Condition: new, Year of construction: 2025, Martin T 54 jointer Only with a good surface planer can you create truly perfect foundations. The T54 was developed with precisely this objective in mind. It enables you to easily plane workpieces at the most modern level and to safely provide them with angular edges. The machine is equipped with a TERSA solid steel cutterhead as standard. The Xplane cutterhead, which operates with a drawing cut, is available as an optional extra. Planing bevels is effortless, as any angle between 90° and 45° can be quickly adjusted with the user-friendly one-hand adjustment. The solid cast iron tables of the T54 provide secure support even for large, heavy workpieces. If you need even more support, you can extend both the infeed and outfeed tables by 380 mm each - of course also in cast iron.
