45+ years in the trade I've used Pretty much all the types and the Makita 9005b was my favorite. I would also use a 7inch 5/32"disc with a made up 7inch 120degree guards. Just like store bought when built properly. 120degree guards at that time were legal via OHS for pipe. 180degree Guards grinding on pipe are downright dangerous. Always changed out the 6ft cord for a 15foot. I worked a lot on big inch pipe. The grinders stood up quite well. I had 6 on my truck at all times. never had to fix any in the field. Owned 15 in all states of repair and would once a year spend 2 days fixing and repairing. Switches, brushes, and cords would be the main fix
*You wanna know who makes the best angle grinder? Ask a Welder. They use them DAILY and they've torture tested just about every brand imaginable..(25 year RR Welder here).* *For the record, Makita still makes the 9005B...And I agree, it's the best Angle Grinder money can buy. They cost more but you'll probably buy only One of them in your whole life..It's like buying a Toyota Camry. You better love it because you're probably going to be driving it forever*
Cool le 9005b je l'ai de chez Descimco, il voulait le jeter, je l'ai garder et depuis 15 ans qu'il fonctionne plus la vie en travaux d'usine qu'il avait déjà vécu 🤣🤣🤣 nice review dude 🤘
Great insightful personal review. I have not been able to find a review/comparison of 7”/9” grinders. Makita, DeWalt, Rigid, and Milwaukee all have 15 amps around the 4 HP; DeWalt has one at 5+ HP. I work mainly with concrete and am not clear on what makes the ones advertised for that specific application so expensive. A video covering that size range, the relationship between HP to amps, and the difference between metal vs concrete applications would be a huge help.
Hi max, relationship between HP to amp is a good question indeed. For welding specifically, 7" and 9" grinder are rarely used, so I cannot help you with that. For a 5" like the 9005B in the video, what make it so tough is not just the amp rating, but also the faster speed. The 1000RPM extra on top really help to give HP for hardcore grinding. Like any engine, you get more torque at hi speed. On top of that, it gets a better cooling since more air is flowing through. If I can help you to choose a big grinder for your task, I can say that the Ridgid 7" is not that tough. I had it fix after 1 year of light use. It was the carbon brush holder that melt away. They must have been made out of material that does not like heat. For the makita's the brush holder are made of bakerlite. A brittle heat-resistant material. Stick welding handle are made of that too. By the way, the repair on my ridgid was free. Lifetime guarantee.
1:10 "I don't know how they can not go bankrupt .... if a company were start buying a bunch of Ridgid and replace them every time they break." To be clear most companies that offer Lifetime warranties don't cover "professional use" and professionals & businesses want tools that keep working not ones that paid employees have to spend time getting replaced. Ridgid won't even call it a "warranty" because that would give you certain legal rights that are a financial liability for them, instead it is a "Lifetime Service Agreement" that they can deny at their discretion.

You can still buy the 9005B in Canada. One of the best selling Makita grinders still.

Manufacturers are very smart. They dangle life time warranty as a major selling point, knowing that most customers never file for it.
🙌thank you for this review
