Best CRAFTSMAN String Trimmer Edger

As an Amazon Associate we earn from qualifying purchases.

Looking for the best craftsman string trimmer edger? This page covers one model, the CRAFTSMAN 12-inch corded electric string trimmer and edger, model CMEST900. The Amazon listing, read from a stored scan dated 2026-10-23, says it has a 3.5-amp motor, a 12-inch cutting width, a turn-to-edge feature with a wire edge guide, and an automatic line feed. The listing says the cord is not included. The manufacturer’s product page confirms the corded design and gives a three-year limited warranty. The sections below separate those statements from the gaps.

Quick answer

The listing says this is a corded electric string trimmer and edger with a 3.5-amp motor and a 12-inch cutting width.
The listing says a turn-to-edge feature and a wire edge guide let you switch from trimming to edging, and an automatic feed spool extends the 0.065-inch line without tapping the ground.
The listing says “Cord Not Included.” Plan for a power cord before you buy, because the listing does not say which cord it means or how long it is.
Choose it for corded trimming and edging near an outlet. The manufacturer page gives a three-year limited warranty, but the listing does not state one.

What the manufacturer page adds

The CRAFTSMAN page describes the tool as a “versatile 3.5 amp electric string trimmer.” It says the trimmer “doubles as an edger for added versatility, with a turn-to-edge feature and wire guide for a clean edge.” It lists a “12-in cutting swatch with 0.065-in line,” a “Motor Type Brushed,” and a “3 Year Limited Warranty.” The page also lists a total of zero batteries, which fits a corded tool.

The page has one conflict. Its power field reads “Power Source Integrated Batteries,” while its own corded field and the listing’s title both say corded. This post treats the tool as corded and records the power-field wording as a conflict to clear with the seller before you buy.

Figures worked out from the listing

The formulas below use the stated numbers from the two sources. They are arithmetic on those numbers, not performance results.

Figure	Formula	Result
Cut radius	12-inch cutting width divided by 2	6 inches
Line diameter in millimeters	0.065 inch multiplied by 25.4	About 1.65 mm
Footprint from product dimensions	7.46 inches multiplied by 12 inches	About 89.5 square inches, with no height stated
Cutting width in centimeters	12 inches multiplied by 2.54	About 30.5 cm

The cut radius is half the stated width, so a 12-inch swatch reaches 6 inches from the center of the head. The listing states the cutting width and the line size, but it does not state a head speed, so these figures describe the stated geometry only. The footprint comes from the listing’s product dimensions field, which has no height.

Who it suits

This tool fits a homeowner who wants one corded electric tool for two jobs: trimming grass and weeds, and putting a clean edge along a walk, bed or drive. The listing says the turn-to-edge feature and wire edge guide let you switch between trimming and edging quickly, and its recommended uses read “Edging, Trimming.” That combination is the main reason to consider this model.

It also suits a yard where the work stays near an outlet. A corded tool runs from the outlet, so the practical limit is how far the cord reaches, not battery life. The listing gives no cord length, so check reach before you start.

Edging and trimming on one head

The listing says you can “QUICKLY SWITCH FROM TRIMMING TO EDGING with turn-to-edge feature and wire edge guide.” The manufacturer page says the trimmer “doubles as an edger for added versatility.” Both sources describe one tool that does both jobs. Neither gives an edge depth or a number of passes for an edge.

The Utah State University Extension page makes a planning point rather than a tool point: “Although it is more work, finished, neat edges can make a landscape look polished and attractive.” It also says to “Design the landscaped area so it requires a minimal amount of edging or trimming.” The page is about planning the beds, so use it as a reason to plan the edges before you cut.

Safety points before you start

The Cornell page says that “String trimmers are one of the most dangerous lawn and landscaping tools.” It advises you to “Check the ground before trimming for loose debris such as glass, metal, small stones, etc.” and to “Stop trimming if people are around or until they have passed.” Its clothing advice is specific: “These include long sleeves, long pants, closed-toed shoes, gloves, eye protection, and ear protection.” It adds to “Avoid wearing loosely draped clothing or things that can be caught by the spinning head.”

The Virginia Tech publication has a section titled “Safety Tips for Operating Lawn Edgers.” It says “Do not inspect, repair, or carry out maintenance on a lawn edger when it is running.” Its string trimmer advice includes “Maintain firm footing and balance when using a string trimmer. Make sure lighting is adequate and do not overreach.” It also says to “Secure long hair above the shoulder when operating a string trimmer.” These sources are general and do not name this model, so use them as general guidance for both modes of the tool.

Skip it if

Skip it if the cord is a problem. The listing says “Cord Not Included,” and it does not say which cord or what length you would need.
Skip it if you need a cordless tool. Both sources describe a corded trimmer, but the power field conflict means you should not assume a battery is part of this package.
Skip it if you need a cut wider than 12 inches. The listing gives 12 inches as the cutting width and no larger option.
Skip it if you plan to hang it on a wall without buying more. The integrated hook works with the VERSATRACK wall system, which the listing says is sold separately.
Skip it if you want a broader comparison first. The Greenworks vs EGO Power+ string trimmer comparison covers other models.

What the listing does not say

The listing is short on the points a corded buyer needs. It states that the cord is not included, but it gives no cord length, plug type or voltage. It does not give a weight, a shaft length, a height or a head speed. The table marks each of these as not stated.

Power cord: the listing says “Cord Not Included” and gives nothing else about the cord.
Battery and charger: not stated in the listing. The manufacturer page shows a total of 0 batteries.
Run time: not applicable to a corded tool, and the listing gives no figure.
Weight and shaft length: not stated in either source.
Head details beyond the feed: the listing names an automatic feed and a turn-to-edge feature, and gives no other head details.
Spare line: the listing names one prewound 0.065-inch line and says nothing about spare spools.

Buying checklist

Ask the seller which cord the “Cord Not Included” note refers to, and get its length.
Check the outlet location against the edges you plan to trim and edge.
Ask whether a battery is part of the package, since the manufacturer power field conflicts with the corded wording.
Ask whether the three-year limited warranty on the manufacturer page applies to the unit you buy, and read its terms.
Check that the 12-inch cutting width suits the strips you plan to trim.
Ask about spare spools, since the listing names only the prewound 0.065-inch line.

Mistakes to avoid

Assuming the cord is in the box. The listing says it is not included.
Assuming a battery is in the box. The manufacturer power field conflicts with the corded wording, so ask.
Overreaching while edging. The Virginia Tech publication says to “do not overreach” when using a string trimmer.
Doing maintenance while the tool runs. The Virginia Tech publication says “Do not inspect, repair, or carry out maintenance on a lawn edger when it is running.”
Trimming with people close by. The Cornell page says to “Stop trimming if people are around or until they have passed.”
Counting on the warranty from the listing alone. The listing does not state a warranty, and the three-year term comes from the manufacturer page.

For line replacement on a different brand, the Ryobi One Plus weed eater string post covers that topic for another trimmer.

How we chose

This model is in the post because it is a complete corded string trimmer and edger with its own listing record and a manufacturer product page. The post covers one product only, ASIN B08T6BRD6X. We did not compare it with other models in this post, so no ranking is claimed. The listing data comes from a stored scan record read on 2026-10-23. The manufacturer page was opened on 2026-10-23. The three university pages were opened on 2026-10-22 and are listed with their dates at the end of this post.

We used the manufacturer page for model facts it states, and we used the university pages only for general use and safety points. We did not use any retail, blog or comparison page for a fact in this post.

What we could not verify

The listing and the manufacturer page disagree on the power source wording, and neither gives the cord details. We could not resolve the conflict from the sources we opened.

Whether a battery is part of the package. The manufacturer power field reads “Integrated Batteries,” but its battery count is zero.
Which cord the “Cord Not Included” note refers to, its length and its rating.
Whether the three-year limited warranty applies to the unit you buy, and what its terms cover.
The weight, and the shaft length.
The head speed. Neither source gives an rpm figure.
Whether spare spools are sold separately.

The university pages describe string trimmers and edgers in general. They do not describe this model, and the post uses them only for general use and safety points.

FAQ

Does the CRAFTSMAN CMEST900 come with a power cord?

The listing says “Cord Not Included,” so plan on a cord of your own. The listing does not say which cord it means, what length it has, or what rating it needs. Ask the seller before you order.

Is the CMEST900 cordless?

No. The listing title says Corded Electric, and the manufacturer page marks the tool as corded. The manufacturer’s power field, though, reads Integrated Batteries, which conflicts with the corded marking. Confirm with the seller that no battery is part of the package.

Can it trim and edge?

Yes, according to both sources. The listing describes a turn-to-edge feature and a wire edge guide, and the manufacturer page says the trimmer doubles as an edger. Neither gives an edge depth or a pass count, so judge the result on your own edges.

How wide is the cut, and what line does it use?

The listing states a 12-inch cutting width with a 0.065-inch line. The manufacturer page gives the same 12-inch cutting swatch and 0.065-inch line. The page does not give a head speed or a line feed rate.

Does the warranty cover this tool?

The manufacturer page lists a three-year limited warranty. The listing does not state a warranty, so the manufacturer page is the only source for that term. Read the warranty terms before you buy, because this post does not reproduce them.

Can I hang it on a wall?

The listing says the integrated hook is compatible with the VERSATRACK wall organization system, which is sold separately. The listing does not describe another way to hang the tool.

Bottom line

Buy this CRAFTSMAN CMEST900 if you want one corded electric tool that trims and edges near an outlet, and confirm the cord and the battery question with the seller before you order. If the seller cannot clear up the cord and power-field questions, choose a different model.
