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.

Would Not RecommendI have the 80v Kobalt string trimmer and love it. Unfortunately the original spool never really released the line upon bumping so I had been looking to replace the spool assembly eventually. Well I finally got around to it today and purchased this replacement spool earlier today at my local Lowe's (surprisingly they had two in stock!). The first thing I noticed upon opening the box was that the design was very different from the OEM spool. This replacement spool doesn't have the fins at the bott...
Bolt on problems with threads
Could not get the threads to work on my weed eater. I had to rethread the bolt then made it work. Can't tell how long it will last

Works well but no directions
Would RecommendThis works well for the Kobalt 80V string trimmer. I am deducting a star because there are NO instructions. Go on youtube and you can find out how to remove the old trimmer head (you need a hex key tool). Also, for some reasons this trimmer contains two separate pieces of string, which stops working as you wear it down. You have to remove one of them...this trimmer works only when loaded with a single piece of string.

Kobalt V80
Would Not RecommendI have used my Kobalt v80 very little and now need a replacement head and cannot find a replacement head from any one else because when mine was assembled the threads were striped. And now Kobalt doesn't make any more of these... The trimmer works good, but the head has always been junk.

Does not fit
Would Not RecommendWhile I enjoyed the 80v max trimmer because I can hear my kids while I’m in the yard, I’ll be going back to stihl. It took for ever to find a replacement head, which ic close to the original, but not the same. To me that shouldn’t be labeled as a “direct replacement” for the 80v max. Finally got it in just to find out it doesn’t fit. It will work if you trim ⅛ inch off the spacer under the spool, then press the nut out of the old spool, and press it into the new one. Should’ve been a 20 minute j...

can't find replacement spools for 40 volt trimmer
Would Recommendwhy does the lowes web site show they have kobalt replacement spools but when you go they say they have never carried them. i have wasted my time on 2 trips to lowes dickson, and on internet trying to find. i bought my trimmer in march of 2021 and love the trimmer but you would think the spool and bump knob would last longer. will now have to pay shipping from other lowes location.

The Kobalt trimmer is nice, but if you need a part for it you can't find it in Lowes stores. Called the Kobalt company and they didn't even have it. Will not buy another one.

No Instructions
Would Not RecommendHow am I supposed to install this? It does not come with any instructions. I may be stupid, but it is not intuitive as to how to get the old one off to install the new one.

80V Trimmer Spool
Would Not RecommendVery pricey for plastic. Design was slightly different than original, therefore I had to use a combination of old and new parts. Wish I could have bought only the part that you tap to feed trimmer line. This comes as an assembled unit, it would be more convenient if components were sold separately and making replacement less expensive. I couldn't find Kobalt parts elsewhere so they have you over a barrel after purchasing an expensive trimmer.

Not sure what the fuss is about...
Would RecommendYeah, my store didn't have in stock, so I ordered it online. It took ONE week to arrive - big whoop. One spool lasts me two years, so this isn't a huge expense. Trimmer back in business!
Concerned about other reviews, happy with result
Would RecommendAfter reading the other reviews, I was concerned that this would not fit my 80v trimmer. It seems that the thread changed at some point causing a fitment issue for others. I went to the local store last night to get the Shakespeare head that can be adapted to any trimmer and found this on the shelf as a cancelled online order. I figured I would give this a shot because OEM direct fit would be easier in the long run. Sure enough, it fit. I purchased my 80v trimmer (623439) back in May 2016, ...
