Description

Angle grinders are indispensable for a variety of jobs done around the house. From cleaning grout to clearing rust to cutting tile, nothing other than an angle grinder (or an expensive contractor) will get these difficult jobs completed. To perform these tasks to the best of your ability, you need the freedom to get into any of tight spaces. The Ryobi P421, with its rotating pistol grip and adjustable side handle, is the grinder for the job. It is ready right out of the box with an included grinding disc and spanner so you can replace it as soon as it wears down. It is compatible with the Ryobi One+ lithium ion batteries and the older NiCad models, so if you already have any Ryobi tools, you can use this one, too. Handle this in most any condition with the rubberized grip. With Ryobi and the trusted One+ battery system, you simply cannot go wrong.

  • Great machine!!!
Aside the fact that I'm a Ryobi fan, this product is wonderful. First of all it has the proper weight for you to "feel it", but without being heavy after some hours of work. Very good design (one of the few tools I see that the toolkey is hidden in the side handle, making it easy to find). Safety trigger lock, three different positions for the lateral handle and no wires... It's a win! ... show more

  • Amazing
The angle grinder is very powerful and works flawlessly. It is hard to beat for the price.

  • Solid for light duty tasks
I'm returning this for its more powerful brother but it works fine. Was able to cut off a Master padlock in about seven seconds with a cheap cut-off wheel and it generally cut cattle panels faster than a reciprocating saw but binds up if the wire is under some tension. That may just be the 10 year old P102 batteries? But for light duty work around the house no worries. ... show more
