Premium Material: Made of high-quality material, durable and convenient to use. Wide Usage: Suitable for automotive manufacturing, mold making, machine making, and other applications. Enhanced Safety: Eliminates the risk of removing the shank from the collet; extends the bit to achieve full cutting depth. Safety Notice: The extension rod must be securely fastened. The clamp nut should be tightened with the same pressure as used for any standard router clamp. Ensure proper cooling during operation. Convenient Design: Allows router bit changes above the table surface, even without a lift. Simplifies bit changes when using a lift, as there is no need to remove the insert ring. Ideal for custom routing tables with thick tops, providing additional depth for various routing tasks. Features: High precision, stable performance, high resistance, hardness, and durable construction. Enhances efficiency in product processing. Warning: Ensure the router clamp extension is properly assembled before use. The extension rod should be tight, and the clamp nut should be tightened with the same pressure as a standard router clamp.
