Probably the only safety post I’ll write

Like all power tools, the Dremel rotary comes with a plethora of safety warnings. Like it happens in a vast majority of cases, enthusiastic new owners will completely ignore all of them. Here’s one you should pay attention to – eye protection.

The tool can spin up to 35,000rpm while cutting into wood, plastic or metal. Things – small, sharp things, to be precise – tend to fly in all directions. (Well, not really – they fly mostly perpendicularly to the axis of rotation and in the plane of the spinning accessory, but saying it like that rather ruins the expression. Did I mention I am a scientist?) Anyway, things tend to fly around, often in the exact plane where your eyes are located, especially if you happen to be looking at what you are doing. The flying bits can come from the material you are working on, or from the accessory you are using, or both. Some accessories can actually slowly disintegrate without being applied to a material at all – one example are the abrasive buffs, which are essentially spinning sponges. As they spin, even at their indicated max speed of 15,000rpm, they slowly shed the fibres they are made up of. Hopefully, you’ll never make the mistake of running them at a higher speed.

Safety goggles are cheap – I picked up a pair for ~€3.50 after feeling multiple bits of debris hit my face and realizing that continuing to work without eye protection would be simply dumb and inexcusable.

Don’t be a hero!
