Applied Diamond Tools has introduced its newest product: Diamond Drum Core Bits.  With sintered diamond segments on the rim and vacuum brazed diamond surrounding the body of core bits, they can be used as both a diamond core drill bit and as a diamond drum wheel. Instead of buying a diamond core bit and a diamond drum wheel, now only one tool is needed. This tool will offer great savings as well as convenience, reports Applied Diamond Tools. In addition, they are great for fine tuning core holes for modern faucet diameters.
