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

It flows well, the flux does a good job, and a giant roll will last through many DIY projects.

Good brand with good performance. Cant go wrong with this product.

Been using this solder type for 50 years. EXCELLENT flow and boding. The flux is also easy to remove.

WOW! I never realized how wrong I was soldering before. Absolutely perfect for my Amateur Radio gear and other small electronics products/kits. Ive built small digital clocks to full radios with this and its amazing stuff! Worth every penny!

My favorite

Kester has always been great solder. I have always used lead based because that is all we could buy way back then. I suppose I should try not/lead sometime but why change when this works super.

Just as advertised. Prompt delivery and quality product.

On the stand it stands perfectly

I have been an amateur bench tech for 45 years. Every time I buy other brands solder I regret it. Kester solder with core size 66 in a 63/37 alloy and 0.031 diameter is the best all-around solder to keep on your bench. This is Kester part number 24-6337-0027. At a recent maker event, I would see people struggle with the solder they brought. I would cut off a foot of solder from my roll and they immediately noticed the difference. If you buy a roll, you will not regret it.

Excellent! Exact product I was looking for and Amazon has it at the best price and eligible for shipping. Have purchased multiple times and will continue to purchase from Amazon.
