Review on 🔧 Neiko 10169A Titanium Automatic 5 Piece: Premium Durability for Efficient Performance by Jay Williams

I have some better step drills but I need a larger diameter drill. I drill plastic sheeting a lot so can't really comment on the durability but I don't expect them to last too long when drilling steel. Good step drills cost $20 to $50 each. My biggest complaint is that the length of each step on the 32nd exercise is a bit short. I have very similar parts that I bought from home stores (Milwaukee and Irwin brands) and the steps seem to be about 1/16 inch longer. Contact with the material as the selection step is punched through. I only leave a slight scar on my head, but I don't have this problem with longer bits. Я сверлю ручной дрелью, но если бы я использовал сверлильный станок, я, вероятно, мог бы установить свои упоры, чтобы предотвратить это.Единственное, чего я не видел, - это максимальная толщина материала для каждого сверла.Жаль, что я не наткнулся на That.
