Drill Bit

Common Specifications

Material: Most drip drill bits are made from durable metal (often stainless steel or mild steel) to ensure longevity and prevent damage to the pipes during drilling.
Diameter: The bit diameter corresponds to the size of the grommet or take-off fitting it is designed to accommodate. Common sizes include 12mm, 16mm, 19mm, 20mm, 22mm, and 32mm.
Power Source: They are primarily manual tools, often featuring an ergonomic T-shape handle for simple and safe operation.
Application: These bits are specifically for making holes in mainline pipes (PVC, HDPE, LDPE) to install connectors, grommets, and barbed take-offs.
Design: Many feature a specific design, like an adjustable center tip or stepped profile, to ensure a smooth, perfect, and leak-proof hole without cracking the pipe.
Compatibility: The hole size determines the compatibility with other drip irrigation components, such as 16mm or 32mm off-takes for extending lines.
