Sintered granite diamond core drilling bit?HUAZUAN Sintered Diamond Diamond Drill BitDiamond Sintered Diamond Drill Bits are also know as Sintered Diamond Core Drill Bits or Sintered Diamond Hole Saws.? These are professional quality, heavy-duty diamond drill bits designed for use on ceramic tile, porcelain tile, limestone, sandstone, marble, granite, quartz and other stone, plus bricks, masonry, concrete block, and concrete.? Water must be used for lubrication.Sintered diamond drill bits are not very effective for glass type materials or softer stone materials such as slate and are?not recommended for use on glass or slate.? Electroplated diamond bits are much more effective for those types of materials.?Sintered diamond drill bits have the diamonds embedded into the metal of the drill bit tip rather than merely & quot;boned& quot; to the tip as with electroplated?diamond drill bits. ?As the tip wears down on a sintered diamond drill bit, new diamonds come to the surface. ?The tip sidewall of HUAZUAN Sintered Diamond Drill Bits is 2mm thick on the smaller size bits (1& quot; and below) and increases to 2.5mm to 3mm thick on larger size bits.?Sintered diamond drill bits are heavy-duty bits designed for long life. ?Generally, sintered bits will have a long life of 20 to 30 or more times the life of a electroplated?diamond drill bit, if used properly. ?The heavy-duty design provides long life when drilling in very hard materials such as porcelain tile, granite and hard stones.Diamond drill bits are easy to use, but there are many drilling techniques that are different from standard steel-bit drilling. ?Diamond drill bit usage can also vary depending upon the diamond drill bit type and the specific manufacturer.Diamond Drill BitsRecommended Drill SpeedsDesigned for long-term use in materials up to 1-3/4& quot; thick(Not for use with Hammer Drills)Sintered Diamond Drill Bitwith optional center pilot bit.Because diamond drill bits are used to drill in extremely hard materials, it is very import
