Discuss Honeywell VA8200A001 TVR Service Tool Hire in the Plumbing Tools area at PlumbersForums.net
They are Honeywell VT15BG, I have relooked at the IMI Hydronics Insert Tool and it works with a 19mm Hex head which is the same as I have and at a much more competitive price.What brand of valves do you have?
Some valve manufacturers have their own tools for removing the valve insert on a pressurized system.
Some are quite reasonably priced too.
