I never know when to use small needle, micro needle and nano needle. For this needle I decided to use micro needle tip. Many of our competitors show you pictures with their products next to a coin so you can easily compare how small they are. We on the other hand put the needle right on top and focused in so you can see if you can guess what type of coin it is.
This particular micro needle tip is going to be welded on to a .013″ stainless steel tube with a hole in the tube for drainage or for drug emission. The .0057″ shoulder helps guide the tip into the tube which has an ID of .006″. The .004″ step is used as a guide to know where to cut off the shoulder. The tip is 25 degrees sharp. The most difficult part of this piece is connecting the tip to the tube due to the small size of both. Grinding micro parts is the easiest part of the process.
