An angle grinder power tool is a diverse tool that is handy to have in your tool box. It is used to surface grind metal, prep for welding, cut metal, cut tile, grind concrete and stone, polish materials, power carve wood and the list goes on. When I use an angle grinder, it is rarely convenient to a power outlet. Often times it’s a situation where you bring your own power. 🙂 Having a good angle grinder that is cordless is super convenient, but not if it can’t perform. Ridgid has added a 4 1/2″ brushless angle grinder to their line up of Octane powered 18V power tools and I’m excited to check out how it performs.
First of all, why Octane and Octane with Bluetooth?
The Octane battery cells are supposed to give you faster startup speeds and increased performance because the battery and tool ‘talk’ and respond to each other and the situations they are in. It has a chip that constantly monitors temperature, voltage and current. The bluetooth feature can give you performance notifications on your phone if you install the Ridgid App. It can also locate, lock/unlock batteries if your phone is within range of the battery.
Tool Review – 18V Ridgid Angle Grinder
18V Ridgid Angle Grinder Performance
- The 18v 4 1/2″ angle grinder has a high power output with 10,000 RPM, just under the 8 amp corded model at 11,000 RPM. It is best in class for cordless 4 1/2″ angle grinders. So far plenty of power for my uses and more convenient being cordless.
- The 18v angle grinder has a LED light overload indicator at the bottom of the handle.
- The ON switch has ‘lock on’ capability, however if you take out and replace your battery with it ‘locked on’, it won’t automatically turn back on unless switched off and back on…for safety of course!
Ergonomics
- The necked down handle is a comfortable size to grip, and the hex grip on the handle is nice to reduce hand slipping.
- There are 3 auxiliary handle positions to make it comfortable and safe to cut at different angles and hand preference.
- The tool guard position can be rotated without an extra tool, which is really convenient.
The Ridgid 18v 4 1/2″ angle grinder runs for $119 at Home Depot for the bare tool only. It comes with a spanner wrench (to change the wheel), a grinding wheel, an auxiliary handle, and an operator’s manual.
The Verdict
I find the 18v octane Ridgid angle grinder very comfortable and convenient. It has plenty of power for my needs. The run time depends on your battery size, so the bigger the better in my opinion. The spanner wrench has on board storing location in the handle, so I won’t loose it. 🙂 I can definitely recommend this tool, especially with the lifetime service agreement if you register it within 90 days of purchase.
However, right now Home Depot is running a deal, if you buy a Ridgid 18V octane battery starter kit for $179. You get the Ridgid angle grinder for FREE!
