Review on 💪 Dynabrade 51700 Straight Line Pencil Grinder: Powerful Precision Grinding for Professional Results by Mike Carter

Why so expensive? Because it is a precise instrument. It turns very quickly and the chuck and components have to be micro-machined to avoid wobbling. It's made in the USA. It's super light. Not only is it good for sanding, but it can be used for cutting, buffing, sanding, etc. if you have the right attachment. You can use any 1/8th bit so you can use any dremel bits (which are rated for 60,000rpm+) which I do it's twice the speed of a dremel so not all bits can be sure it is much more powerful than any electric coffee grinder, you can press it harder and longer and it is lighter, so if you use this type of tool a lot in your work, it is worth choosing a model with pneumatic A to acquire drive. It doesn't take much air, but more than a nail gun. A tank with a large reservoir will work well. Despite being a small tool, it requires a fairly constant flow to produce maximum performance, which is the whole point of buying an air version tool like this. You can use it in queues with a standard double hotdog, but using it with one for a long time will cause it to constantly run out of energy. A good way to test is to blow out your garage with an air gun. Notice how the air pressure drops rapidly until the compressor catches up. This is a similar use of air.
