I often have to drill holes in plastic. With a standard drill, even at the lowest speeds, the plastic tends to melt and then stick to the drill, making the hole larger than desired, not to mention fouling the drill. The hand drill is the solution, and this product offers a wide range of bit sizes, from ultra small to the sizes you'll find in a standard drill bit set. I thought it would be more difficult to operate the device, but it's actually quite simple, and I immediately started making tiny holes in the plastic wrap with no difficulty. The whole set is simply scattered in different plastic bags (with a case for storing a group of bits), and the vise design itself is inexpensive, but with all this, the set works perfectly, the drills are even. , and this kit is a very inexpensive starter kit.
