The thin shaft on these bits allows them to penetrate into depths, but they aren't designed as well as deep drills for such a task. Use water when Drilling. Drill bits are very different than burrs. Drill bits put a hole in things. Burrs carve. Use them accordingly. Drill Bit Lifespan (Average): 5 to 20 holes each. In soft stone, expect 20 holes per bit. In agate, expect 5 holes
