When deburring with the open countersink cutter, what type of pressure should be applied?

When using an open countersink cutter for deburring, applying light pressure is crucial. This technique allows the cutter to effectively remove any burrs or sharp edges without excessively grinding or damaging the material. Light pressure ensures better control of the cutter, reducing the risk of overcutting and altering the original hole geometry. It also helps to prevent heat buildup, which could lead to material degradation or warping, especially in sensitive applications. This method allows for a clean finish, which is important in aerospace assembly where precision is key.
