Diamond Wire Hollow Drill

Diamond Wire Hollow Drill

Diamond Wire Hollow Core Drill Bitsfeature a diamond-coated tip on a durable metal base, designed to make precise holes in hard-to-cut materials. Unlike conventional twist drills, these bits grind the material gently, allowing for controlled, clean cuts. Core drills remove only a small circle of material, making them faster than solid drills, while larger sizes can produce a usable core. Suitable for stone, glass, tile, composites, plastics, resins, porcelain, eggs, and more, smaller bits work with hand drills or rotary tools like Dremel or Foredom, whereas larger bits are best used with a drill press. Patience is key for optimal results, as the diamond grinding process ensures precision without damaging delicate materials.
