[Model] 900M-TI Outer Diameter: Approx. 6.7mm / 0.26" Inner Diameter: Approx. 4.0mm / 0.16" Length: Approx. 43 cm / 16.93 " [ [Features] This tip has the advantage of long service life and does not rust easily, it is easy to install and use. [ [Applicable] This tip is applicable to the soldering station 936, 937 and so on with its needle-shaped pointed end which is suitable for handicraft making, for example, it is attached to the alarm control as yes, the microswitch would have detached from the small circuit board and the contacts of the microswitch are smaller than the micros. Product Description These iron tips are made of electrolytic iron and nickel which protect them from oxidation, characterized heat resistant up to 480C and a Lifespan of more than 20,000 solder joints with proper use. As the point is very sharp, it is suitable for craft finishing, for example, car problem, once micro the switch had jumped off the small circuit board, you found that the contacts of the micro switch are smaller than micro (smaller than a pinhead), or soldering in a narrow space also to revise the tin bridge coming out of the solder to the chip. How about getting this set and making your soldering work more easily?
