When deburring holes, how should you apply pressure to the tool?

When deburring holes, applying light pressure while twisting the tool clockwise is the most effective method for achieving a clean and smooth edge. This technique allows for controlled material removal, which is crucial to avoid damaging the base material or the surrounding areas. By using light pressure, you can better monitor the tool's interaction with the surface, minimizing the risk of over-deburring or creating unwanted burrs.

Twisting the tool in a clockwise direction is significant because it aligns with the natural cutting action of most deburring tools, which are designed to cut in that direction. This alignment enhances the efficiency of the deburring process, allowing for optimal shaping of the hole's edges. Proper technique not only improves the precision of the deburring but also ensures that the tool's life is extended since excessive force can lead to premature wear or breakage of the tool.

In contrast, other methods, such as applying maximum force or using counter-clockwise twisting, may result in uneven burrs or damage to the workpiece. The use of even pressure without twisting might not effectively remove the material, leading to inadequate finishing. Thus, the recommended approach emphasizes careful control of pressure and direction, aligning with best practices in aerospace assembly and maintenance.
