Hello, I'm looking to cut an internal thread inside of a 1/4" hose tail so I can place a very small camping stove jet in the hose tail. I know I need to buy a 4.5 mm metric taper tap and a holder but where would be the best place to buy one of these. I was thinking msdicount.com but I wasn't able to find a holder for it. Plus they are trying to charge me $27 just for the tap itself. Any helpful information would be greatly appreciated. Thanks.
