Both tools have a large and a small caliber core puller. Both 8mm (larger) removal tools were bent when attempting to remove the valve from the A/C low pressure drain port. A larger tool with a red plastic handle turned the metal inside the handle on the first try. Both tools are made of fairly soft metal, so skip this set for its tools. I was hoping it would be "good enough" to open the valve, but it didn't. Haven't had a chance to test the valves myself, maybe they're fine.
