A high quality, long lasting Titanium-nitride coated, topstitch sewing machine needle. Stay sharp for 40-60 hours. Topstitch needles feature a deeper and wider groove and an elongated eye. Pack of 5 sewing machine needles.
The first Titanium coated Topstitch needle for home sewing machines. These needles have a larger eye, the Superior needle has an eye almost twice the length of a standard universal sewing machine needle. It also has a deeper grove up the shaft which protects the thread whilst stitching. This makes it ideal for metallic threads and it will easily take a thicker thread. The Titanium-nitride coating gives advanced abrasion resistance which stops threads shredding. It also gives a resistance to wear on the point of the needle making it sharp for much longer. It is recommended that you should change your needle for every project or every 8 hours of stitching, these needles will stay sharp for 40-60 hours.
The BERNINA Blog says:
"Superior Titanium-coated Topstitchneedles are machine needles with a thin layer of Titanium-nitride, which make the needle stronger in terms of tensile strenght. It keeps the point sharper for a longer time. Titanium-nitride is a very tough substance with excellent abrasion resistance. The needles of Superior come in 4 different sizes, of which the most used are 70/10 (for thin threads), 80/12 (all medium size threads) and 90/14 (for all threads, even thicker ones and metallic threads). These needles last longer than regular needles, up to 5 or 8 times. They are not cheap, but worth every penny you are spending on them."
