Core Bit Engraving
Diamond tools are usually categorized by manufacturing method or categorized by use. When categorizing by manufacturing method, the core bit drill falls under metal-bonded diamond tools. This means that the bonding material used for such tools is metal mixture powder while the functional parts are usually diamond segments. These tools include diamond blades, grinding cup wheels, diamond core drill bits, etc. Bond quality is one of the primary considerations in selecting which tool to use for cutting or grinding a specific material, depending on its aggregate qualities. The strength of the bond determines the rate at which the metallic powders wear down and expose new diamond crystals at the surface. This is what maintains the abrasive cutting surface. Different bond strengths are achieved by the alloy mix of metallic powders chosen and how much heat and pressure are applied to the sintered segment.

Core Bit Drilling
A core bit drill has two primary uses. One use is to enlarge an existing hole, which may be the result of a core from a casting or a punched hole. This type of core bit drill is solid and they have no cutting point or means of starting a hole. They may also be used to double the size of a hole. Another function of a core bit drill is extracting a whole. Because of its hollow center, it can easily bore a hole in any aggregate material. The result is a hole the size of the drill and a smaller "core" coming from the center. The core holds the material in place, allowing the tool to cut a clean hole through the material. However, a perfect circle or a perfect core can only be seamlessly created through top-grade diamond core bits.

Gila Tools offers you premium quality diamond core bits for thin to thick core drilling in concrete, cured concrete, masonry, stones, tiles, and the like. We also provide top grade wood blades, guaranteed to avoid chipped edges and splintering when making a cut. One of the most important things to look for in a wood blade is its teeth, as it will determine the cleanliness of the cut and its lifespan. Our wood blade is equipped with a carbide tip, which holds a sharp edge for a long period of time. A carbide tip wood blade is known for its durability and can withstand a number of re-sharpening.
