I've been using my Chicago brand rotary tool for a project requiring sanding. After a while there started to be a grinding noise from the motor. Like something gritty was in the motor. I assumed it was a build up of saw dust in the casing around the motor so I would blow the dust out and the noise would stop. I thought the problem was solved. Eventually it got to a point where blowing the vents out didn't help. I was worried I'd burn out the motor if I didn't fix it. I unplugged it (safety first!) and opened the casing. As I suspected there was some build up inside the tool. I proceeded to blow it out as well as I could. Once back together I turned it on. The grinding noise is gone but the motor's general sound it makes has changed. It's higher pitched then before. Not really a whine but definitely different then it was before. I'm not sure what I did wrong. Nothing was moved when I had it opened. The best help I could find online said that it may need oiled, but it sounded normal before I opened it (besides the grinding noise). Does anyone know what it might be?
What's that you say, I'm clogging up the Tool Review forum? You're only saying that because you already have this tool, or you're depressed that you don't. Write up: What’s 1.9kgs, brushless, and eats concrete for breakfast? If you said an M18 Milwaukee rotary hammer drill, you’d be close. But at this size and weight, it could only be the M12 FUEL 2416-20 - Rotary Hammer. It looks small enough to give to your kids for christmas (which would be an awesome gift by the way, just don’t provide any bits). While this may be the most portable rotary hammer drill known to mankind, it still packs a mighty punch. Official specs: 6mm holes in concrete; stealing candy from a baby.10mm dynabolt holes in clay bricks; arm-wrestling your 4 year old niece.12mm holes in concrete; not as fun as above mentioned activities, but still pretty easy.Easy to throw to colleagues on above floorRedOther useful stats: Max Capacity : 5/8"Blows per minute : 0 - 6200BPMSpeed : 0 - 900 RPMWeight : 3.9 ;bsLength : 10"On-tool fuel guageWe only wish it had a belt hook. Also, it has no stubby holder. We recommend getting some 4.0ah batteries with this unit. Despite being brushless, you are asking it to put holes in concete, which is traditionally a substance that resists damage fairly well. With a street price of (insert US pricing here), if you have the M12 line and need to put in anchors regularly, this is a no-brainer. Seriously, stop reading this rubbish and go buy it, it’s amazing.
