This needle bar is designed specifically for old-school coil and rotary machines. This bar is for attaching your own custom needle, so it does not come with a pre-made needle. Also, please note that it is not compatible with the type of machine that installs cartridge needles. There are two types of bar tips: round for liners and flat for shedders and colour packing. The bars are 123 mm long and made of high-quality stainless steel.
