Question: is it a verable speed
Document: Looked for three months to fins a good value air buffer. this tool Is fantastic.Light, powerful, fully adjustable speed cant say enough
i've tried air buffers in the past and had these complaints, bulky, touchy trigger switch, noisy and hate having the heavy hose hanging off my shoulder. Neiko seems to have overcome some of these issues. This buffer is super lightweight, starts up slowly and revs up smoothly. I still hate the hose issues, but bought a short lightweight hose and connected it directly to the buffer, eliminating the coupling and losing the bulky hose.
Works very well and didn't cost a fortune..I would recommend..Works just great for what I needed..quick buffing in tight spots..
Works excellently and is easy to use. Buffs and polishes just as it was advertised. Prompt delivery. I would highly recommend this tool.
This is and excellent product for the money. We use this for commercial use in our body shop and the guys like ti very much.
This buffer really exceeded my expectations. It performs better than some buffers we use at our business that cost 3-4 times as much! I will be buying more!
The Neiko polisher is not expensive and runs great for the money. I needed a polisher that was lighter than my electric buffer because of arm pain. I use it on my boat. It has plenty of power. I would recommend.
Nothing else to say. Plenty powerful. I use it with a high density wire-wheel brush to clean heavy rust and corrosion off of steel wheels at a Houston shipyard and it never misses a beat. My previous buffer would bog down and even stop if I applied too much downward pressure but this thing just chews it up. Feels/looks well put together and runs like a beast.
I would have given this 5 stars if it came with a C shaped handle as well.I've only used this thing briefly so I cannot comment on it's longevity but it feels like it's made well.It isn't loud and doesn't vibrate much at all.I'm pretty sure this isn't meant for grinding wheels but I slapped one on to test it and it did OK. I was able to bog it down a little but only when pushing hard.
I use this with a 7 inch diamond cup wheel to grind, trim and profile concrete, with using only about 50-60 lbs of air makes a very controllable grinder. This will grind cured concrete like a 7 inch electric angle grinder with a 24G disc will grind body filler. Has a long lever on the air throttle valve, works real well for feathering RPM for sensitive work. I couldn't be happier with it.
Answer: no
