Multiple Choice

An 18 pitch hacksaw blade is satisfactory for general hacksawing.

Explanation:
An 18-teeth-per-inch blade is a versatile, general-purpose choice for metal cutting because tooth density affects both speed and finish. Fewer teeth cut faster but rougher, while more teeth cut smoother but more slowly. An 18 TPI blade provides the right balance for typical hacksawing tasks, working well on common metals like mild steel, iron, brass, and aluminum without bogging down or leaving a very rough edge. For very soft or very hard materials, or when a finer finish is needed, different pitches can be chosen, but for general hacksawing this pitch is satisfactory.
