Alpha Drill Bits & Grinder Adapter. Premium Bit for Drilling Anchor Holes. Alpha introduces the Electroplated Wet Diamond Drill Bits for drilling holes in tile and stone for pre-installation or post-installation placement. Alpha Drill Bits & Grinder Adapter work great on Marble, Granite, Engineered Stone, Ceramic, Porcelain, and Glass Tile & panels. They can be used on a standard 3/8” or larger drill but also fit on water-fed polishers with 5/8”-11 spindles using the Drill bit Adapter. Available in 3/16”, 1/4”, 5/16”, 3/8”, 1/2”, 1-3/8” & 1-1/2” sizes, are ideal for drilling holes for Anchors for bathroom fixtures, faucet, and plumbing pipes. Electroplated drill bits are a must-have for the tile installer’s toolbox.

Core drill bits have a hollow center and cut a circle in the material to create a hole. This results in a hole the size of the bit and a smaller “plug” or “core” that comes from the center.

Among the main features of Alpha Drill Bits & Grinder Adapter, we find:

  • Premium electroplated bits for drilling fastening holes, comer holes for cut-outs, pipe & faucet holes. Cut clean, smooth holes.

Diamond drill bits are easy to use, however, there are many special techniques that are different from standard steel-bit drilling.  Diamond drill bit usage can also vary depending upon the type and the specific manufacturer.

SPEED KILLS: Reduced drill speeds, low drill pressure, and increased use of water lubrication will extend drill bit life considerably.
Because diamond drill bits are used to drill in extremely hard materials, it is very important to use proper drill pressure to keep from overheating the bit.  Excessive pressure is merely converted to heat energy and can burn up a bit very quickly
