Why should you never exceed a chip length of more than 2-3 inches while drilling?

Maintaining a chip length of no more than 2-3 inches while drilling is essential for several interconnected reasons.

First, shorter chips help prevent jamming, which can happen when chip lengths exceed this range. Longer chips can become trapped in the drill area or in the tool's mechanisms, leading to operational interruptions, increased friction, and potentially damaging the equipment.

Second, regarding drill wear, longer chips can cause the drill bit to encounter greater resistance and friction. This increased resistance not only accelerates the wear of the drill bit but may also lead to overheating. Proper chip length aids in improved cooling and chip evacuation, thus extending the life of the tool.

Lastly, there are significant safety considerations. Extended chips may pose a risk during the drilling process by becoming projectiles if dislodged, or they can obstruct visibility and control around the drill site. Maintaining the proper chip length minimizes these dangers, fostering a safer working environment.

By ensuring chip lengths are kept within this recommended range, you enhance the efficiency of drilling operations, prolong the lifespan of tools, and significantly improve safety on the job site.
