gtwister09 Report post Posted February 4, 2011 Has anyone tried the titanium nitride (TiN) Perfect Durability needles from Organ? Are they a cost effective alternative? Do they hold up as long as claimed? Any insight and information would be greatly appreciated. Art, Barra, Steve, Wiz.... you guys can all weigh in here as well as well as anyone else who may have tried them. I figured Steve may have some information since he deals with them. I do have all the technical corporate information but was looking for actual user thoughts. Thanks again for any insight. Regards, Ben Quote Share this post Link to post Share on other sites
Art Report post Posted February 4, 2011 Hi Ben, I use TRI or Diamond points and haven't seen these listed, only fabric systems. I also haven't seen any studies on them. I use mostly Schmetz and Groz needles, and didn't find the Ti coating in the catalog. Things change rather slowly in the sewing business, Ti coatings have been around for decades and they are just coming into use for needles.

gtwister09 Report post Posted February 4, 2011 Art, Thanks! I saw the TiN coating on a 794SD needle made by Organ. I tend towards the Schmetz first and then the Groz Beckert needles as well. I don't know if I can say this is purely scientific but over time I would have to say that the Schmetz seems to be a harder needle (tend to break them more) versus the Organs which tend to bend. Of course I can only say that was over about 30 Organ needles versus a whole lot more Schmetz. It may have just been the batch of needles but that was just my observation of the two needle companies. Your mileage may vary. I happened to see them on the CTSUSA site. CTSUSA SD1 PD Needle I have included a PDF from Organ's Technical Specification downloads that shows the TiN thickness on the needle profile, abrasion tests and some other information. PD_e.pdf Like you I have seen the TiN coating on cutters, drill bitss and so many other cutter related items. On the TiN drills they tend to be throwaways because the bits themselves seem to be so much softer than HSS bits. Out of the 3 sets of drill bits that I have used, two of them couldn't be salvaged by the Drill Doctor after they became dull ( disappointing to say the least).

Art Report post Posted February 4, 2011 Hi Ben, I too have found the Organ needles a little bendy, I have not used enough of them to know if I like it or not, heck, for the most part a needle is a needle. I do prefer the Groz for the Pfaff and the Singer 31s (134D), and either Schmetz or Groz for everything else. The Groz are a tad more expensive. Other than that, I can't say I give them a lot of thought. Art Art, Thanks! I saw the TiN coating on a 794SD needle made by Organ.

CampbellRandall Report post Posted February 4, 2011 My 2 cents - The coating is more applicable in high speed sewing or abrasive materials. It makes the surface harder and reduces friction, but it will not increase the strength (flex resistance) of the needle. TiN coated tools usually have a coating 2-4 microns thick, which is a fraction of a thousandths of an inch. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted February 12, 2011 (edited) I was asked if I personally use or have an opinion about the titanium coated needles. I don't particularly go out of my way to buy them, unless that it all that is available in a certain size I need quickly. I sew at very slow speeds on thick leather and would not benefit much from the heat reduction treatment on these needles. Any jobs that would generate a lot of heat probably use thicker thread and needles than are not practical on my walking foot machine. Those are sewn on my 800 stitch per minute Union Lockstitch Machine, where needle heat is not an issue. I do not have a 441 or a 205 clone machine at this time, so I cannot answer questions about series 7x3 or 7x4 needles. If I should decide to buy some titanium coated series 190 needles, for my modified National walking foot machine, I will be glad to post my observations, should I have any.
