Serger 80/12 Needles 5-pk ELX705-SUKCF80

Designed for use in electronic multi-purpose sergers that do the overlock, cover, safety, and mock safety stitches.
Machines should specifiy the ELX705 system - not suitable for use in normal home sewing & embroidery machines.
Chrome Finish, Ball Point (SUK) Size 80/12 and 5 needles per pack.

Here's how ELX705 needles vary from home sewing needles.
*Needles have a groove on the front side and back side of the blades to reduce skipped stitches.
*The second long groove is necessary to create chain stitches like overlock and coverlock stitches.
*They have increased strength due to a reinforced blade leading to less breakage and straighter stitches

How often do I need to change the needle?
A good rule to follow is every 3 to 5 hours of sewing, which is probably after every quilt is finished.
