Cordless Saw Spec Comparison

The measured baseline for cordless circular saws — blade diameter, no-load speed and bare weight across 60 listings — and the finding that matters more than any of them: the median saw in this category is a 4-inch compact, not the 7¼-inch standard most buyers picture when they search for one.

The category baseline

60 listings, of which the following carried usable data.

The category is not the one the search term implies

Both the 25th percentile and the median blade diameter are 101.6 mm — 4 inches. The 75th percentile is 161.9 mm, or about 6⅜ inches. The largest blade in the entire sample is 203 mm — 8 inches — and the familiar 7¼-inch framing size sits near the top of the distribution rather than in the middle of it.

That is a statement about what this category sells, not about what a circular saw is. Search “cordless circular saw” and the results are dominated by compact and mini saws — single-handed tools with 4-inch blades intended for sheet goods, trim and plunge cuts. The full-size framing saw exists in the category but is outnumbered.

The weight column reads consistently with that. A median of 3.22 kg is light for a framing saw and heavy for a mini saw, because the sample contains both. The interquartile range, 2.10 to 4.18 kg, is where the compact saws cluster.

The exclusion you should know about

Every figure above survived a unit check: we read the original text each number was extracted from and confirmed the unit was one the field can legitimately hold. One field in this category failed.

This is worth carrying to other categories: any specification field that both corded and cordless tools populate is a mixed population by default, and a category average over it is meaningless unless the two are separated first.

Reading the speed figure

No-load speed is one of the more comparable specifications in cordless tools, because it is measured without load and the method is therefore effectively fixed. The interquartile range here, 3,850 to 5,300 RPM, is narrow, which is what you would expect from a mechanically constrained figure.

One caveat on the extremes: the maximum in this sample is 22,000 RPM, which is a rotary-tool figure rather than a circular-saw one and reflects a listing whose category assignment we would not defend. The quartiles are unaffected — that is the reason this page quotes medians and quartiles rather than means and maxima throughout.

Blade speed at the rim, not spindle speed, is what governs cut quality, and rim speed depends on diameter as well as RPM. A 4-inch blade at 5,000 RPM and a 7¼-inch blade at 5,000 RPM are not doing the same thing to the workpiece.

How to place a saw against this

Check depth of cut at 45° as well as at 90°. Bevel capacity falls away faster than most buyers expect, and it is the figure that decides whether a saw can do rafter and stringer work.

The Products These Figures Come From

Of the 60 saws in this category, 29 publish every figure in the baseline above. All 10 are listed by price tier, then alphabetically — this is not a ranking, and a product appearing here means its listing is complete, nothing more. 4 listings are held back for a published figure far outside the category’s own range — a data defect rather than an unusual product. 15 are held back because the listing’s own title contradicts the specification field we would have printed. 1 is excluded for a specification we have confirmed to be wrong.

Notes on the Products at the Edges

Most of the products above sit inside the interquartile range on every figure, which is what the baseline already describes. These are the ones it does not: each is outside P25 or P75 on at least one published figure. The position is computed from the category statistics; the explanation is what the listing itself states.

Makita XSR01Z 36V (18V X2) LXT® Brushless Rear Handle… — Makita, $200-500

Weight of 5.49 kg sits above the category P75 of 4.15 kg. A rear-handle saw run from two LXT batteries, which is where the mass sits; the motor is rated 5,100 RPM.

Makita XSS02Z 18V LXT Lithium-Ion Cordless 6-1/2" Circular… — Makita, $75-200

Weight of 1.50 kg sits below the category P25 of 2.06 kg. Weighed as a bare tool — the listing quotes 7.3 lbs with a battery, which is not included — at 3,700 RPM with a 2-1/4” cut at 90°.

Specifications are the manufacturer’s published values as scraped for this corpus, not our own measurements — the same source, and the same limits, as the baseline above. Prices move daily, so we show the tier rather than an amount. Links to Amazon are affiliate links.

What this category does not publish

Brushless construction, torque and pack capacity all appear on a minority of listings, none reaching a usable sample, so none appear above. Depth of cut, which is the single most decision-relevant figure in the category, is almost never carried as a structured specification and has to be read from the manufacturer’s page. Arbor size is similarly absent, and it determines which blades will fit.

Nothing above is a recommendation, a ranking or a test result. We do not own these tools. The method, including the coverage threshold and the unit check, is on comparison methodology.
