Metabo Angle Grinder Disc Compatibility (2026)
Complete guide to finding the right discs for every Metabo grinder model
Metabo is Germany’s premium power tool brand—less well-known in the UK than Bosch or Makita, but absolutely revered by European professionals. If you’ve invested in a Metabo angle grinder, you’ve chosen a tool built to exacting engineering standards with a focus on safety and longevity.
The good news: Metabo grinders use the universal 22.23mm bore, meaning disc compatibility is straightforward. This guide covers every current Metabo model and helps you find the right discs at the best price.
Quick Compatibility Table: Metabo Angle Grinder Models (2026)
| Model | Type | Disc Size | Bore Diameter | Max RPM | Power / Battery | Special Features |

Key note: All Metabo grinders use the standard 22.23mm bore. Any third-party disc designed for this bore (Bosch, Makita, Silverline, etc.) will fit perfectly.
Why Choose Metabo? German Engineering Explained
Metabo is not as visible in UK high street retail as Bosch or Makita, but for good reason: the brand focuses on professionals and serious users, not casual DIY customers. Here’s what you’re getting with a Metabo grinder:
Safety: S-Automatic Clutch
Most Metabo grinders include the S-automatic clutch—a safety feature that instantly stops disc rotation if the disc jams or catches. This dramatically reduces the risk of wrist injury from sudden twisting. Professional tools include this as standard; budget brands rarely do.
When the disc stops suddenly (e.g., jamming in metal), the clutch disengages in milliseconds. Your wrist doesn’t rotate with the disc. This is not a gimmick—it’s a critical safety feature that has prevented thousands of workplace injuries.
Motor Longevity
Metabo designs their motors for marathon use. Brushless designs (on cordless models) eliminate brush wear, meaning less maintenance and longer life. Corded models use heavy-gauge copper windings and premium bearings rated for thousands of hours of continuous operation.
Professional contractors report Metabo grinders running reliably after 10+ years of regular use. Budget brands often need replacing after 2–3 years of professional duty.
Variable Speed (Corded Models)
The WEP2200-230 and some other Metabo corded grinders offer electronic variable speed control. This lets you match RPM to the task: lower speed for grinding (safer, better control), higher speed for cutting (more aggressive). Budget grinders run at fixed RPM.
Build Quality
Die-cast aluminium housing (not plastic), precision-machined spindles, sealed bearings, and robust gearboxes. Metabo tools are heavier than budget alternatives, but that weight is quality engineering, not poor design.
Price Premium
Metabo grinders cost 20–40% more than equivalent Bosch models, and significantly more than budget brands. You’re paying for professional durability, safety features, and German precision. If you use a grinder daily on job sites, the investment pays back in reliability and reduced downtime.
Availability in the UK
Metabo isn’t stocked by every DIY superstore. You’ll find Metabo through specialist tool retailers (Screwfix has some models, though limited), Amazon UK, and professional tool distributors. This makes sourcing slightly less convenient than Bosch, but entirely doable.
Cordless Models: 18V and 36V Power
W18LTX125 (18V Brushless, 125mm)
Disc size: 125mm | Bore: 22.23mm | RPM: 10,000 | Battery: 18V LiHD (3.1Ah or 5.2Ah)
Metabo’s flagship cordless model. Brushless motor, S-automatic clutch, and a 125mm disc give this tool serious cutting and grinding capacity. The 18V LiHD battery is Metabo’s premium li-ion chemistry, delivering excellent runtime and longevity (up to 3,000+ charge cycles).
What it’s good for:
- Job-site cutting and grinding where corded power isn’t available
- Sustained professional use (8+ hours per day with spare batteries)
- Contractors who need tool-free quick-change (though Metabo doesn’t use X-LOCK, the standard nut is quick once you’re used to it)
- Users in the Metabo 18V ecosystem (Metabo cordless drills, saws, etc.)
Runtime: Approximately 25–30 cuts (cold rolled steel tube, 30mm diameter) on a single 5.2Ah battery. Excellent for a day’s work with one or two spare batteries.
WPB36-18LTX230 (36V Dual-Battery, 230mm)
Disc size: 230mm | Bore: 22.23mm | RPM: 6,600 | Battery: 36V (2×18V LiHD), up to 5.2Ah each
Heavy-duty cordless grinder for professionals. The 36V system (dual 18V batteries) delivers the power equivalent of a mid-range corded grinder. Perfect for job sites where cutting deep steel or extended grinding is required, but corded isn’t practical (no nearby power, or mobility needed).
What it’s good for:
- Professional cutting and grinding (construction, fabrication, demolition)
- Large-diameter disc work (230mm cuts deeper and faster than 125mm)
- Jobs requiring sustained power without being tethered to mains
- Contractors with multiple Metabo 36V tools
Considerations: Heavy tool (6–7kg), requires two-handed operation for safety. The 230mm disc demands experience and respect. Not a beginner’s grinder, but an excellent professional choice.
Corded Models: Unlimited Power
W9-115 (115mm, 900W)
Disc size: 115mm | Bore: 22.23mm | RPM: 11,000 | Power: 900W
Entry-level Metabo corded grinder. Still includes the S-automatic clutch, making it safer than most cordless grinders from other brands. The 115mm disc is ideal for detail work, cutting rebar, and light grinding. Perfect if you need reliability without the 230mm capacity.
Advantages over cordless: Unlimited runtime, no batteries to charge, lower cost than cordless models, always ready to use.
WEP2200-230 (230mm, 2,200W, Variable Speed)
Disc size: 230mm | Bore: 22.23mm | RPM: 6,600 (variable) | Power: 2,200W
Professional-grade corded grinder. The 2,200W motor is one of the most powerful 230mm grinders on the market. Variable-speed electronic control lets you dial down RPM for grinding (safer, better control) or push to maximum for aggressive cutting. The S-automatic clutch and sealed power switch add professional safety.
What it’s good for:
- Daily professional use on construction sites, in fabrication shops, metal processing
- Cutting and grinding thick steel, stainless steel, cast iron
- Contractors who demand the best performance and reliability
- Jobs requiring variable speed for precision
Cost: Expect to pay £400–£600 for the WEP2200-230. High price, but it’s comparable to professional Bosch or Makita 230mm models and is considered one of the best grinders available.

Frequently Asked Questions
What is the S-automatic clutch, and why does it matter?
The S-automatic clutch is a safety feature that instantly disengages the motor if the disc jams or catches. If the disc suddenly stops rotating due to binding in the work, the motor continues spinning (harmlessly), but the disc stops. This prevents violent hand rotation that can break wrists. It’s a critical safety feature on professional tools and should be on any grinder you use daily.
Are Metabo grinders available in the UK?
Yes, but with limited retail presence compared to Bosch or Makita. Available through Amazon UK, Screwfix (some models), and specialist tool retailers. Not typically stocked in DIY superstores, but entirely obtainable online. Discs are universally available.
Can I use non-Metabo discs on my Metabo grinder?
Absolutely. All Metabo grinders use the standard 22.23mm bore. Bosch, Makita, Silverline, 3M, Pferd—any 22.23mm bore disc fits perfectly. This gives you complete flexibility to choose by price, quality, or application rather than brand loyalty.
What’s the difference between the W18LTX125 and GWX18V-15SC (Bosch)?
Both are 125mm cordless grinders. The Metabo is heavier, more robust, includes S-automatic clutch, and has longer battery life (LiHD technology). The Bosch is lighter, cheaper, and includes X-LOCK for tool-free disc changes. Metabo for professional use; Bosch for DIY/occasional work.
Is the WEP2200-230 worth £400–£600?
If you use a 230mm grinder multiple times per week on job sites, yes. The variable speed, S-automatic clutch, build quality, and motor longevity mean the tool will outlast cheaper competitors by years. If you cut occasionally, buy a budget Bosch or Silverline grinder instead.
Can the W18LTX125 handle 230mm discs?
No. The grinder is designed for 125mm discs only. Using a larger disc will not fit the guard, exceeds the tool’s rated capacity, and is dangerous. Always use the correct disc size for your grinder model.
Are Metabo batteries compatible with other brands?
No. Metabo 18V LiHD and 36V batteries only work on Metabo tools. You cannot use Bosch or Makita batteries in a Metabo grinder. If you already own Bosch or Makita tools, choose those brands for your grinder to leverage existing batteries. Choose Metabo only if building a dedicated Metabo ecosystem.
Summary: Metabo—German Engineering for Professionals
Metabo grinders are not mainstream in UK retail, but they’re absolutely worth considering if you value reliability, safety, and professional-grade engineering. Every Metabo model includes S-automatic clutch safety, precision-engineered motors, and robust construction designed for thousands of hours of daily use.
Quick buying guide:
- Professional cordless work: W18LTX125 (125mm, 18V brushless) with Bosch or Makita discs.
- Heavy-duty cordless: WPB36-18LTX230 (230mm, 36V dual-battery).
- Corded professional: WEP2200-230 (230mm, 2,200W, variable speed)—the best 230mm grinder available.
- Budget corded: W9-115 (115mm, 900W)—still includes S-automatic clutch for safety.
All Metabo grinders accept universal 22.23mm bore discs. Pair with Bosch Rapido or Makita discs for professional results, or Silverline for budget cutting. The grinder is the investment; discs are consumables—buy quality discs but prioritise the grinder reliability.
