How should the drill be operated when working with hard composite material?

When drilling into hard composite materials, operating the drill at full RPM (Revolutions Per Minute) is critical for maintaining the efficiency of the drilling process. High-speed drilling helps to ensure that the cutting tools engage the material effectively, creating clean, precise holes. This is especially important with composites, as their layered structure can be sensitive to heat and pressure.

Drilling at full RPM facilitates the removal of debris and minimizes the chance of the drillbit binding in the material. It also helps prevent delamination, which is a common issue when working with composites, as it can lead to a compromised integrity of the material. Additionally, a higher speed aids in reducing the friction generated during drilling, which can further protect the composite layers from damage due to excessive heat buildup.

On the other hand, options that suggest lower speeds might compromise the effectiveness of the drill and could result in overheating or excessive wear on the drill bit, undermining the objective of achieving clean and efficient hole creation.
