This product adopts an industrial-grade standard design, with core parameters precisely matched to professional construction needs: the material uses a high-strength 45# steel base and YG6 carbide, balancing the toughness of the base and the sharpness of the cutting edge; the surface is sandblasted to effectively improve wear resistance and anti-slip performance, extending service life; the size covers common specifications of 35-65mm, with a total length of 500mm to meet the needs of deep drilling; equipped with a standard SDS MAX tool holder, it can be seamlessly adapted to various SDS MAX specification electric hammers, making installation convenient and highly versatile.

Product Advantages
1. Superior material combination for sharper and more durable cutting: Made of high-grade 45# steel and YG6 carbide, the carbide cutting tip has high hardness and strong wear resistance, making it easy to cut hard materials such as concrete and brick walls. Combined with the excellent toughness of the 45# steel base, it effectively avoids the cutting tip breakage and greatly extends the tool’s service life.

2. Circular alloy blade assembly for uniform force distribution and reduced chipping: The innovative circular alloy blade assembly design ensures that each blade evenly distributes the workload during drilling, preventing chipping caused by excessive local force, ensuring a stable and smooth cutting process, and guaranteeing a smooth and flat drilled edge, reducing subsequent finishing processes.

3. High-frequency welding process for a stronger and more reliable connection: Utilizing advanced high-frequency welding technology, the weld between the cutter head and the base material achieves extremely high bonding strength. The inner and outer welds are smooth and flat, resulting in not only a refined appearance but also ensuring that the welded parts are less likely to detach during high-frequency impact drilling operations, improving operational safety and tool durability. Compared to traditional welding, this process also effectively reduces the heat-affected zone, preventing material performance degradation and further guaranteeing product quality.

Applicable Scenarios
This product is specifically designed for drilling into hard materials, suitable for various working conditions such as brick walls and concrete walls. It is especially suitable for air conditioner installation drilling, and can also meet the drilling needs of water and electricity renovation, pipeline laying, and other scenarios. Whether for professional construction teams or individual DIY projects, its high-efficiency cutting and stable performance can significantly improve drilling efficiency and construction quality. SDS MAX Breakthrough Bit, Thru Hole Bit Carbide Tipped
