The drill chuck with key ensures perfect drilling concentricity and optimal force transmission when working with both impact and non-impact drills. It guarantees a secure, stable grip on drill bits, even under heavy loads. The use of the key increases the clamping force, reducing the risk of tool slippage during work.
