Recently I picked up this TACKLIFE multi-function rotary tool. I have been using a rotary tool for many years. I have had a Dremel for over 20 years and it helped me with many great projects. This new one from TACKLIFE comes in a carrying hard case. The build quality is very good and feels solid. There are an assortment of accessories which they have included. This includes a flexible shaft, side handle for extra grip, and a guide for cutting drywall. You also get a box of cutting wheels, saw all drill bits, sanding disk, grinding stone, and tool.
The speed is variable and an easy adjust rotary knob. The chuck has a locking button so you can quickly install and remove different bits. The overall design allows for a comfortable grip when working on your project.
