Kester 24-6337-0027 Solder Roll, Core Size 66, 63/37 Alloy, 0.031 Diameter

Its the standard for 44 Rosin Core solder. Works exactly as advertised, and the hexagonal box is handy. I recommend it.

Great Product

This is incomparably better than the cheap solder that comes with cheap Chinese soldering irons. Soldering with this is easy even for a beginner like myself. I just finished building a simple Pixie 4.3 radio kit using this solder and it couldnt have been any easier. I also used it to solder some powerpole connectors and it worked great.

I used the solder to connect a wire in a flashlight that had broke loose. The flashlight is working now.

Wets surfaces well, flows nicely, generous flux. Its Kester just as expected

What can you say about solder. It melts.

Ive always had a hard time soldering. I have tried many varieties of solder and flux as well as different irons/guns. I just figured thats how it was. I just used this Kester 63/37 today along with some new Rubyfluid soldering paste and wow, night and day difference. Just finished repairing several broken wires in a automotive wiring harness and I actually enjoyed the soldering work this time. This solder melts quick and flows nice. Its expensive but worth every penny.

worked fine for soldering to add mounting headers to Sparcfun XBee breakout boards. Wanted even smaller diameter but this worked OK.

Toss that Radio Shack crap away and buy this. You will notice a difference right away. I do a 1000 solder joints a day and this solder helps eliminate those frustrating moments when you solders doesnt want to flow consistently. Very happy with this product and it is now my go to solder.

Great product. I think this solder cant be beat.
