The Pro Hot Knife Butane Tip has a diameter of 1mm or 0.039in.

Our Pro tips are iron-chrome plated to withstand long periods of soldering time. More specifically, the copper shell is iron plated to resist erosion, chrome plated to resist corrosion and tinned to provide efficient heat transfer. These processes provide maximum tip life for extended usages.

NOTE: This tip will not work in the Pro 120.
