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 RecommendJust bought 80 v string trimmer, Why is it so difficult, if not near impossible to wind new line on to spool. Can the line be wound with spool removed from head?
Poor quality
Would Not RecommendJust a heads up if you’re looking for a quality battery powered lawn equipment with readily available replacement parts DO NOT BUY KOBALT! The pressure washer is garbage no matter the setting (I get better results with a standard garden hose) the weed eater I can never find the correct or compatible parts. But the blower is good for the garage, I wouldn’t take it much further than that. The only thing that hasn’t given me any issues is the inflator fortunately it’s rarely used. I personally woul...

Don't buy
Would Not RecommendLowes doesn't stock replacement parts for Kobalt trimmers. Not worth the risk of owning, in my opinion. I own the KST 130X - and I'm out of luck. Won't buy again. Attention: Please don't respond something about calling the team at the 800#. I did that.

Check your Model # 623439 or 670250 it was an ex
Would RecommendSo, I was concerned with all the negative reviews, but when I saw one stating the model #'s I gave it a try. To my surprise it was in stock and said it would be here in 7 days, but it was at the store the next day, so my experience was better than expected. As for changing it out if you position it as it would be while weed eating and look on top of the trimmer gear box on the right side, you'll see a hole stich a drill bit in it while rotating the head once it locks turn head clockwise and it s...
Diabolocal? Maybe not
Would Not RecommendWhen the string broke on my kobalt weed wacker I cringed fearing it might not to easy to replace - but when I actually went through the uphill battle to figure out the replacement part and then actually tried to replace it, I thought perhaps it was engineered with a diabolical intent to ruin my day - when I tried to float this view of myself as victim of a nefarious plot past my wife, she rolled her eyes, and with both laughed - okay so it probably wasn't diabolical - but come on, really - if yo...

Pleasantly surprised
It showed up quicker than expected and fit perfectly. I waited to write a review until I had a chance to use it, but so far... it's working great!

This fits the 80v Kobalt Trimmer
Would RecommendI am not sure why the other reviews state that this does not fit the Kobalt 80v Trimmer, unless there is a different model number for the trimmer. in the description, it lists the two model numbers this is compatible with. This fits it perfectly. I do wish they had these in the store, but since they have to be ordered from Lowes, just make sure you order two so you can be ahead. Other than that, take off the top part, insert it into your trimmer, and enjoy.

New trimmer head will not fit older trimmers.
Would Not RecommendThe trimmer head would not fit on my Kobalt 80 volt trimmer. The threads were slightly different from my trimmer and I could not make it thread on.
