Last updated November 9, 2026
The Seesii M8 Boost mini chainsaw is the best 8-inch chainsaw for most buyers: its two 4000mAh batteries and brushless motor let you work through a pile of limbs without stopping to recharge, and the tool-free chain tension saves you a wrench in the yard. An 8-inch bar gives roughly 6 to 7 inches of clean cut in softwood, less in hardwood, so it handles branches, saplings and small rounds rather than felling or firewood.

What an 8-inch bar can and cannot cut
An 8-inch bar gives roughly 6 to 7 inches of clean cut in softwood, and less in hardwood. The printed bar length is measured from the tip to the nearest cutter and rounded up, so the usable length is always shorter than the number on the box. When you buck a log that lies flat on the ground, the bar has to reach past the full diameter without the powerhead fouling the wood, which cuts the usable depth again.
Inside the limit: limbing a fallen tree, pruning branches, cutting small rounds and kindling, and clearing saplings and brush. Outside it: anything where the bar has to bury itself completely, and any log where the cut has to be finished from the other side. A clean single-pass cut is the check of whether the saw is the right size for the job. A saw forced into a two-sided cut is being asked to do work it was not built for.
Why 8-inch saws are one-handed tools and what that means for safe use
The 8-inch class is built as a one-hand top-handle format: the rear handle sits over the top of the powerhead so the saw can be held and guided with one hand while the other holds the branch. A rear-handle saw puts both hands on the tool and gives leverage against kickback. On a one-hand saw the chain is closer to the body, the bar nose is closer to the off hand, and there is no second grip to resist a kickback, so the rules tighten rather than loosen.
Keep the off hand clear of the bar's path and never in line with the cut. Stand to the side of the cut rather than behind the bar. Keep the saw below shoulder height, never cut overhead, and never work from a ladder. Keep the bar nose out of the wood to avoid the kickback zone. The small format makes the saw feel harmless, which is exactly why the rules need stating.
Bar and chain sizes specific to 8-inch saws
8-inch bars in this class commonly run 3/8-inch low-profile or 1/4-inch pitch micro chain, with low-profile gauge and a drive-link count that varies by bar. Bar mount patterns differ between saws even when the length is the same. Pitch, gauge and drive-link count all have to match the bar, and the bar's own markings carry these figures. A chain of the right length but the wrong pitch or gauge will not run correctly. Low-kickback chain is common in this class and is the sensible choice for a one-hand saw.
When an 8-inch saw is the wrong tool
Felling a standing tree, bucking logs over about 8 inches, sustained cutting such as a season's firewood, and any job where the bar has to stay buried for more than a moment all call for a larger saw. Overworking looks like the saw bogging down, the chain stalling, the motor and battery getting hot, and the cut taking minutes instead of seconds. Forcing the saw through anyway is where both damage and injury happen.
For anything overhead or out of reach, use a pole saw. For anything under about an inch and a half, use loppers or a pruning saw. An 8-inch saw is an excellent second tool and a poor only tool for a reader with a woodpile to build.

Frequently asked questions
The questions that come up most often once a reader has settled on an 8-inch bar.
What can an 8-inch chainsaw cut?
Limbs, branches, saplings and small rounds. The usable depth shrinks further when you buck a log lying flat on the ground.
Can an 8-inch chainsaw cut a 6-inch branch?
Yes. A 6-inch branch is the sweet spot of the class, with enough bar left over to keep the powerhead clear of the wood.
Can it cut an 8-inch log?
Only by finishing the cut from the other side, which is not what the saw is built for. A log that size wants a longer bar.
Is an 8-inch chainsaw big enough to fell a tree?
No. It is a limbing and pruning saw, built for branches and small rounds rather than standing timber.
Do 8-inch chainsaws come in gas?
No. The class is battery and corded electric.
Is an 8-inch chainsaw one-handed or two-handed?
One-handed. The compact format puts the chain close to your body, so grip and stance rules matter more, not less.
What chain does an 8-inch bar take?
Low-profile micro chain in the 1/4-inch or 3/8-inch pitch class. Pitch, gauge and drive-link count must match the bar's markings.
