With cheap drill blades it is difficult for the center to come out and it takes time to cut, but the Nazi product has a sense of security for work. Since it is a consumable item, it is grateful to have a cheapest setting.
Although it purchased as a spare, the current product has changed package design and the drill main body has become silver color of the material from the black film finish. Because it is silver, it is easy to align colors as replenishment when the drill set item is missing. Although it is a major manufacturer, two sets of items are fulfilling and the price is also cheap. Less than 3 mm has a shorter lifespan, so quality good or bad clearly comes out so domestic manufacturers products are safe.
