Kobalt 40-Volt Max 15-in Straight Alternatives: 6 Similar Picks Compared
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You are looking for kobalt 40 volt max 15 in straight alternatives because your needs may have changed. The original Kobalt trimmer offers a 15-inch cutting swath and fits into the 40V ecosystem. It is a tool-only unit, which is practical if you already own compatible batteries. The straight shaft design allows for precise control in tight spaces.
However, you might prefer a different voltage, a wider cut, or a brushless motor for better efficiency. Some users need a lighter weight or a 13-inch width for easier handling. Others may want 56V power or a 16-inch swath for faster clearing. We selected these picks because their specifications overlap with the original Kobalt model. Each option shares key traits like cordless power and similar cutting widths. This list helps you compare specs directly to find the best fit for your yard.
Our top pick: Kobalt 40V Max 15-Inch Straight Shaft Trimmer.
How these alternatives compare
Makita 40V max Brushless 15" String Trimmer
The Makita 40V XGT model shares the 15-inch cutting width but uses a brushless motor for higher torque. This makes it better for thick weeds than the Kobalt unit. It requires Makita 40V batteries, so it only fits if you already own that ecosystem. The shaft length is significantly longer at 72.4 inches, which changes the handling balance. You get variable RPM control for precision. If you need more power for dense vegetation and have Makita batteries, this is a strong upgrade over the standard Kobalt string trimmer.
EGO Power+ 15-Inch Cordless String Trimmer
The EGO Power+ unit steps up to a 56V platform with a 2.5 Ah battery capacity. It offers a 15-inch cut like the Kobalt but delivers more voltage for sustained performance. The brushless motor and fast charging capability are key advantages. It weighs 7.4 pounds, which is slightly heavier than some competitors. This model suits users who want faster charging times and higher power output. If you are not locked into the 40V ecosystem, the EGO provides a premium experience with better runtime management for small to medium yards.
Worx 20V 15-Inch Cordless String Trimmer
The WORX 20V model drops the voltage to 20V but keeps the 15-inch cutting width. It is a tool-only unit, just like the Kobalt. The weight is 6.62 pounds, making it lighter than the Kobalt for easier handling in small yards. It uses a brushless motor for efficiency. This choice is best for homeowners with existing 20V batteries who need a lightweight tool. It gives up some power for reduced weight and cost. If your yard is small and you prefer a lighter trimmer, this WORX option is a practical alternative to the heavier 40V Kobalt.
Makita 18V Brushless 13-Inch String Trimmer
The Makita 18V model reduces the cutting width to 13 inches. It uses an 18V LXT battery system, which is different from the Kobalt 40V platform. The weight is 9.23 pounds, which is heavier than the WORX but comparable to other 18V tools. The brushless motor ensures efficient power delivery. This trimmer is ideal for users who prioritize precise control and lighter cutting tasks. If you do not need the full 15-inch swath and already have Makita 18V batteries, this is a focused choice for detailed trimming work.
Greenworks 40V 16-Inch Brushless String Trimmer
The Greenworks 40V model increases the cutting width to 16 inches. It shares the 40V voltage with the Kobalt but features a brushless motor. The weight is 11.3 pounds, which is significantly heavier than the Kobalt. This added weight may affect handling for some users. The wider cut allows you to clear more grass per pass. It is the best option if you want a wider swath and already own Greenworks 40V batteries. If you prioritize coverage speed over lightweight handling, this Greenworks trimmer offers a clear advantage in cutting width.
Makita 18V Brushless Couple Shaft Power Head
The Makita 18V Couple Shaft Power Head is a versatile base unit rather than a complete trimmer. It does not have a fixed cutting width or shaft. It uses an 18V LXT battery and features a brushless motor. The weight is 8.55 pounds. This unit allows you to swap attachments for different tasks. It is best for Makita users who want a multi-tool system. If you need flexibility to switch between trimmers, edgers, or blowers, this power head offers more utility than a dedicated Kobalt string trimmer. It requires you to buy attachments separately.

Frequently asked questions
Can I use my existing Kobalt batteries with these alternatives?
No. These alternatives belong to different battery ecosystems. The Makita 40V and EGO 56V models require their own specific batteries. The Worx and Greenworks units use 20V and 40V platforms respectively. You must purchase compatible batteries for each brand. Only tools within the same brand family share battery compatibility.
Which trimmer offers the widest cutting width?
The Greenworks 40V model offers the widest cut at 16 inches. This exceeds the 15-inch width found on the Kobalt, Makita, EGO, and Worx options. A wider cut reduces the time needed to clear grass. It is ideal for larger areas where efficiency matters.
Is there a lighter option for small yards?
The Worx 20V model weighs 6.62 pounds. This is the lightest unit in the list. It is designed for small yards and lightweight handling. The Makita 13-inch model is heavier at 9.23 pounds. Choose the Worx if weight is your primary concern.
Do these models feature brushless motors?
Most options include brushless motors for efficiency. The Makita 40V, EGO, Worx, Makita 18V, and Greenworks models all use brushless technology. The Kobalt 15-inch model does not specify a brushless motor in its attributes. Brushless motors typically offer longer runtime and durability.
Which model is best for thick weeds?
The Makita 40V XGT model is built for high torque. Its brushless motor and variable RPM control handle thick weeds effectively. The EGO 56V model also provides strong power for tough jobs. The standard Kobalt unit is better for light to medium duty tasks.
Are batteries included with these trimmers?
No batteries are included. Every listed product is sold as a tool-only unit. You must supply your own compatible battery. This design assumes you already own batteries from the respective brand ecosystem. Check your existing tool inventory before purchasing.
What is the difference between the Makita 40V and 18V models?
The Makita 40V model features a 15-inch cutting width and high torque. The Makita 18V model has a narrower 13-inch width. The 18V version weighs 9.23 pounds. The 40V version is designed for heavier duty work. Choose the 40V for power and the 18V for precision.
