At a glance
The Makita DGA463Z is the brushless version of Makita’s compact 115mm angle grinder, sitting one step above the well-established DGA452Z in the LXT range. The brushless motor is the headline difference – it runs cooler, lasts longer and extracts more performance from the battery than the brushed motor in the 452Z, which translates in practice to more cuts per charge and a tool that handles extended use sessions without the heat build-up that can limit the older model. For tradespeople and serious DIYers who already own Makita LXT batteries and use an angle grinder regularly, the DGA463Z is the version worth buying.
We tested the DGA463Z alongside the rest of the 115mm cordless angle grinder field on a range of tasks that represent typical UK use – cutting mild steel box section, grinding back welds, removing old mortar from brickwork, and surface prep work on a garden gate. The aim was to establish whether the brushless upgrade delivers a meaningful real-world improvement over the brushed equivalent, and whether the price premium is justified for the tasks most UK buyers will actually use it for.
Overview and first impressions
The DGA463Z is a compact, well-balanced tool that sits comfortably in the hand for both single-hand operation and with the side handle fitted. The body dimensions are virtually identical to the DGA452Z, which is a deliberate design choice – Makita wanted the brushless upgrade to be a direct replacement in existing workflows rather than a redesign that would require users to relearn the tool. The main external differences are subtle: the brushless motor housing is marginally slimmer, the labelling identifies the brushless motor with Makita’s BL designation, and the electronic speed control gives the motor a noticeably smoother ramp-up to full speed compared to the more abrupt start of the brushed version.
The build quality is exactly what you expect from Makita’s LXT range at this price point – solid, professional and reassuring without being over-engineered. The rubberised grip areas are well-placed, the paddle switch with lock-off lever is properly protective and the tool-free guard adjustment operates smoothly. Disc changes via the spindle lock are quick and reliable. Nothing about the handling or ergonomics has changed significantly from the 452Z, which means existing users will feel immediately at home.
The DGA463Z is sold body only in all UK listings. An 18V LXT battery and charger are required and not included. For new buyers without existing Makita batteries, add approximately £60-90 for a quality 5Ah battery and charger. The brushless motor benefits most from a high-capacity battery – a 4Ah or 5Ah BL1850 or BL1840 is the correct choice for this tool.
Specifications and scores
How it performed in testing
Cutting mild steel box section is the everyday workhorse task for a 115mm grinder and the DGA463Z handles it well. With a fresh 4Ah battery we cut through 40x40x3mm box section cleanly and consistently, with no noticeable loss of speed under load across the first fifteen or so cuts. The brushless motor’s electronic speed control maintains disc speed more effectively than the brushed DGA452Z – there is less of the characteristic slow-down under load that can affect cut quality with brushed motors. For trade use involving sustained cutting sessions this is the most practically significant difference between the two models.
Grinding back welds on mild steel plate was similarly composed. The DGA463Z stayed smooth and controlled throughout, with vibration levels that are comfortable for extended work without gloves and manageable with the standard side handle providing the control needed for precision grinding. The no-load speed of 8,500rpm is on the lower side for a 115mm grinder – some competitors run to 9,000-10,000rpm – but in practice the brushless motor’s torque characteristics mean it feels more powerful under load than raw rpm figures suggest.
Mortar removal from old brickwork was the most demanding task in our test sequence. The DGA463Z maintained a consistent pace throughout but generated noticeably more heat at the battery connection than the other 115mm grinders in our test group. This is characteristic of high-current brushless motors working hard – the BMS (battery management system) in quality Makita batteries handles it well and we did not experience any thermal shutdowns, but it reinforces the recommendation to use a 4Ah or 5Ah battery for sustained heavy work rather than the lighter 2Ah packs.
Battery and runtime
The DGA463Z runs on Makita’s 18V LXT platform, which is the most widely used cordless battery system among UK tradespeople. The LXT ecosystem covers over 200 compatible tools, which means anyone investing in the platform can share batteries across drills, jigsaws, sanders, impact drivers and dozens of other tools. This is the primary reason many UK buyers choose Makita – not necessarily because any individual tool is categorically superior, but because the battery investment pays dividends across an entire workshop.
Performance and limitations
The DGA463Z performs well across its intended use cases – metalworking, surface prep and light masonry work. Where it stands out versus the brushed DGA452Z is in sustained performance: the brushless motor maintains more consistent disc speed across longer working sessions, generates less internal heat and will deliver a longer service life before motor wear becomes an issue. For a tool that gets used every day on a building site, this is meaningful. For a DIYer who picks up an angle grinder three times a year, the difference is largely academic.
The 115mm disc size is the main practical limitation. It is the most versatile size for the tasks most users need – fitting in tight spaces, light cutting, weld grinding, surface prep – but it is not a heavy-duty cutting tool. For cutting thick plate steel or rebar, a 125mm or 230mm grinder is more appropriate. The DGA463Z is at its best as a precision, lightweight tool for metalwork rather than a brute-force cutter.
- Brushless motor maintains speed under load better than the 452Z
- Compact and well-balanced – comfortable for extended use
- Full LXT compatibility – shares batteries with 200+ tools
- Tool-free guard adjustment and fast disc changes
- Body only – adds cost for buyers without LXT batteries
- Premium over brushed DGA452Z is hard to justify for occasional users
- 115mm limits heavy-duty cutting applications
- Runs warm under sustained heavy load
- Existing Makita LXT users adding a grinder to the collection
- Tradespeople who use a grinder daily and need sustained performance
- DIYers doing metalwork, gate maintenance or weld grinding
- New buyers without any LXT batteries – total cost rises significantly
- Occasional users who will not benefit from the brushless motor upgrade
- Anyone needing heavy-duty cutting of thick steel – use a larger disc size
Final verdict – is it worth it?
The Makita DGA463Z is a genuinely good angle grinder that earns its place in the LXT lineup through a combination of solid build quality, effective brushless performance and the unmatched convenience of battery compatibility with the wider Makita ecosystem. For anyone already invested in LXT tools, it is the obvious choice when a 115mm angle grinder is needed – the body-only pricing is lower than it initially appears once you factor in the batteries you already own.
Where the decision becomes less clear-cut is for buyers starting fresh without existing LXT batteries. The DGA452Z brushed version is meaningfully cheaper and performs well enough for most DIY and light trade use. Unless you are grinding or cutting for extended sessions regularly, the brushless motor’s advantages – longer service life, better sustained performance – may not be sufficient to justify the price premium over the brushed alternative. For tradespeople who use a grinder every working day, the calculus is different and the brushless motor will pay for itself in longevity and consistency.
At the body-only price with existing batteries, the DGA463Z sits comfortably among the best 115mm cordless grinders in the UK market. It does not redefine the category or offer a dramatic step change from the competition, but it does what it promises reliably and without fuss – which is exactly what most users need from a tool in this class.
A well-built brushless angle grinder that delivers consistent performance for LXT users. The brushless motor makes a meaningful difference in sustained heavy use and the LXT battery compatibility is a genuine advantage for anyone already in the Makita ecosystem. For occasional users, the DGA452Z represents better value. For regular users and tradespeople already on LXT, the DGA463Z is the right choice.
