What type of files are used to file acute internal angles and to clear out square corners?

Triangular files are tailored for getting into tight interior angles. Their pointed tip and three cutting faces let you approach acute angles directly and trim material from both sides of the corner, producing a clean intersection. That same geometry also helps you work square corners: you can place the tip into the corner and use the sides to smooth and remove material without enlarging the opening. Round files are better for holes and curves, while square files are best for flattening or shaping true square corners but don’t reach acute internal angles as effectively. Rifling files are specialized for rifled grooves and aren’t the general-purpose choice here.
