Sewing machines Because we have left several units apart, it is an additional repeat purchase. The tip width is 5 mm and the error is not stretched. This is pretty rare type, it can not be substituted by others for other uses.
Used for handwheel nipple turning. D-640-100 is conveniently made to rotate the nipple from the hole opened in the wheel because it is made in parallel with the diameter unchanged from the shaft to the tip. Surface treatment is also satin and elegant, the part of the handle is a little small, it is unsuitable for applications which force is forcibly turned by applying force. I think it will be positioned one above the precision screwdriver.
