Milwaukee M18 BJS Jigsaw UK Review – Tested and Rated

The Milwaukee M18 BJS sits in the middle of our best cordless jigsaws UK comparison – behind the Makita and DeWalt on raw performance metrics but ahead on warranty, with the same class-leading 5-year cover that Milwaukee extends across its M18 range. For an existing M18 platform user, it is the natural recommendation. At 2,700 spm with four orbital settings and a brushed motor, the specification is competitive with the DeWalt DCS331 and the performance gap between them is small in everyday use.

The M18 BJS is not the most technically advanced jigsaw in our comparison – the M18 BLJS brushless version exists for users who want the full brushless treatment on the Milwaukee platform. The BJS is the brushed entry point, and it sits at a competitive price for what is fundamentally a well-built, capable professional jigsaw backed by the best warranty in the class.

Overview and first impressions

The M18 BJS makes the same immediate quality impression as the rest of the Milwaukee M18 range – the red and black livery, the substantial feel and the build quality that Milwaukee maintains consistently across its professional tools. The grip is ergonomically sound with a comfortable overmould, and the balance with a standard blade fitted is good. At 1.7kg bare it is among the lighter tools in this comparison, which makes a positive difference for sustained overhead or one-handed cutting.

The blade change uses a tool-free key release system similar to the DeWalt. Blade retention is firm with minimal play, which keeps cut tracking accurate. The base plate pivots cleanly for bevel cuts up to 45 degrees and the locking mechanism is positive. Four orbital action settings are selected via a thumb dial with clear detent positions. The dust blower is functional and keeps the cut line reasonably clear, though it is less powerful than the dedicated blowers on the Makita and DeWalt.

Overall first impressions are positive. This feels like a tool built for sustained professional use – nothing feels flimsy, the controls operate positively and the grip geometry is comfortable across all cutting orientations. The 5-year warranty that applies to all registered M18 tools is a genuine differentiator that adds real long-term value for any trade professional who will use this tool regularly.

Specifications and scores

How it performed in our tests

The M18 BJS performed consistently well across all standard cutting tasks. In 18mm plywood on orbital setting 1, the cut was clean with a straight edge and good tracking on the marked line. In 45mm softwood at orbital setting 2, cutting speed was strong – slightly below the DeWalt DCS331’s 3,000 spm ceiling in straight runs, but the difference is not large in practice. In hardwood at orbital setting 0, the cut quality was very good with minimal tear-out on a fine-toothed blade.

The build quality impressed throughout the test period. The base plate remained stable and flat under all cutting conditions, the blade holder showed no play even after extended use, and the tool ran cool throughout a morning of sustained cutting. The lighter bare weight of 1.7kg made extended overhead cuts noticeably less tiring than with heavier rivals in the comparison.

Battery system and runtime

The M18 BJS runs on Milwaukee’s M18 platform – one of the most established professional cordless systems in UK trade, available at Screwfix and Toolstation as standard. The M18 range covers over 200 tools, which gives the platform practical depth for any trade professional already invested in it. M18 batteries are slightly less widely distributed in mainstream DIY retail than DeWalt XR, but for trade buyers sourcing from the standard trade counters this distinction rarely matters.

The brushed motor delivers competitive runtime per charge alongside the DeWalt DCS331 – both sit behind the Makita DJV182Z’s brushless efficiency. In our tests the M18 BJS delivered a solid morning of mixed cutting before needing a charge on a 3.0Ah battery, and a full working day on a 5.0Ah battery for all but the heaviest sustained use.

Performance and limitations

The M18 BJS is a capable, well-built jigsaw that sits comfortably in its position in our comparison. The performance is competitive with the DeWalt DCS331, the build quality is excellent and the 5-year warranty is the strongest in the class. Its limitations are the brushed motor – shared with the DeWalt – and the slightly less powerful dust blower compared to the Makita and DeWalt. Neither limitation is significant for most users, but both are worth noting for buyers deciding between the M18 BJS and the more expensive M18 BLJS brushless version.

Final verdict – is it worth it?

The Milwaukee M18 BJS is the right jigsaw for a specific buyer – one already invested in the M18 platform who values the combination of solid performance, excellent build quality and the best warranty in the class. The 5-year cover is a genuine differentiator. A jigsaw motor failure in year four costs nothing under Milwaukee’s warranty versus a significant repair or replacement bill with a 3-year covered rival.

Against the DeWalt DCS331 the comparison is close – the Milwaukee is lighter, better warranted and has fast charging, while the DeWalt has a slightly higher stroke rate and wider battery retail availability. Neither advantage is large enough to justify switching platforms. Against the Makita DJV182Z, the Makita leads on cut precision and brushless efficiency but lacks the 5-year warranty. For heavy daily trade use where warranty matters most, the M18 BJS is worth serious consideration alongside the Makita.

The M18 BJS is honest value for an M18 platform user. It is not the top pick in our comparison but it delivers genuinely good performance, excellent build quality and the longest warranty in the class – a combination that justifies its position without reservation.
