Makita 40V XGT Angle Grinders
Makita 40V XGT angle grinders are for hard site cutting and grinding when 18V starts feeling underpowered on steel, concrete, and masonry.
If you're chopping box section, dressing welds, or chasing out stubborn fixings all day, a Makita XGT grinder gives you the torque and runtime to stay on the job. Go brushless for less heat and better battery use, and match disc size to the work so you're not forcing it.
What Are Makita 40V XGT Angle Grinders Used For?
- Cutting steel on refurbs and fit-outs, like Unistrut, threaded rod, box section and rebar, without dragging a lead or waiting for a generator.
- Grinding and dressing welds on gates, handrails and structural brackets, where a Makita brushless angle grinder keeps the speed up under load instead of bogging down.
- Chopping out and trimming masonry and concrete with the right diamond blade, ideal when you need a Makita 40V site grinder that can take dust and abuse day after day.
- Cleaning up metalwork with flap discs and wire cups, stripping rust, paint and mill scale before you prime or re-finish on site.
- Fast snagging and fix removal, cutting seized bolts, anchors and brackets when nothing else shifts and you need Makita 40V cutting and grinding that just gets it done.
Choosing the Right Makita 40V XGT Angle Grinder
Sorting the right one is simple: match the grinder size and safety kit to what you cut all week, not what you cut once a month.
1. Disc Size and Guard Setup
If you're mostly on 1mm slitting discs and flap wheels, a smaller grinder is easier to control and less tiring. If you're regularly cutting thicker steel or deeper section, step up to the larger disc size so you're not forcing the cut and cooking discs.
2. Brushless Power for Proper Site Work
If it's occasional trimming and light grinding, most XGT models will cope. If you're cutting and grinding daily, go Makita brushless angle grinder every time because it holds speed better under load and wastes less battery as the job drags on.
3. Battery Capacity and Runtime
Don't kid yourself with one small battery if you're doing continuous metal cutting. If you're on a Makita XGT metal cutting grinder all day, run higher Ah packs and keep a spare charged, because grinders drain batteries faster than drills and impacts.
4. Safety Features You Actually Notice
If you're cutting overhead, working one-handed, or swapping between discs a lot, prioritise good guard adjustment, a proper side handle, and anti-kickback style protection. It's the difference between a tidy cut and a grinder that tries to climb out your hands.
Makita 40V XGT Angle Grinder FAQs
Is the Makita 40V any good?
Yes, especially on grinders where power draw is high. Makita 40V XGT angle grinders hold speed better under load and give you more usable runtime for cutting and grinding than lighter-duty setups, as long as you pair them with sensible battery sizes.
Is Makita 40V replacing 18v?
No. Makita 18V LXT is still a massive platform and ideal for plenty of day-to-day tools. XGT is the step-up range for higher-demand kit like grinders, saws and heavier drilling where you want more power and longer hard-use runtime.
Who has the best cordless grinder?
It depends what you're doing all week. For trade metal cutting and sustained grinding, the best cordless grinder is the one that holds speed, has proper safety features, and runs on a battery platform you already own. If you're already on XGT, a Makita XGT professional grinder is a solid choice because it's built for high-load site work.
What is Makita 40V Max?
Makita 40V Max is the XGT battery platform. It's a higher-voltage cordless system designed for tools that need more power and better load handling, like Makita 40V cutting and grinding, without being tied to mains.
Will a Makita 40V XGT grinder run standard 115mm and 125mm discs?
Yes, as long as you match the disc to the grinder's rated size and keep the guard set correctly. Don't try and squeeze a bigger disc on because it fits, it's unsafe and it'll work like rubbish.
Are Makita XGT grinder batteries interchangeable with 18V LXT?
No, XGT and LXT are different battery systems. If you're moving to Makita 40V XGT angle grinders, budget for the right XGT batteries and charger, or buy a bare unit if you've already got them.
Who Uses Makita 40V XGT Grinders?
- Steel erectors and fabricators who need a Makita XGT professional grinder for constant cutting, bevelling and weld clean-up without it feeling flat halfway through the day.
- Brickies, groundworkers and general builders using a Makita 40V cordless grinder for on-site trimming, cutting fixings, and rough grinding where mains power is a pain.
- Mechanical and maintenance teams keeping one in the van for plant repairs, bracket work and quick cut-offs, especially when access is awkward and time is tight.
How Makita 40V XGT Angle Grinders Work for You
A cordless grinder is only as good as how it holds speed under load and how it manages heat. XGT is built to keep cutting and grinding consistent, not just spin fast with no pressure on it.
1. Cutting vs Grinding Loads
Metal cutting is short, sharp bursts where the disc needs to stay stable and not stall. Grinding is sustained pressure that builds heat in the motor and battery. That's why Makita 40V cutting and grinding feels different to lighter platforms when you're leaning on it for longer.
2. Disc Choice Makes or Breaks the Job
A Makita 40V site grinder will still struggle if you fit the wrong disc. Use thin slitting discs for cut-offs, flap discs for finishing, and the right diamond blade for masonry, because forcing the wrong disc just drains batteries and chews guards and bearings.
3. Battery Platform Matters on Grinders
Grinders are high draw tools, so the platform and pack choice shows up fast in runtime. If you're buying into Makita XGT grinding tools for daily use, plan your batteries like you would for saws, not like you would for a drill driver.
Makita XGT Grinder Accessories That Save Time on Site
The right discs and a couple of essentials stop your grinder chewing batteries, burning materials, or leaving you with a messy finish.
1. Metal Cutting Discs and Flap Discs
Keep both in the box. Slitting discs get you clean cut-offs on steel, and flap discs finish welds and edges without gouging like a hard grinding disc when you're trying to make it look right.
2. Diamond Blades for Masonry and Concrete
If you're using a Makita 40V cordless grinder for trimming slabs or chasing, a proper diamond blade stops you glazing cheap discs and fighting the cut, especially on hard brick and concrete.
3. Spare XGT Batteries and a Fast Charger
Grinders rinse batteries, simple as that. A second pack and a decent charger stops you downing tools mid-cut or trying to bodge the last bit of a job with a dying battery.
4. Face Shield and Suitable Gloves
A grinder throws sparks, wire, and grit straight back at you. A proper face shield and gloves are the difference between cracking on and having to stop because you've taken a bit of wire wheel to the cheek.
