From this point of view, the relationship between u-drill and ordinary hard drill is almost the same as that between machine clamp turning tool and welding turning tool. After the u-drill is worn, the blade can be replaced directly without regrinding. After all, the use of indexable blade is still less material than the whole hard drill, and the consistency of blade is easier to control the size of parts. So, u drill is a good choice for you!
