75.00 on the low end for a small bit is a more realistic price for a quality bit that will last through many jobs. Good core bits will drill through concrete, stone, etc., and last many years. A good core bit set of 1", 1 1/4", 1 1/2", 2", 3", and 4" is a hefty investment well over a thousand dollars. Add the 1/2" increments and the 5" and 6" bits, and you are into several thousand dollars.

What are Diamond Core Drill Bits and Why Should You Use Them?

Known as the most effective and efficient method of cutting tough materials, diamond core drill bits are widely used in the tiling industry to drill holes in tiles. But what are diamond core drill bits and what are their advantages compared to other drill bits? Here are a few facts about diamond core bits.

What are Diamond Core Drill Bits:

Diamond core bits are drill bits that are welded with tiny particles of diamond, the toughest material known. As such, these drill bits can cut through the hardest of tiles, including porcelain, ceramics, marble, granite, and vitrified tiles.

The most common methods of manufacturing diamond drill bits are electroplating and vacuum brazing. Vacuum-brazed diamond bits are made by welding diamond particles in a vacuum brazing furnace of extremely high temperature. Vacuum-brazed diamond bits are more durable, retain their sharpness for a longer time, and can cut through harder tiles.

All OTEC diamond core bits by Amark Group are made using the vacuum brazing method to provide tilers with the most durable tools for precision drilling of tiles.

What are the Advantages of Diamond Core Drill Bits:

1. They can cut through the toughest of tiles: Diamond is the toughest material out there. Compared to drill bits made from other materials, diamond drill bits can cut through tougher tiles such as vitrified porcelain, granite, and even concrete.
2. Less debris and dust: Due to their immense cutting strength, diamond drill bits can cut through tough materials with ease, thus producing less debris and dust during operation.
3. Diamond drill bits can be used with incredible speed: Tearing through everything from concrete to marble, Amark's OTEC Diamond Core Drill Bits can be used at up to 11,000 rpm.
4. Diamond Core Drill Bits make less noise: The speed and ease by which they can cut through strong materials mean that diamond drill bits create much less noise during operation compared to other drill bits. Reducing noise on a construction site is a significant positive.
5. Cost effective: Diamonds are used in the making of diamond core bits, which might seem more expensive compared to core bits made from other materials. However, the durability of diamond core bits makes them more cost-effective in the long run.
6. Good for the environment and your health: Minimal noise, debris, and dust make diamond core drill bits among the most environmentally friendly and health-conscious options available.
