I recently purchased a multipurpose concrete drill bit and i was pleasantly surprised with its performance .Based on my experience this is a must-have for any industrial and scientific cutting tools kit. The antislip feature provided a secure and firm grip, which resulted in accurate and clean drilling. The sharpness and sturdiness of the bit made the drilling process quick and hassle-free. One downside is the price, as it is slightly more expensive than other drill bits on the market..
