Diamond is the hardest natural mineral. Seventy-five percent of diamonds mined are used by industry to maximize the cutting ability of tools and bits.
The best Dremel bits for cutting and shaping glass are diamond-coated bits, such as diamond wheel points or diamond drill bits. These bits are specifically designed to cut through glass effectively and create precise shapes.
Those types of blades and bits are mainly for cutting tiles and stone.
A hollow diamond drill bit, with lots of water, cutting slowly, will do the job. Ideally in a drill press of some kind instead of freehand. Diamond bits in rotary tools like Foredom or Dremel may do it, if it's suitable to use them with lots of water.
The basic categories of cutting tools are linear and rotary machines. Linear cutting tools include tool bits and broaches. Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, milling cutters, reamers, and cold saw blades.
The different types of drill bits available for cutting large holes in wood include spade bits, auger bits, Forstner bits, and hole saw drill bits. Each type is designed for specific cutting tasks and hole sizes in wood.
The only tool that uses drill bits is a drill. There are, however, many different types of drill bits. The drill bits vary by material, size, shape, and function.
Diamond jewelery makes up about 25% of the use for diamonds, the remainder is used for industrial manufacture, including drill bits, and other tools.
Diamond tipped drill bits
Diamond Core Drill Bits are the best for concrete.
Most diamonds mined across the world -- 75% -- end up being used in industry, on the blades of cutting tools like saw blades and drill bits. I think it's wrong to automatically assume diamonds = jewelry.
