turning tool—SPTT is mounted on tool post and the entire tool post moves by various mechanical arrangements to provide necessary feed motion. Since the tool carriage can move both—left and right directions, so it is necessary to preset the cutting tool on the tool post based on desired direction of movement. For two different directions, two different tools are required, and accordingly SPTT can be classified into two categories—right handed cutting tool and left handed cutting tool.

Note that the concept of left hand and right hand tools is commonly applicable for single point cutters like lathe and boring tools.
