JCB 210mm Sliding Mitre Saw Review (21-MS-210-SB)
1500W, sliding rails, a laser guide and a 24T blade that cuts wood, mild steel, aluminium and plastic — for around £100. The JCB 210mm mitre saw reviewed, with the honest capacity caveat. 4.3/5.
Key takeaways
- Capacity is the honest limit: 70mm depth at 90° covers most DIY, decking and trim work, and anyone cutting bigger stock should look at JCB's 254mm sibling (£160 direct).
- A fixed compound mitre saw chops only as wide as its blade's arc; a slider carries the blade forward on rails, cutting stock far wider than the blade diameter alone allows.
- 70mm at 90° and 35mm at 45° handles most trim, board and rail work, but chunky sleepers, thick joists and deep fence posts will exceed it.
- The free Loxa insurance offer applies to Pro tools, so don't assume it here.
- 🏆 Mark's Verdict - 4.3/5 Sliding capacity, 1500W, a laser and a blade that eats four materials, for roughly £100: the 21-MS-210-SB makes the chop-station decision cheap enough to stop deferring .

JCB 210mm Sliding Mitre Saw Review (21-MS-210-SB): Multi-Material Cutting on a Budget
By Mark Moore, Power Tools Editor · Updated 04 August 2026 · 9 min read
⚡ Quick Verdict - 4.3/5
A 1500W sliding mitre saw with a laser guide, dust collection and a 24T multi-material TCT blade that cuts wood, mild steel, non-ferrous metal and plastic - at a price around the £100 mark at authorised stockists that makes established rivals look expensive. Capacity is the honest limit: 70mm depth at 90° covers most DIY, decking and trim work, and anyone cutting bigger stock should look at JCB's 254mm sibling (£160 direct). For home workshops, garden builds and a second site saw, the value is hard to argue with.
JCB's saw line - "precision in every cut" - is the newest front in the range's expansion, and the 21-MS-210-SB sliding mitre saw is its centrepiece: an 8-inch slider aimed at the home improver and the trade buyer who needs a competent chop station without premium-brand money. For our garden-side readers, this is the saw for decking builds, fence rails, pergolas and raised beds - the cross-cut workhorse of outdoor carpentry.
One orientation note: unlike the Pro 18V cordless system we've been reviewing, this is a 230V corded machine from JCB's wider tool catalogue, with its own warranty scheme (more below).

Why "sliding" matters
A fixed compound mitre saw chops only as wide as its blade's arc; a slider carries the blade forward on rails, cutting stock far wider than the blade diameter alone allows. That's what makes this the decking-and-shelving format - wide boards, cross-cut cleanly at set angles, with the 4 mitre stops and 90–45° bevel covering skirting, architrave, frames and fence rails. The laser line earns its keep on repeat cuts, and the dust bag keeps the worst of the mess captured (connect extraction for indoor work, mitre saws are dust fountains).
The multi-material blade - the unusual bit
Most saws at this price ship a wood-only blade. The 24T TCT fitted here is specified for wood, mild steel, non-ferrous metals and plastic, which for the practical buyer means fence posts and the angle-iron bracket, decking boards and the aluminium trim, without a blade swap. Two honest notes: a 24T count is a fast, general-purpose cut, so fine furniture-grade finish work wants a higher-tooth blade (JCB's own blade range covers it); and cutting metal in any mitre saw means eye protection, clamped stock and patience, per the manual.
Capacity honesty - and the family ladder
70mm at 90° and 35mm at 45° handles most trim, board and rail work, but chunky sleepers, thick joists and deep fence posts will exceed it. JCB's saw family has a rung for each budget: a 1100W 210mm compound (entry chop saw), a 1100W 210mm slider, this 1500W slider and the 254mm 10" sliding model (21-MS-254SB) at £160 direct, which is the answer if your projects live in bigger timber. There's also an extending mitre saw stand (200kg capacity) in the accessories line for anyone making this a permanent station. If you're weighing this class at all, the £60ish step to the 254 is worth pricing before you commit, capacity is the one spec you can't upgrade later.
Warranty note - different scheme from Pro 18V
The saws sit outside the Pro cordless range's warranty structure: this machine carries a 3-year platinum warranty for home use (register it) or 1 year commercial, with parts and service backup - generous for home buyers, and worth knowing for trade buyers comparing against the Pro tools' flat 3-year terms. The free Loxa insurance offer applies to Pro tools, so don't assume it here.
✔ Pros
Sliding capacity + 1500W around the £100 mark · genuine multi-material 24T TCT blade · laser, dust bag, soft grip as standard · 3-year home warranty (registered) · light enough (~9.8kg) to move between jobs · 254mm sibling and stand available
✘ Cons
70mm/35mm depth rules out big timber - that's the 254's job · 24T blade is general-purpose, not fine-finish · corded 230V only · commercial warranty drops to 1 year · motor spec (brushless or not) is described inconsistently across listings
🏆 Mark's Verdict - 4.3/5
Sliding capacity, 1500W, a laser and a blade that eats four materials, for roughly £100: the 21-MS-210-SB makes the chop-station decision cheap enough to stop deferring. Know its 70mm ceiling, register the warranty on day one, and let the 254 have the big-timber jobs. For garden carpentry and home workshops, it's an easy recommendation.
