DB-K5 CS: The Cool-Sew finish was developed to alleviate needle problems resulting from the following situations:
1) Heat Buildup in penetration of synthetic, chemically treated, or very dense materials
2) Materials or residue sticking to needle surface or in eye
3) Excessive sewing thread breakage due to friction in the needle eye

The COOL-SEW finish needle’s surfaces, even in the eye, are resistant to sticking. Its non-stick finish has a very low friction coefficient which prevents excessive heat buildup and its resulting problems. Few, if any, materials stick to the surfaces of Cool-Sew needles.

When COOL-SEW needles are used under conditions described above you can expect neater stitches, less sewing thread breakage, less puckered stitches, less downtime, less defects, and increased productivity.

COOL-SEW needles are ideal for sewing through vinyl, synthetics, chemically treated materials, glued materials, rubberized goods, nylon, foam, dense materials, and with synthetic threads.

Embroidery needles on this page are round shank needles
for commercial/industrial embroidery machines only.

This embroidery needle is designed especially for industrial /commercial embroidery machines such as Tajima, SWF, Barudan, etc. The DB-K5 needle has a one size larger eye than that found in a regular needle. Unlike sewing thread used for general apparel sewing, embroidery threads are "fluffier" and have less tensile strength. A larger needle eye, without increased blade diameter, allows the embroidery thread to pass easily through the needle's eye without fraying or snapping
Specifications

icon The most popular needle, the Universal, has an eye that is 40% the width of the blade. Really! There are three other needles with larger eyes, the Embroidery and even more pronounced is the elongated eye of the Metallic and Topstitch needles. Now what does a larger eye mean? There is less friction on the thread as it passes through the eye. Ever sew with a thread that breaks or tends to shred? Guess what, use a needle with a larger eye. If you have old thread or maybe a poor quality thread, use a needle with a larger eye. The thread and needle work hard and fast. Help them out when you can with a larger eye.
