38 Inch 10 mm Heavy Duty Pro Sintered Diamond Drill Bit Cement Marble Granite Quartz Masonry Brick Ceramic Tile Porcelain Tile Limestone Block #ad

3/8″ Inch 10 mm Heavy Duty Pro Sintered Diamond Drill Bit Cement Marble Granite Quartz Masonry Brick Ceramic Tile Porcelain Tile Limestone Block

3/8″ Inch 10 mm Heavy Duty Pro Sintered Diamond Drill Bit Cement Marble Granite Quartz Masonry Brick Ceramic Tile Porcelain Tile Limestone Block #ad - There are some disadvantages. However, for highly repetitive drilling in hard mateirals, the higher cost of the sintered diamond drill bits is well worth it because of the much longer drill bit life. As the tip wears down on a sintered diamond drill bit, new diamonds come to the surface. Sintered diamond drill bits have the diamonds embedded into the metal of the drill bit tip rather than merely “bonded” to the tip as with bonded diamond drill bits. Generally, sintered bits will have a long life of 20 to 30 or more times the life of a bonded diamond drill bit, if used properly. Sintered bits are more expensive than bonded diamond bits and the thick heavy-duty tip causes them to drill more slowly than thin-wall bonded diamond drill bits. Sintered bits are also necessary for drilling beyond about 1/2″ deep as the heavy-duty design can withstand the severe heat of deeper drilling in hard materials. The heavy-duty design provides long life when drilling in very hard materials such as porcelain tile, granite and hard stones. Sintered diamond drill bits are heavy-duty bits designed for long life.

4″ Diamond WET Coring Bit – Concrete Core Drill by BLUEROCK Tools

4″ Diamond WET Coring Bit – Concrete Core Drill by BLUEROCK Tools #ad - The decision to use these bits on materials that they are not primarily designed for will be done at the risk of the user and not covered under our standard business policy. Wet type concrete coring bits are not designed to cut all types of rock. As such, it is extremely difficult for bluerock tools to assess individual projects and speak to how long a bit will last before it needs to be replaced. We consider these core bits to be mid-grade in their performance but sold at a low-grade price point. Our customers tend to consider these bits to be a better value compared to high-grade bits that are a lot more expensive. Bit life varies based on many factors including material type, material density, depth of cut, hole diameter, drilling speed, wet/dry drilling and operator experience. Certain types of rock can be cut, but it will limit the bit life. They are primarily designed to cut concrete. We often hear that even though high-grade bits may last twice as long, they cost four times the price and they are happy buying our bits and getting the same amount of feet cut for half the price. 5″ approximate thread type industry standard 1 1/4″ (directly fits our bluerock z-1 core drills) note to buyers concrete coring bits are considered a consumable part. New, 4″ bluerock tools diamond wet coring bit for core drill. Outside bit diameter 4″ overall length 17″ approximate inside barrel depth 14.
