15x1 ST BP / HAx1 ST / 705H-E PD. This is a special version of the 15x1 for embroidery and decorative stitching. It is made to higher standards for longer life. It has an over sized eye to reduce stress and tension on the thread. It also accommodates metallic threads or heavier top stitching threads and makes needle threading easier. PD (Perfect Durability) needles have a titanium-nitride ceramic finish which makes them more wear-resistant than other needles. When embroidering large stitch patterns or penetrating very abrasive, dense or tough materials the needle points and surface will maintain its original shape and dimensions 3 to 5 times longer. PD needles points will not wear down as fast as chromium plated needle points. The use of PD needles gives you longer needle life, fewer defects due to dulled needle point and increased productivity.
Lasts 5 times longer than chrome plated needles!
It is available in sharp or ball point, also available without the PD/titanium finish.
