Which toolholder holds up to four cutting tools for use in a single operation?

• A. Station toolholder
• B. Turret
• C. Tool post
• D. Indexable holder

Answer: (A)

Having several tools ready at once is what a station toolholder enables by providing multiple tool stations in one holder. Each station can hold a cutting tool, so you can mount up to four tools and index through them in a single operation, eliminating extra tool changes and keeping the workpiece stationary for efficiency. A tool post generally holds only one tool at a time, so it can’t supply a sequence of tools without manual changes. An indexable holder is used for a single tool that carries replaceable inserts, not for mounting several tools simultaneously. A turret houses multiple tools, but the specific phrasing here points to the toolholder with fixed stations that accommodate several tools. Therefore, the station toolholder best fits the requirement.
