Chicago Pneumatic 8941075452 Cp7545B Angle Grinder, 4.5", 3 Piece

Little bit pricey but good tools usually are. Got the CP for adjustable guard w/o taking apart. Our shop is very OSHA compliant and you don’t want to get caught without a guard on grinder. Keep in mind this is a rear discharge so use the included muffler hose so not to get oiled shot back on you. I made a pigtail that sticks out a little bit past muffler.

Outil bien conçu et puissant, demande un compresseur d’au moins 7.5 cv. Les ingénieurs ne se sont pas trop forcés, y’ aurait pu rajouter un bloqueur d’arbre, pour le prix c’est ordinaire, les modèles électriques l’ont presque tous ! Consolation, il y a un guard à rotation rapide, merci C.P.

Rated at 840 watts and truly feels like it, even with a swivel air inlet. Lots of power. Good handle ergonomics and rubber grip, perfect size diameter. Air inlet rotates continuously 360. Pretty lightweight. Very noisy, but so what. Wear your earplugs. Some no load vibration at high RPM, minimal. No shaft lock button, need to use wrenches. Best all around air angle grinder for my purposes; heavy duty aluminum fabrication and welding.

Blade won't spin. I have to spin it on its own to get it to start going which is ridiculous. Once spinning it does its job but sometimes when you stop then try to start again it does nothing.

Excellent grinder. Not that loud either, which is a bonus for any grinder that's air powered. The speed governing of the grinder works well too, no over-speeding at all.
