Sedgwick 571 Mortiser

Description

The Sedgwick 571 is a traditional hollow chisel mortiser designed for cutting square mortices in timber with speed and accuracy. Widely regarded as a proven and dependable machine, it is built for long-term use in professional workshops, joinery environments and training settings where consistent results are essential.

At its core is a heavy cast iron frame, including the base, column, table and slideways, which provides excellent rigidity and minimises vibration during operation. This solid construction allows the machine to produce clean, accurate mortices even when working with harder materials or larger sections of timber.

The chisel head is counterbalanced by a weight rather than a spring system, giving smooth, controlled movement and reducing wear over time. This design allows the operator to raise and lower the head with minimal effort while maintaining precision throughout the cut.

The machine uses a hollow chisel and auger system, where the drill bit removes the bulk of the material and the square chisel shapes the mortice. A fully enclosed adjustable chuck holds the auger securely in line with the chisel, improving cutting performance and extending tool life.

For ease of use, the table moves both longitudinally and laterally via a single handwheel, allowing precise positioning of the workpiece. Adjustable stops, a marking-out rail and a two-position depth stop make it easier to carry out repeat work, reducing setup time and improving consistency across batches.

With its straightforward setup, durable construction and proven design, the Sedgwick 571 remains a reliable choice for workshops that need accurate mortising without the complexity of more advanced automated systems.
