Features Made of high quality oxygen-free copper which is of fast conductance and heat resistance up to 480℃ for use. Applicable to 936, 937 soldering station and so on with its pointed end shaped like a needle that is suitable for crafted workmanship, for example, fit the alarm fob of a car, like micro switch had popped off the small circuit board and the contacts for the micro switch are smaller than micro (smaller than a pin head). Soldering in a narrow space, revising the tin bridge emerging from chip soldering. It makes soldering those delicate, tighter connections much, much easier.If with appropriate use of iron tip, its lifetime can reach over 20000 welding joints. It has advantage of long life lasting and not easily oxidize, easy to install and use. It has high safety and stable performance. Quite easy to take and clean. Use the sponge to polish the surface. Please do not leave them exposed to the air, better wrap them with tin. Description:These iron tips are electroplated Iron which protect them from oxidation, characterizedby heat-resistant up to 480 ℃ and lifetime over 20000 welding joints with appropriate use. As thepoint is very sharp, it fits for crafted workmanship, for example,  about car problem, once microswitch had popped off the small circuit board, you found that the contacts for the micro switch issmaller than micro (smaller than a pin head),  or soldering in a narrow space also for revising thetin bridge emerging from chip soldering. How about getting this set and making your solderingwork easier? Specification:Material: CopperColor: SilverPlating: Iron (Finish)Outer Diameter: approx. 6.7mm / 0.26"Inner Diameter: approx. 4.0mm / 0.16"Length: approx. 43cm / 16.93"Package Weight: approx. 47gModel: 900M-T-IApplicable to: 936, 937, etc.  Temperature Range: 200-480℃Quantity: 10pcs / bagFor storing used iron tipsUse sponge to clean iron tip.Wrap them with tin solder.Turn off the power supply and wait until they cool.Put iron pen on the iron shelve.
