Fits the Hakko FX-601 model only.
Available in 3/16" or 1/4" tip widths.
The 3/16" tip is the standard tip that comes with the Hakko FX-601 temperature controlled soldering iron.
The 1/4" tip is slightly wider for when more heat coverage is desired.
Great for making smooth solder seams, or for soldering lead and metal cames.
