Both models are equipped with a rigid and robust cast-iron construction, ensuring stability and reducing vibration during operation. This design enhances the durability of the machines and extends their lifespan, making them a worthwhile investment for any serious woodshop.

The jointer beds are precision-ground and provide excellent support for long workpieces, while the fence is easily adjustable and provides accurate guidance for various operations, such as jointing and planing. The intuitive controls make it easy for users to switch between different functions and settings, enhancing workflow efficiency.

In terms of mobility, both the 60C and 60HH come with sturdy, adjustable legs and can be fitted with mobility kits that allow for easy movement around the workshop. This flexibility is a significant advantage for woodworkers who need to optimize their workspace.
