What RPM is required for the 90-degree drill motor when enlarging holes for the -10 fasteners?

The required RPM for a 90-degree drill motor when enlarging holes for -10 fasteners is 700 RPM. This specification is essential to ensure that the drilling process is effective and can accommodate the size and material of the fasteners being used.

Selecting the correct RPM is crucial as it affects the cutting speed and the quality of the hole being drilled. If the RPM is too low, the drill may not efficiently cut through the material, potentially leading to burrs or incomplete holes. Conversely, if the RPM is too high, there is a risk of overheating the drill bit or damaging the surrounding material, which could compromise the integrity of the assembly.

Using 700 RPM strikes the right balance between providing sufficient cutting action while minimizing the risks associated with high-speed drilling. This RPM setting helps maintain control over the drilling operation, ensuring that the holes are enlarged to the precise specifications necessary for installation of the -10 fasteners.
