When chamfering titanium, what is the recommended RPM of the drill motor?

When chamfering titanium, selecting the appropriate RPM for the drill motor is crucial due to the material's unique properties. Titanium is known for its strength and low thermal conductivity, which can lead to excessive heat generation during machining operations if the speed is too high.

The recommended RPM of 300 is often favored because it strikes a balance between providing sufficient cutting speed and minimizing heat buildup. This RPM allows for effective material removal while reducing the risk of work hardening or damaging the tool and the workpiece. Machining at this speed helps maintain tool life and ensures a clean chamfer without excessive wear or distortion of the titanium, which can occur if the RPM is too high.

The other options likely either exceed the safe limits for titanium machining or fall short of the necessary cut efficiency. Therefore, 300 RPM aligns with best practices for optimizing machining performance when working with titanium materials.
