🔍 Key Concepts

• Relative hardness of metals listed: cast iron, high carbon steel, aluminum, copper • Effect of material hardness on recommended drilling speed (surface feet per minute – SFM) • How heat generation and tool wear change with drilling speed in softer vs harder metals

💭 Think About

• Arrange the four materials from softest to hardest based on typical engineering knowledge • Think about which materials allow higher spindle speeds without quickly dulling the drill bit • Consider which material is commonly drilled very quickly in machine shops without using special cutting tools

✅ Before You Answer

• Verify which of the four is generally considered soft and easy to machine • Check standard machining tables for recommended drilling speeds (SFM) for each material • Confirm that the correct choice will have the highest recommended cutting speed among the options
