Review on 🛠️ CO Z Titanium Drilling Cutting Electrical Tool by Jennifer Roberts

Good day, dear readers of ! When a couple of years ago I needed to purchase several drills of different diameters, then in the store I came across a drill that I had long wanted to have, but somehow it didn’t work out. This drill is conical, stepped, with a drilling diameter of 4 to 12 millimeters. I have used this drill before and really liked it. The drill perfectly drills thin steel or non-ferrous metal, as well as softer materials - plastic, fluoroplastic and other similar ones. Manufacturer - Zubr. I really like the products of this brand, as they are usually of excellent quality and at a price that suits me quite well. The drill has a cobalt coating, which allows to extend the life of the drill by 15-20%. Unlike similar drills with a large number of drilling sizes. I like this because the drilling depth of one size is about 8 millimeters, so you can easily drill fairly thick plastic or aluminum with the right size. And it's very convenient! By the way, this picture was taken with a Nikon lens. The drill has two cutting edges. In the gaps between the cutters on one side there is a BISON marking and the steel grade from which the drill is made is indicated and on the other hand, the dimensions of the drill are indicated. Very comfortably! The drill has 5 steps, with a diameter of 4.6, 8,10,12 mm. For me, it's enough. The drill bit has a 1/4" hex shank, perfect for quick installation in an adapter for a screwdriver. The cruciform sharpening of the cutting edge makes it possible to work without preliminary punching and eliminates the possibility of wedging. The sharpening angle at the top is 135 degrees. With this drill, of course. I don’t use it often, but I think that in a home workshop (or in a garage, or in a country house - depending on where you make everything), there should be such a drill, as well as many other drills and tools in general. After all, these are adult toys! And I recommend this drill and put 5 stars! The cost of the drill is 320 rubles.
