Frequently asked questions

What does a tool room operator do?

A tool room operator makes and repairs tooling in the tool room. They run surface grinders, milling machines, wire cut and EDM to machine die and mould parts to close tolerance, help assemble and fit tools, and repair worn parts. They keep dies and moulds ready so production lines are not stopped for tool problems.

What is the difference between a tool room operator and a tool room engineer?

A tool room operator machines and fits tool parts on tool room machines from drawings. A tool room engineer designs the tools, plans their manufacture, proves them out on the machine and decides repair strategy. The operator executes the making and repair, while the engineer owns the design and the schedule.

What qualifications do you need to be a tool room operator?

Most tool room operators hold an ITI in the tool and die or machinist trade, and a tool making course from an institute such as NTTF is a strong advantage. Employers look for the ability to hold fine tolerances on grinders, wire cut and EDM, read tool drawings with GD and T, and fit dies and moulds accurately.
