What should be done during the tapping operation to prevent jamming?

During the tapping operation, it is important to prevent the tap from jamming within the hole being threaded. One effective method to achieve this is to periodically rotate the tap counter-clockwise. This technique helps to break free any material that might be causing the tap to bind, ensuring a smoother operation. The counter-clockwise rotation essentially serves to dislodge any chips or debris that could become trapped, facilitating a clear path for the tap and reducing the risk of jamming.

Utilizing this method not only promotes a more efficient tapping process but also extends the life of the tooling by minimizing wear and tear caused by friction and binding. Proper chip removal is critical in maintaining the performance of the tap, as built-up debris can lead to increased pressure and potential breakage.

Other methods such as increasing rotational speed, using a higher torque setting, or applying more lubricant might not effectively address the core issue of jamming, which revolves around chip removal and the prevention of material obstruction. Thus, rotating counter-clockwise periodically stands out as the recommended practice for ensuring a successful tapping operation without jamming.
