- 13 amp motor
- 2,800 to 10,500 RPM

The Makita 9564CV is a corded 4-1/2-inch grinder with a stated speed range of 2,800 to 10,500 RPM. Its dial helps you match wheel speed to the application, while constant speed control is designed to add motor power under load to maintain speed.
Soft start suppresses the reaction at startup, and Makita’s SJS mechanical clutch allows the drive shaft to slip if a wheel is forced to stop. The included set has a grinding wheel, tool-less guard, side handle, inner flange, lock nut and wrench.
Pick this model if you want a corded grinder with a dial and a 4-1/2-inch wheel. Skip it if a cord will restrict movement around your work area.

The variable speed control adjusts wheel speed, and the anti-rotation system senses tool rotation and shuts the grinder down if the motion is excessive. It accepts 4-1/2-inch to 5-inch wheels.

- 13 amp corded motor
- 5 in wheel

FLEX LE 14-11 125 Variable Speed Grinder: Best for broad speed adjustment
- 12 amp corded motor
- 2,800 to 11,500 RPM
- Anti-kickback shutdown

How do you choose a variable speed angle grinder?
Choose a variable speed angle grinder by matching its power source, wheel size and speed range to the work you plan to do. A high maximum speed alone doesn't show whether the grinder suits your wheel or task.
Start with wheel size and the accessories you plan to use. These picks take 4-1/2-inch, 5-inch or both sizes; check the grinder and wheel manuals for compatible sizes and speed limits before buying.
Then choose corded or cordless power. Corded grinders suit a fixed work area with convenient outlets, while cordless models make it easier to move without managing an extension cord.
The DEWALT cordless models are tool only, so factor in a compatible battery and charger. If you already own batteries, confirm the platform before making the comparison.
Compare how speed is controlled, not just the highest RPM. A dial or multiple settings gives you a choice of speeds, while some models here provide a maximum speed without a full range.
Also consider the switch and the safety features you want. A brake, anti-kickback shutdown, anti-rotation system and mechanical clutch serve different roles, so read the tool manual and compare the function each model offers.
When does variable speed help, and when can you skip it?
Variable speed is useful when the task or accessory calls for a different wheel speed from the grinder’s maximum. It gives you more adjustment, but doesn't make an incompatible wheel safe to use.
It can be helpful for buyers who switch between grinding, polishing and other jobs that benefit from different speeds. The Makita and FLEX models publish broad ranges, while Milwaukee’s cordless grinders provide five defined settings and the Metabo HPT offers six modes.
You can skip variable speed if you only perform one kind of work and a fixed-speed grinder already suits the wheel and task. In that case, focus on the correct wheel size, power source, handle and guard rather than paying attention to speed options alone.
Before selecting a speed, check the wheel’s maximum rated RPM and instructions. Keep the wheel within its limits and the grinder’s approved settings.
How should you set up a variable speed grinder?
Set up the grinder with the correct wheel, a secure guard and a stable work area before connecting power or inserting a battery. Keep the tool off while you check the accessories and controls.
Confirm that the wheel type and size match the job and grinder. For a refresher on common cutting, grinding and flap options, see our guide to angle grinder disc types.
Fit and position the guard between you and the wheel’s likely path. Install the side handle where it supports a firm two-handed grip, then check that the wheel is seated and secured according to the manual.
Set the speed before starting, using the wheel maker’s guidance and the grinder’s instructions. Hold the grinder firmly, keep bystanders clear, and let the wheel reach operating speed before bringing it to the work.
What mistakes should you avoid with a variable speed grinder?
The most common mistakes are choosing a speed without checking the wheel, removing the guard, and forcing the wheel into the work. A variable speed control does not cancel the need for the right accessory and safe handling.
Don't assume every wheel fits every grinder or material. Confirm its size, purpose and maximum speed, and replace it if it is cracked, damaged or unsuitable.
Don't treat a brake or anti-kickback feature as a substitute for control. Maintain a secure grip, keep the guard in place and avoid twisting or pinching the wheel in the cut.
Avoid pressing hard to make the grinder work faster. Let the correct wheel do the work, maintain a steady posture and stop if the tool behaves unexpectedly.
How do you care for and store a variable speed angle grinder?
Keep the grinder clean, inspect its accessories and store it so the cord, guard and wheel are not damaged. Follow the maker’s maintenance steps for the specific model.
After the tool is off and the wheel has stopped, remove dust from the outside and inspect the guard, handle and power cord or battery connection. Check accessories for cracks, chips or wear before each job.
Store wheels flat and dry where they won't be struck or bent. Keep the grinder dry, protect it from dust when stored, and follow the manual for any model-specific cleaning or service.
What safety features matter on a variable speed grinder?
Safety features can support control, but they don't replace the guard, correct wheel or protective gear. Match the wheel to the grinder and task, and follow the tool and wheel instructions.
Some picks include a brake that slows the wheel after shutdown, while others have anti-kickback or anti-rotation features. These terms describe different functions, so compare what each model provides instead of assuming they mean the same thing.
Switch style also matters for comfortable operation. Paddle and slide switches feel different, so choose controls you can operate while maintaining a secure grip.
Before work, check that the guard is installed and positioned between you and the wheel. Read our angle grinder safety guide for details on guards, protective gear and kickback.
Which variable speed angle grinder is the best fit?
Choose the DEWALT DCG410VSB if you want cordless 20V MAX power, adjustable speed and a paddle switch. Pick the Makita 9564CV for a corded 4-1/2-inch grinder with a broad range, or the Milwaukee 2889-20 if you want five speed settings and a quick wheel stop.
For corded 5-inch work, compare the Makita 9565CV, DEWALT DWE43231VS and Metabo HPT G13VE2 by their speed controls and safety features. Before buying, match the wheel to the grinder and task, then use our angle grinder parts guide to identify the guard, handle and spindle lock.
How we scored these variable speed angle grinders
Our scores reflect how each grinder’s documented features match the needs of a variable speed buyer, including power source, wheel options, adjustment and control features. We compared the stated details for each model.
Higher scores go to models with a strong mix of relevant features and a clearly described speed setup. A lower score may reflect a narrower feature set or less detail about speed control, rather than a poor fit for every buyer.
Frequently asked questions about variable speed angle grinders
What is a variable speed angle grinder?
A variable speed angle grinder lets you adjust wheel speed instead of running at one fixed speed. That can help match the tool to a task, but the wheel must still be rated for the grinder and intended speed.
Check the wheel instructions before adjusting speed.
Is a cordless variable speed grinder powerful enough?
A cordless variable speed grinder can suit work where freedom from a cord matters. The DEWALT DCG410VSB and DCG411VSB are rated for up to 1,640 MWO and 9,000 RPM, and use DEWALT 20V MAX batteries.
Both are tool-only options, so account for a compatible battery and charger.
Should I choose a paddle switch or a slide switch?
Choose the switch style you can operate comfortably while holding the grinder securely. This group includes paddle-switch models from DEWALT and Milwaukee, plus slide-switch models from DEWALT, Makita and FLEX.
The switch alone doesn't decide whether the grinder suits your task.
What grinder speed should I use?
Use the speed recommended for the wheel and task, and stay within the grinder’s stated range. A variable speed dial gives you a way to adjust the wheel, but it doesn't make every wheel suitable for every material.
Read the wheel instructions and grinder manual before use.
