Kester 24-6040-0053 Solder Roll, 66 Core Size, 0.050 Diameter

Kester is Kester, the premier name in solder. I occasionally use some off-brand solder and in most cases it works fine. However if you want a consistent outcome, use Kester. I bought this because it was Kester brand AND a good price.

Hello, its solder.

The product itself is fine if you dont need recent production. If youre buying it chances are you know what youre buying and dont need a review for that. I bought 2 different rolls from this seller (different diameters). The first one the cardboard box was a bit beat up. On both the place where the date of manufacture usually is was peeled off. They put clear packaging tape over the top of the entire thing which makes it less noticeable. If you didnt know there was supposed to be a date of manufacture there you would probably never know the difference. According to Kesters own website the shelf life for flux cored solders is 2 or 3 years (depending on formulation) which is why they put a date of manufacture on them. For what I do it really doesnt matter. But if youre buying them for an application where that is important you dont want to buy from Amazon/this seller. In the future Ill just spend more $$$ and go with Digi-Key so I know what Im getting hasnt been laying around for a decade. It seems disingenuous to sell something as new which has a shelf life and then to remove the information from the package which states when it was made.

What can go wrong with solder?

Its rosin core 60/40 solder. it melts, sticks to wires and goes solid again and there is enough here to cover my needs for the next decade or so. What more can you ask of solder.

Kester is a solid product. Theres not really much to say...my Grandfather used it on the laser boards when he worked for TI and I use it on wire repair in automotive.

cant go wrong with Kester solder. this ones a bit thick but i have other sizes. Still at a decent price.

Very good solder! Worth every penny. Flows so much better than the less expensive stuff I’ve purchased previously. I’ve had no problems at all using this brand. Highly recommend

Excellent quality as expected from Kester.
