A tool bit ground to cut machine steel can machine all types of metals.

A tool bit ground to cut machine steel can machine all types of metals.

• A. True
• B. False
• C. Depends on the grind
• D. Only for steel and iron

Answer: (A)

A tool bit that’s ground to cut machine steel is built with a geometry that delivers a reliable cutting action and edge life suitable for metal removal. That same edge, when used with the right cutting conditions—appropriate speed (RPM), feed rate, and cooling or lubrication—can machine a variety of metals, not just steel. In basic machining practice, the cutting edge produced for steel provides enough versatility to work on many different workpiece materials, even though each metal may respond differently and some situations may call for different tool materials or grinding to optimize performance. So the statement holds as a practical general rule: the bit can be used to machine all types of metals with the proper settings.
