Review on Dremel 4250-35 engraver in a bag, 175 W by Wiktor Franko ᠌

A good tool for fine work when you need to cut a thin sheet of metal or grind, with soft materials you can use cutters. With its pros: Sufficient power for work. No need to charge the battery if you suddenly need to do work. A convenient speed controller is protected by glass from chips getting inside (unlike the model with a slide controller). Its cons: 1. It's a pity that the motor is not brushless. 2. I often notice with such dremels that the knurling and edges are licked on the clamping nut, I thought what the problem was and then I realized that since the nut has a thread undercut at the end, the shaft rests against it with the threaded part and the collet cannot be fully tightened. flat and turning on the rotation of the shaft at the beginning, he turned 1.5-2 mm of thread entry (under the cylinder), and at the same time with liquid lubricant, he rubbed the thread on the nut and then bought a new one.
