Anchor drill bits come in a variety of sizes and shapes, each designed to tackle different soil conditions and drilling requirements. The most common types include twist drills, core drills, and hole saws. Twist drills are the most versatile and are suitable for a wide range of materials, including wood, metal, and masonry. Core drills, on the other hand, are designed to cut cylindrical holes in hard materials like concrete and stone. Hole saws are best suited for creating large diameter holes quickly and efficiently.

The choice of drill rod steel is crucial due to the harsh conditions it encounters. It needs to be strong enough to resist bending and breaking under immense pressure, while also being resilient against wear and tear caused by friction and abrasive materials. Typically, drill rod steel is composed of high-carbon alloy steels, often containing elements like manganese, chromium, and nickel to enhance strength, toughness, and resistance to corrosion.

Another important feature of tapered rock button drill bits is the placement of rock buttons on the bit. These rock buttons are typically made of hard tungsten carbide material, which is known for its excellent wear resistance and durability. The rock buttons are strategically placed on the drill bit to provide maximum impact and cutting power, allowing for efficient rock penetration and faster drilling speeds
