The angle grinder side handle gives you a second grip point, so you can hold the tool with both hands and keep it under control. It helps you resist the twisting force of the motor, steer the wheel through the cut, and stay steady if the wheel snags. Fit it before every job, tighten it fully, and do not use a grinder whose handle is missing, cracked, or loose.
Quick Answer
Fit the side handle before you plug in or insert the battery, screw it in fully, and hold the grinder with both hands. Put it on the side that keeps your wrists straight and your body out of the wheel’s plane. Do not use a grinder with a missing, cracked, or loose handle.
Key Takeaways
- The side handle gives your second hand a fixed grip, so you can resist torque and a sudden grab by the wheel.
- It does not remove kickback risk. You still need the guard, the right wheel, and a secured workpiece.
- Choose the mounting position that suits the job and your dominant hand, and tighten it fully each time.
- Inspect the handle for cracks, stripped threads, and play before every use.
What Does the Angle Grinder Side Handle Do?
An angle grinder spins a wheel at thousands of revolutions per minute. The main handle holds the switch, but it gives you little leverage. The side handle is a threaded bar or grip that screws into the gear head, giving your other hand a firm hold well away from the wheel.
With both hands on the tool you can:
- Resist the torque that tries to twist the grinder when the wheel bites.
- Keep the tool steady on contours, corners, and uneven surfaces.
- Keep your hands apart and clear of the wheel and the spark stream.
- Cut and grind for longer without gripping the main handle as hard.
Safety Benefits of Using the Side Handle
Most grinder manuals tell you to use the supplied handle and hold the tool with both hands. The reasons are practical:
- Better kickback control. Kickback happens when a wheel pinches or snags and the grinder jumps. A second hand on the handle lets you brace against that reaction. It lowers the risk but cannot stop it. See our kickback causes and prevention guide.
- Fewer slips. A one-handed grip can slide off the body when the grinder vibrates or the wheel grabs.
- Safer hand placement. The handle keeps your off hand out of the line of a broken wheel and away from the guard opening.

How the Side Handle Improves Control and Comfort
Holding the grinder with two hands spreads its weight and the reaction forces between both arms. You steer with the side handle and use the main handle for the switch and push. That makes straight cuts and weld blending easier. For stance and grip, see how to hold an angle grinder for control.
Vibration is also easier to manage. Hand-arm vibration from power tools can cause long-term health problems, and the UK Health and Safety Executive publishes guidance on hand-arm vibration for employers and workers. Some grinders ship with an anti-vibration side handle. Check your manual to see whether yours does, and use that handle rather than a generic one.
How to Install and Position the Side Handle
- Disconnect power. Unplug the grinder or remove the battery.
- Pick a mounting hole. Most grinders have threaded holes on both sides of the gear head, and many have one on top. Check your manual for the positions your model allows.
- Screw the handle in by hand, then snug it with the tool the manufacturer specifies, if any. It should not wobble.
- Match the position to the job. See the table below.
- Check the guard. The handle should not touch the guard, and the guard should stay between you and the wheel.
- Test the grip. Hold the grinder in your working stance and confirm that your wrists are straight and you can reach the switch.
| Position | Typically used for |
|---|---|
| Left side | General grinding and cutting for right-handed users |
| Right side | Left-handed users, or when a left-side handle would put your hand in the spark path |
| Top (if provided) | Surface work with a flat or cup wheel, or tight spaces, as your manual allows |
These are common starting points, not rules. Your grinder manual and the task decide the best position, and you should always keep your body out of the plane of the wheel. If you are choosing between switch styles at the same time, see paddle vs. slide switch angle grinders.
Side Handle Mistakes to Avoid
- Running the grinder without the handle because it is in the way.
- Using a handle from another brand or model that has a different thread or length.
- Leaving the handle loose or cross-threaded.
- Gripping the handle so hard that your hand and wrist tire quickly.
- Letting the handle sit where it blocks the guard or your view of the cut.
- Continuing to use a handle with cracks, bends, or damaged rubber.
Side Handle Inspection and Maintenance
Check the handle before each use, along with the guard and wheel. Our pre-use inspection checklist covers the full list. For the handle specifically:
- Look for cracks, bent bars, and stripped threads.
- Confirm it threads in fully and does not move under hand pressure.
- Wipe off dust and oil so your grip does not slip.
- Replace a damaged handle with a part approved for your model.
The handle is one of several angle grinder parts that affect safety. OSHA’s Safe Use of Portable and Hand-Held Power Tools fact sheet adds that abrasive wheels must be inspected before mounting and that you should never stand in the wheel’s plane of rotation.
Frequently Asked Questions
Do all angle grinders need a side handle?
Almost all angle grinders are designed to be used with a side handle, and most ship with one. Use the handle your manufacturer supplies, and hold the tool with both hands unless your manual says otherwise for a specific task.
Which side should the angle grinder side handle go on?
Right-handed users usually start with the handle on the left, and left-handed users on the right. The best side keeps your wrists straight, keeps your hand out of the spark stream, and keeps your body out of the wheel’s plane. Follow your manual for the allowed positions.
Can I use an angle grinder without the side handle?
You should not. Without it you have less control over torque and kickback, and it is easier to lose your grip. If the handle is damaged or missing, replace it before using the grinder.
Can I use a side handle from a different grinder?
Only if the manufacturer says it fits your model. Handles from other brands can have different threads or lengths and may loosen or fail to seat. Use a part approved for your grinder.
Does a side handle stop kickback?
No. It helps you control the tool when a wheel snags, which lowers the risk of injury, but kickback is prevented by the right wheel, a secured workpiece, a correct guard, and good technique.
Conclusion
The side handle is a small part with a big effect on control and safety. Fit it before each job, tighten it, keep it in good condition, and use both hands. For the rest of your setup, work through the angle grinder PPE guide before you start.
