• Great Appearance: The green color, as well as the cylindrical shape, makes it look great and more designed.
• Easy to Clean: The surface of this product is smooth and flat, which is easy to clean. You just need to wipe it with a wet rag.
• Concentric Shaft Design: The concentric shaft design makes the drill bit less likely to be off-center during rotation, which reduces the wobble when drilling and allows the product to drill faster.
• Wave Drilling Teeth Design: The wave drilling teeth are very sharp, which can achieve fast drilling and save you a lot of time. The side gap between the wave drilling teeth is relatively large, which makes the product less likely to jam and easier to take cores.
• Multiple Sizes: This product includes four drill bits of different sizes, allowing you to choose the right one according to your preferences and needs, which is very convenient.
• Detachable Design: Two bits with a size of 5.1*37cm/2*14inch and 7.6*37cm/3*14inch are detachable at the end, which makes it easy to dig out the waste.
