VEVOR Copper Pipe Bender, 7 Colorful Dies 1/4-7/8 inch 90 Degrees Forward and Reverse Bending, 6-22 mm for Copper & Aluminum Tubes with Reverse Bend Attachment

Does it kink copper tubes

Is this tool designed to accommodate Imperial more than Metric or does it fit Metric perfectly? The reason I'm asking is that i just had to return a mini bender back to Amazon because the metric sizes did not fit in the shaper correctly because 3/8" is not actually 10mm but 9.525mm. I'm more interested in using the tool with Metric pipes. Imperial is a thing of the past. So basically I need the tool to be a perfect fit for Metric. Thank You.

WILL THIS BEND 15 AND 22MM WITHOUT KINKS
