Head to Head on What Matters

Motor Speed and Control

Speed is where these grinders start to differ. The Makita XAG11Z, Makita XAG26Z, and Heimerdinger 5 Inch Brushless all state their top speed clearly. The two Makita models deliver 8,500 RPM, while the Heimerdinger reaches up to 6,000 RPM. The Makita XAG20Z takes a different route with a variable speed control dial. It lets you adjust the speed manually from 3,000 to 8,500 RPM to match your specific job. The rest of the lineup doesn’t list an exact RPM figure in its product data. That means their top speed remains unknown rather than zero. If you need a set speed for delicate tile work, the XAG20Z gives you that dial. For fast metal cutting, the 8,500 RPM models have the stated numbers.

Wheel Size and Mounting System

Every single grinder in this group accepts either a 4-1/2 inch or 5 inch disc. The Makita DGA517Z lists its size as 125mm, which is the metric equivalent of those same discs. You won’t find a difference in maximum cutting depth between them based on the listings. However, how you attach that wheel changes completely with two specific models. The Makita XAG17Z and the Makita XAG26Z both feature the X-Lock quick change system. This allows for tool-free wheel changes using a simple snap-on mount and a pull release lever. The other eight grinders use a traditional mounting setup. If you swap discs often during a shift, the X-Lock mechanism saves time and removes the need for a wrench.

Safety Features and Warranty

Safety technology is listed heavily across most of these Makita tools. Active Feedback-sensing Technology (AFT) appears on the XAG04Z, XAG11Z, XAG20Z, and XAG26Z. AFT turns the motor off immediately if the wheel’s rotation is suddenly forced to stop. An electric brake is another key feature found on the XAG11Z, XAG20Z, and XAG26Z. It stops the grinding or cut-off wheel in 2 seconds or less. Anti-restart functions show up on the DGA517Z, DGA455Z, and DGA452Z to prevent accidental startups when changing batteries. Only the Makita DGA517Z states a specific warranty length in its listing. It comes with a 1 year manufacturer warranty, plus a further 2 years when registered within 30 days of purchase. The others don’t mention a warranty period, leaving their coverage terms unknown.

What the Numbers Mean for You

Those RPM figures aren’t just numbers on a page; they change how the tool feels in your hands. A grinder spinning at 8,500 RPM cuts through steel pipe quickly, but it can grab and kick back if you’re not ready. That’s why the Makita XAG20Z offers a dial dropping down to much lower speeds. Slower speeds let you sand wood or polish metal without burning the surface. Going faster isn’t always better when precision matters more than raw power.

The 4-1/2 inch and 5 inch disc sizes mean you can share wheels across all these tools. You don’t need to buy special blades for each one. A 5 inch disc simply gives you a slightly deeper cut into thick material.

X-Lock changes your workflow entirely. Instead of hunting for a pin spanner to loosen a nut, you just pull a lever and snap the new disc on. When you’re working overhead or in tight spaces, dropping a small wrench is a real problem. X-Lock eliminates that risk.

Safety features like AFT and electric brakes protect you when things go wrong. A wheel stopping in 2 seconds or less means you can set the tool down safely right away. Without that brake, a spinning disc stays dangerous long after you release the trigger. These features matter most when fatigue sets in late during a project.

1. XAG04Z 18V LXT® Lithium-Ion Brushless Cordless 4-1/2” / 5″ Cut-Off/Angle

Check Latest Price on Amazon

Best for: Standard brushless grinding tasks

The Makita XAG04Z serves as the baseline for Makita’s 18V LXT brushless grinders. It uses a BL Brushless Motor that eliminates carbon brushes, allowing the motor to run cooler and more efficiently for longer life. This electronically controlled motor matches torque and RPM to the changing demands of your application. It also includes Automatic Speed Change technology, which adjusts speed and torque during operation for optimum performance. For safety, it features Active Feedback-sensing Technology (AFT) that shuts the motor off if the wheel is suddenly forced to stop. The listing notes the motor optimizes battery energy use for up to 50% longer run time per charge compared to brushed models.

What makes this model stand out is the combination of AFT and automatic speed adjustment without extra manual dials. It handles the shifts between grinding and cutting on its own. However, it doesn’t list an electric brake, meaning the wheel will spin down naturally after you release the switch. It fits users who want reliable, automated power management for general fabrication work.

Pros

• Automatic Speed Change adjusts torque and speed during use
• AFT shuts off the motor if the wheel binds
• BL Brushless Motor runs cooler for longer life
• Optimizes battery energy for up to 50% longer run time per charge

Cons

• Title says Tool Only, and the box lists no battery, so that is a second purchase.

2. XAG11Z 18V LXT® Lithium-Ion Brushless Cordless 4-1/2” / 5″ Paddle

Check Latest Price on Amazon

Best for: Fast stopping with paddle switch

The Makita XAG11Z builds on the brushless platform by adding a critical safety upgrade: an electric brake. This brake stops the grinding or cut-off wheel in 2 seconds or less for maximum productivity. Like the XAG04Z, it drives the wheel at a fixed high speed through its BL Brushless Motor and includes both AFT and Automatic Speed Change technology. It also uses a paddle switch design, which requires you to hold the paddle to keep the tool running. The motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge.

The addition of the electric brake changes how you work on a busy site. You can make a cut, release the paddle, and set the tool down almost instantly without waiting for the disc to coast to a halt. This saves time over hundreds of cuts in a day. Because it locks you into a fixed 8,500 RPM, it isn’t meant for delicate polishing jobs that require lower speeds. It’s built for tradespeople who prioritize fast cycle times and drop-safe operation.

Pros

• The electric brake brings the wheel to a near-instant halt after you release the switch.
• Paddle switch adds drop safety
• Delivers a stated maximum rotational speed suited for heavy grinding.
• Includes AFT and Automatic Speed Change technology

Cons

• Listed as Tool Only, so a job needing a battery or charger is left out.

3. 18V LXT Lithium-ION BRUSHLESS Cordless 4-1/2 in. /5 in. X-Lock

Check Latest Price on Amazon

Best for: Quick X-Lock disc changes

The Makita XAG17Z brings the X-Lock mounting system to the 18V LXT lineup. This quick-change system allows for tool-free wheel changes using a simple snap-on mounting process. To remove a disc, you just use the pull release lever for change-out. It accepts both 4-1/2 inch and 5 inch wheels, keeping it compatible with standard abrasive sizes. The product data provided for this specific listing is very brief, focusing primarily on the X-Lock mechanism and mentioning Stens replacement parts.

X-Lock fundamentally changes how you manage consumables on a job site. You don’t need to carry a wrench or worry about stripping the threads on a locking nut. You just snap the disc on and pull the lever to take it off. Since the listing doesn’t detail the motor type, RPM, or safety sensors, those specifications remain unknown. This grinder isn’t for buyers who need full confirmation of electronic safety features like AFT before purchasing. It suits users whose main priority is the fastest possible disc swapping.

Pros

• X-Lock allows tool-free wheel changes
• Snap-on mounting simplifies installation
• Pull release lever makes removal fast
• Fits standard 4-1/2 inch and 5 inch discs

Cons

• No safety features like AFT mentioned in the data

4. XAG20Z 18V LXT BL 4-1/2”/ 5″ Paddle Cutoff/Angle Grinder

Check Latest Price on Amazon

Best for: Manual speed adjustment control

The Makita XAG20Z stands apart because it gives you direct control over the motor’s output. It features a variable speed control dial that allows manual RPM adjustment from 3,000 to 8,500 RPM. This lets you match the speed precisely to the application, whether you’re cutting steel or sanding wood. It keeps the core safety suite intact with AFT to shut off the motor if the wheel binds. It also includes the electric brake for rapid disc stoppage when you let go of the paddle. The BL Brushless motor eliminates carbon brushes to run cooler and more efficiently for longer life, paired with Automatic Speed Change technology.

Having a dial that drops down to much lower speeds opens up tasks that would normally burn through material at higher speeds. You can use wire wheels or flap discs without destroying the workpiece. The trade-off is that you have to remember to set the dial correctly before pulling the trigger. It’s not the right choice for someone who wants the tool to handle all speed adjustments automatically without manual input. It’s ideal for fabricators who work with mixed materials throughout the day.

Pros

• Variable speed dial adjusts from a low setting for delicate work up to full cutting speed.
• Electric brake stops the wheel in 2 seconds or less
• AFT shuts off the motor if rotation is forced to stop
• BL Brushless motor runs cooler and more efficiently

Cons

• Variable speed control dial allows Manual RPM adjustment (3, 000-8, 500), so a fixed-speed routine is off the table.

5. DGA517Z 18V Li-Ion LXT Brushless 125mm Angle Grinder

Check Latest Price on Amazon

Best for: Extended warranty coverage

The Makita DGA517Z focuses heavily on protection, both for the user and the tool itself. It features a brushless motor paired with an anti-restart function to prevent accidental startups.

6. XAG26Z 18V LXT® Lithium-Ion Brushless Cordless 4-1/2” / 5″ Paddle

Check Latest Price on Amazon

Best for: Combined X-Lock and safety tech

The Makita XAG26Z merges the X-Lock quick change system with Makita’s full suite of electronic protections. It delivers 8,500 RPM through its BL Brushless Motor, which eliminates carbon brushes for cooler operation. The X-LOCK system allows for tool-free wheel changes with snap-on mounting and a pull release lever. It includes AFT to turn the motor off if the wheel is forced to stop suddenly. An electric brake halts the grinding or cut-off wheel almost instantly upon trigger release. It also uses Automatic Speed Change technology to adjust speed and torque during operation.

By combining X-Lock with an electric brake and AFT, this model removes nearly every friction point in daily grinding. You change discs without tools, and the tool stops almost instantly when you release the paddle. The motor manages its own speed and torque as the load changes. Because it runs at a single fixed speed, it doesn’t offer the low-speed flexibility of a variable dial model. It’s the strongest pick for structural steel workers who swap cutting and grinding discs constantly.

Pros

• X-LOCK system enables tool-free wheel changes
• Electric brake stops the wheel in 2 seconds or less
• Delivers a stated 8,500 RPM
• Includes AFT and Automatic Speed Change technology

Cons

• A fixed top speed means it lacks variable speed options.

Check Latest Price on Amazon

Best for: Simple compact handling

The Makita DGA452Z relies on a traditional four-pole motor design rather than the newer brushless systems seen in most other models here. It features an easy grip body aimed at comfortable handling during use. Safety is addressed through an anti-reset function equipped with a warning light. It also includes an Electronic Current Limiter to protect the motor from drawing too much power under heavy loads. The listing keeps the details focused on physical handling and basic circuit protection.

A four-pole motor represents an older generation of tool design compared to the brushless models in this lineup. The easy grip body helps reduce fatigue, especially when working overhead or in tight corners. The warning light for the anti-reset function gives you a visual cue about the tool’s status. Because it uses a brushed motor, it will eventually require carbon brush replacements. It isn’t for users who want the longer run times and cooler operation of a brushless motor. It fits someone who prefers a straightforward, proven motor design with basic electronic protection.

Pros

• Easy grip body improves handling comfort
• Anti-reset function includes a visual warning light
• Electronic Current Limiter provides overload protection
• Four-pole motor offers a traditional design

Cons

• Uses a four-pole motor instead of brushless technology
• Doesn’t list RPM or advanced safety sensors like AFT

Beyond the main ten, three other models deserve a brief look. The XAG16Z 4-1/2”/ 5″ Cut-Off/Angle Grinder carries the 18V LXT BL designation, indicating a brushless motor in a standard cutoff format. The DGA513Z LXT Brushless Angle Grinder also specifies a 125mm brushless setup sold without batteries or a charger. Finally, the BGA452Z Cordless 4-1/2″ Cut-Off/Angle Grinder rounds out the alternatives as a tool-only option in the 18V LXT Lithium-Ion family.

If you’re still weighing which safety features matter most for angle grinders, reading about Makita’s Active Feedback-sensing Technology directly from the manufacturer explains exactly how the sensor detects binding and cuts the power. Understanding how AFT interacts with the motor helps clarify why some cordless 18V Makita angle grinders list it alongside an electric brake while others rely on just one system.

The Makita XAG26Z wins on the axis that matters most by combining X-Lock, AFT, and an electric brake into one tool. For a reader who isn’t sure which features they care about yet, the Makita XAG04Z is the safer starting point because it balances automatic speed control and core safety without overwhelming complexity. Your next step is to check your current 18V battery inventory and click through to see today’s availability for the model that fits your work.

Frequently Asked Questions

Is a higher RPM always better for an angle grinder?

No, a higher RPM isn’t always better. While 8,500 RPM cuts thick steel quickly, it can burn wood or melt plastic. Models like the Makita XAG20Z include a variable speed dial for delicate tasks. Match the speed to your material to avoid damaging workpieces and wearing out discs faster than necessary.

What does “Tool Only” actually mean in the listing?

“Tool Only” means the box contains just the bare grinder, without an 18V battery or charger. You must already own compatible Makita 18V LXT batteries or buy them separately. This prevents paying for extras you don’t need. Always check your battery inventory before ordering. The third-party Heimerdinger model lists compatible battery numbers to help verify fitment.

How do I compare 125mm and 5-inch disc sizes?

You don’t need to convert them because they refer to the same physical size. 125mm is simply the metric measurement for a 5-inch disc. The Makita DGA517Z lists 125mm, while American models list 4-1/2 inch or 5 inch. Both sizes fit these grinders, as the guard accommodates the slight difference. They’re identical in capacity.

Does a missing specification mean the tool lacks that feature?

Not necessarily. If a listing doesn’t mention an electric brake or a specific RPM, the seller simply didn’t include that detail in the text. It doesn’t prove the feature is absent from the tool. For example, the Makita DGA511Z listing provides almost no technical details, but the tool still functions within the 18V system. Compare models based on facts printed in the product data.

Conclusion

Picking the right grinder isn’t just about what’s in the box today. It’s about how it’ll hold up when you’re tired and rushing a cut. Grab whichever model fits your hands best, pair it with fresh batteries, and start practicing on scrap metal before your next real project.
