Makita Angle Grinder Disc Compatibility (2026) — What Fits Every Model
Author: Tool Compatibility Team | Published: March 2026 | Updated: March 2026
Makita angle grinders span cordless 18V and 40V platforms, plus workhorse corded models like the GA9020 (230mm). Each model has a specific disc size and bore specification. In this guide, we’ll show you exactly which discs fit every Makita grinder, from compact 115mm models to the industrial 230mm, plus recommendations for third-party and Makita-branded discs.
Quick Makita Angle Grinder Disc Compatibility Table
| Model | Disc Size | Bore Diameter | Max RPM | Type |
|---|---|---|---|---|
| DGA452Z | 115mm | 22.23mm (M14 thread) | 11,000 RPM | 18V LXT Cordless |
| DGA467Z | 115mm | 22.23mm (M14 thread) | 10,500 RPM | 18V LXT Cordless |
| DGA504Z | 125mm | 22.23mm (M14 thread) | 10,800 RPM | 18V LXT Cordless |
| DGA506Z | 125mm | 22.23mm (M14 thread) | 10,800 RPM | 18V LXT Cordless |
| GA005GZ | 125mm | 22.23mm (M14 thread) | 9,000 RPM | 40V XGT Cordless |
| GA9020 | 230mm | 22.23mm (M14 thread) | 6,600 RPM | Corded (2300W) |
| 9565CR | 125mm | 22.23mm (M14 thread) | 13,000 RPM | Corded (1400W) |
Key point: Almost all Makita angle grinders use the M14 thread bore (22.23mm), which is the industry standard. This makes it simple to swap discs across models—as long as you match the disc diameter and stay within the RPM rating.
18V LXT Cordless Grinders
Makita’s 18V LXT platform is their workhorse cordless range. These grinders are compact, lightweight, and ideal for DIY and light-to-medium trade work.
DGA452Z (115mm)
The DGA452Z is a ultra-compact 115mm grinder—one of Makita’s smallest offerings. It’s perfect for tight spaces, edge work, and detail jobs.
- Disc size: 115mm (4.5 inches)
- Bore: M14 (22.23mm)
- Max RPM: 11,000
- Battery: 18V LXT 1.3–5.0Ah (sold separately)
- Compatible discs: Any 115mm disc with M14 bore rated for 11,000 RPM or higher
Best disc types for DGA452Z: Cutting discs (metal/steel), stone cutting, tile cutting, flap discs for grinding/finishing.
DGA467Z (115mm)
Older sibling to the DGA452Z, the DGA467Z is still widely used. Specifications are nearly identical, with marginal RPM difference.
- Disc size: 115mm
- Bore: M14
- Max RPM: 10,500
- Compatible discs: Same as DGA452Z (any 115mm M14 disc rated 10,500 RPM or higher)
DGA504Z (125mm)
The DGA504Z bumps up to 125mm—a sweet spot for cordless work. Slightly more cutting power, still lightweight.
- Disc size: 125mm
- Bore: M14
- Max RPM: 10,800
- Compatible discs: Any 125mm M14 disc rated for 10,800 RPM or higher
DGA506Z (125mm)
Newer variant of the DGA504Z with slight ergonomic tweaks. Identical disc compatibility.
- Disc size: 125mm
- Bore: M14
- Max RPM: 10,800
- Compatible discs: Same as DGA504Z
Makita 18V LXT grinders typically use one LXT battery. See our best 18V LXT battery guide for recommended battery models and capacity upgrades.
40V XGT Cordless Grinders
Makita’s newer 40V XGT platform delivers more power and longer runtime than 18V, yet remains cordless. The GA005GZ is their flagship 40V grinder.
GA005GZ (125mm)
- Disc size: 125mm
- Bore: M14
- Max RPM: 9,000
- Battery: 40V XGT 4.0Ah or 5.0Ah (sold separately)
- Compatible discs: Any 125mm M14 disc rated for 9,000 RPM or higher
The GA005GZ uses the same 125mm disc standard as the 18V models, so you can share discs between platforms—great if you have both 18V and 40V tools.
40V XGT batteries cost more upfront but deliver higher sustained power compared to 18V LXT. If you already have XGT batteries for other Makita tools (impact driver, drill, etc.), the GA005GZ is a natural fit.
Corded Grinders
Makita’s corded angle grinders are industry standards. No battery worries, consistent power delivery, and trusted on job sites worldwide.
GA9020 (230mm)
The GA9020 is Makita’s workhorse 230mm corded grinder. Used on building sites, fabrication shops, and serious DIY projects.
- Disc size: 230mm (9 inches)
- Bore: M14
- Max RPM: 6,600
- Power: 2300W
- Compatible discs: Any 230mm M14 disc rated for 6,600 RPM or higher
Large disc safety note: 230mm discs are powerful and can generate significant heat and vibration. Always wear a full face shield, ensure your guard is properly adjusted, and use both hands. Check the disc flange (the clamping system) to ensure it’s not damaged.
9565CR (125mm)
A lighter, single-handed 125mm corded option—often overlooked but excellent for detail work and tight spaces on mains power.
- Disc size: 125mm
- Bore: M14
- Max RPM: 13,000
- Power: 1400W
- Compatible discs: Any 125mm M14 disc rated for 13,000 RPM or higher
The 9565CR’s high RPM makes it particularly effective for cutting thin metal and finishing flap disc work.
Makita-Branded Discs vs Third-Party Alternatives
Makita sells their own disc sets and individual discs (e.g., E-03034-12 cutting disc sets, flap disc packs). Should you buy Makita-branded?
Pros of Makita-branded discs:
- Guaranteed compatibility and quality assurance
- Tested and rated for Makita grinder RPM specs
- Often bundled in convenient multipacks
- Available at most tool retailers
Cons:
- Generally higher per-disc cost than third-party alternatives
- Limited disc type variety compared to specialist brands (e.g., Norton, Silverline)
Third-party discs are perfectly safe and legal to use provided they are:
- The correct diameter (115mm, 125mm, or 230mm)
- M14 bore (standard for Makita)
- Rated for your grinder’s RPM (check the disc label)
- From a reputable brand (Norton, Silverline, Draper, etc.)
Bottom line: Buy Makita-branded if you want guaranteed compatibility and don’t mind the extra cost. Otherwise, third-party discs from trusted brands are excellent value and will perform identically.

Frequently Asked Questions (FAQ)
Are all 125mm discs compatible with Makita angle grinders?
Most 125mm discs are compatible with Makita grinders, provided they have an M14 bore (22.23mm) and are rated for your grinder’s RPM. Makita’s 125mm models (DGA504Z, DGA506Z, GA005GZ, 9565CR) all use M14, making them interchangeable. However, always check the disc label for the maximum RPM rating—if your grinder spins faster than the disc rating, it’s unsafe to use. For example, a disc rated for 10,000 RPM can be used on the 9565CR (13,000 RPM max) only if the disc is certified for higher speeds.
Can I use DeWalt discs on a Makita angle grinder?
Yes, if they meet the specifications. DeWalt and Makita both use the M14 bore standard on their angle grinders. A DeWalt 125mm disc with M14 bore and appropriate RPM rating will fit and work on a Makita 125mm grinder. Always verify: (1) disc diameter matches your grinder (115mm, 125mm, or 230mm), (2) bore is M14, and (3) the disc RPM rating meets or exceeds your grinder’s maximum RPM. Brand is irrelevant—compatibility is determined by these physical and performance specs.
What disc fits the Makita DGA504Z?
The Makita DGA504Z accepts 125mm discs with an M14 bore (22.23mm) and a maximum RPM rating of 10,800 or higher. Compatible disc types include cutting discs, flap discs, grinding wheels, and stone cutting discs—provided they all have the correct size and bore. Makita-branded discs (e.g., E-03034-12) are guaranteed compatible, but third-party brands like Silverline, Norton, and Draper also work perfectly if they meet these specs.
Do Makita grinders use a standard bore size?
Yes. All Makita angle grinders—from the compact 115mm DGA452Z to the industrial 230mm GA9020—use the M14 thread bore (22.23mm diameter). This is the industry standard bore size, also used by DeWalt, Bosch, Milwaukee, and most other major brands. This standardisation means you can buy discs from any reputable manufacturer, as long as the disc diameter and RPM rating match your specific grinder model.
Summary: Makita Angle Grinder Disc Compatibility
All Makita grinders use the M14 bore—this single fact makes compatibility straightforward. Whether you own a cordless 18V LXT, the newer 40V XGT, or a corded workhorse like the GA9020, you can confidently buy discs from any major brand as long as you match:
- Disc diameter: 115mm, 125mm, or 230mm
- Bore: M14 (22.23mm)
- RPM rating: Equal to or higher than your grinder’s maximum RPM
Makita-branded discs offer peace of mind and bundled convenience; third-party brands from Norton, Silverline, and Draper deliver identical performance at lower cost. Stock a variety of disc types (cutting, flap, stone) and you’ll be ready for any project.
