LEUCO t3-System Cutters with Triangular Replaceable Knife Inserts

LEUCO t3-System Cutters with Triangular Replaceable Knife Inserts

The new LEUCO t3-System cutter can be used on CNC machines and traditional machines for chip-free spiral plunge-cutting, rabbeting and chamfering. Its narrow profile lets a shop complete joining, rabbeting and sizing of solid wood and wood-based materials, even when space is limited. With its special arrangement of triangular cutting edges, it can produce absolutely chip-free surfaces, which in door and furniture manufacturing means less rework. This is particularly beneficial when producing door rabbets. And spiral plunge-cutting with this tool lets a shop produce small cutouts so that tenons and specialty joints can be created. With its compact, slim design, the tool is ideal for cutting of free forms such as round curves, or string wreaths in stair construction.

In long-time tests, the t3-System clearly exceeded quality goals, in both demanding craftsmanship and industrial applications with high output. In addition to the sizes shown in the online catalog, other dimensions are available on request.

LEUCO has a patent pending for the t3’s cutting-edge arrangement. The triangular replaceable knives with rounded edges allow the shear angle for the draw cut be set perfectly, thereby preventing any offsets where two cuts meet. The shear angle can be set so that outstanding surface and edge processing can be achieved when joining and rabbeting and the rear of the cutter does not protrude. This distinguishes the t3-System from other spiral cutterheads because with square turnover knives, the outermost cutting edge always pulls towards the edge, which results in poorly cut edges. The t3 triangular knife inserts are positioned so that the shear angle always pulls in the correct direction, and the optimized axis angle of the cutting edge results in low cutting pressure. This not only enables high cutting performance, but also leads to low wear of the carbide turnover knife insert. There’s a YouTube™ video (in German with English subtitles) here.
