Ratings & Reviews for Kobalt Universal Fit 0.080-in Line String Trimmer Replacement Head
Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers report significant frustration with replacement part compatibility, with many finding spools and trimmer heads do not fit their models despite universal labeling. Several note parts are unavailable in-store and online, forcing them to abandon the system entirely. Threading and design inconsistencies across generations render worn components irreplaceable. However, a minority report successful installations and praise improved spool design and durability. Those who succeeded often required third-party research and tools. Overall, incompatibility and parts scarcity overshadow positive experiences for most users.

The base of this head does not fit on my Kobalt string trimmer. I is molded to a different shape and the nut is threaded differently. I'm guessing my model is older and the base plate was factory installed, not easy to remove. When I finally got it off, the new one would not screw on to the threaded drive shaft.

Doesn't fit
Would Not RecommendThe old trimmer head is no good and had to be replaced. This replacement part does not have the correct threads to fit the shaft on the motor. Completely useless.

Wrong way thread for my older 80 volt Kobalt
Would Not RecommendWrong way thread for my older 80 volt Kobalt trimmer. I am 70 years old and have had two of the trimmers for about 4 or 5 years now. I was disappointed to be forced to buy a new 80 volt trimmer only because the thread was wrong, but product indicated it was for an 80 volt Kobalt trimmer. No model numbers were noted on the the product information.

Replacement trim head for Kobalt model KST 1680-06
Would Not RecommendI contacted Lowes about the inability to find a Kobalt weed trimmer string replacement for their model KST 1680-06 weed trimmer. I had been trying on line and visited a Lowes store 3 times without success. I finally phoned the Lowes Kobalt facility and was told they would send me the correct part for $38.38 including shipping. When the part arrived it was evident that it was not a direct replacement, so I called back to complain and after back and forth discussion with them, they admitted it was...

Disappointed
Would RecommendIt says universal fit when it was ordered, but when the box came in, it only fit the Kobalt 80 V and of course mine 40 V and it did not fit. So I returned it. If you’re sale the Kobalt products you should have replacement parts available and there are none. Of course my five-year warranty ran out a month ago so now I have a pile of junk.

Not Universal

Did not fit
Would Not RecommendI needed replacement head for a 24-volt Kobalt string trimmer. This item came up as the result in the search on the Lowe’s website. Once received, the box states 80-volt. This item is too big for a 24-volt trimmer. Apparently, a replacement does not exist for a 24-volt Kobalt string trimmer. Disappointed that Lowe’s doesn’t state that outright. And disappointed that replacement parts are not carried for all Kobalt battery equipment. My only recourse is to buy a new string trimmer. Will l...
