The cross fibers which constitute the knit or loosely woven materials are relatively far apart as compared to those in tightly woven material. When a needle with a standard "sharp" point encounters one of those fibers in penetrating the fabric, it cuts right through the fiber. This creates a hole in the fabric. The Ball Point needle pushes aside the fiber it encounters in penetration and thereby avoids making a damaging hole in the fabric. These are round shank needles for industrial overlock machines. Will not work on home portable overlock machines. Schmetz B-27 Ball-Point needles are available in following sizes. Please select your size. Singer Size 9 (Metric Size 65) Singer Size 10 (Metric Size 70) Singer Size 11 (Metric Size 75) Singer Size 12 (Metric Size 80) Singer Size 14 (Metric Size 90) Singer Size 16 (Metric Size 100) Singer Size 18 (Metric Size 110) Lower size numbers are narrower or thinner needles used for lighter materials. Higher size numbers indicate a needle of thicker diameter, used for heavier materials. Match your needle system to your machine, then the size of the needle to the product you are sewing.
