5/5 across 1,869 reviews on Ace Hardware. Nobody reviews saws here; that number is theirs.

The bigger M18 sibling of the M12 Hatchet that climbing arborists made famous — an 8" one-hand-capable pruning saw that Milwaukee rates faster-cutting than 25cc gas while weighing under 5 lbs bare. It comes arborist-ready out of the box: lanyard loop, climbing scabbard, full-house low-vibration chain, metal bucking spikes, and onboard scrench storage. Owner threads treat it as the tool that ended the pole-saw-and-handsaw shuffle for limbing, storm cleanup, and trail work, and the review consensus at retail is near-perfect. The honest caveats: at $499 for the kit with the XC6.0 pack it costs as much as a full-size 16" saw kit; a one-handed 8" chainsaw invites the same kickback and PPE responsibilities as any top-handle saw; the tiny bar means it's a limbing specialist, not a bucking saw; and the auto-oiler shares the M18 family habit of seeping bar oil between uses. Pros on a budget note the tool-only at $279 makes more sense if you already own HO batteries.

Best for: Arborists, orchardists, and anyone doing regular limbing or storm cleanup who wants a one-hand-capable saw on the M18 platform.

Common complaints

$499 kit costs full-size-chainsaw money for an 8" bar; tool-only at $279 is the smarter buy for M18 owners
8" bar and modest oiler make it strictly a limbing/pruning tool — bucking anything past ~6" is out of its lane
One-hand ergonomics tempt unsafe technique; it demands the same PPE and respect as a top-handle saw
Seeps bar oil in storage like its bigger M18 siblings, per owner threads
Proprietary 33-link 3/8" LP chain means fewer aftermarket loop options than standard sizes

Questions owners ask

What can you actually cut with an 8-inch bar?

Limbs and small stems up to about 6 inches — and within that lane it's outstanding, cutting hardwood limbs faster than 25cc gas pruners while weighing under 5 lbs bare. Bucking anything bigger is out of its lane; the bar and modest oiler are sized for pruning and storm cleanup, not firewood.

Is it safe to use one-handed?

It's one-hand-capable, which is exactly why it demands respect: the ergonomics tempt unsafe technique, and it deserves the same PPE and kickback awareness as any top-handle chainsaw. Milwaukee builds it arborist-ready — lanyard loop and climbing scabbard in the box — which tells you the intended audience is people trained for this class of tool.

Should I buy the kit or the bare tool?

If you already own M18 packs, the $279 bare tool is the smarter buy — the $499 kit costs full-size-chainsaw money for an 8-inch saw. It runs on any M18 battery; the kit's XC6.0 is a good balance of weight and runtime, but a pack you already own works fine for intermittent pruning.

Are replacement chains easy to find?

Less so than standard sizes — it runs a 33-drive-link 3/8 low-profile .043 loop (Milwaukee 49-16-2750), and aftermarket options are thinner than for common chain sizes. Order a spare with the saw. The full-house chain it ships with is worth keeping in the rotation: it cuts smooth, low-vibration, and leaves clean pruning wounds.

Why pick this over a small gas top-handle?

Instant response and zero ceremony: full throttle in under a second, no priming, choking, or idle-hunting between cuts, and nothing to drain for storage. For intermittent pruning — where a gas saw spends half its life being restarted — that workflow advantage is the whole pitch, and near-perfect retail scores across thousands of ratings suggest owners agree.
