A manual ceramic cutter with an adjustable set-square, having a set-square (1) installed at one of the longitudinal extremities of a base (2) for supporting the ceramic items to be cut, and a manually-operated cutting head (3) installed with the possibility of displacement along a number of longitudinal guides (4). This cutter comprises adjustment means (13, 14) of the perpendicularity of the set-square (1) with regard to a cutting line (L1) of the cutter, and fixing means (11, 12) of the set-square (1) to the base (2). It further comprises visual verification means of the perpendicularity of the set-square (1) with regard to the cutting line (L1).

A portable cutting machine is provided. The portable cutting machine comprises: a cutting portion including a disc-shaped cutting blade that cuts an object to be cut by rotating, and a first rotation axis that serves as a rotation center of the cutting blade; a drive portion including a drive source and a second rotation axis rotating by drive of the drive source; a transmission portion including a first pulley fixed to the first rotation axis, a second pulley fixed to the second rotation axis, and a belt looped around the first pulley and the second pulley, and configured to transmit a rotational force by the drive portion to the cutting portion; and a case including a storage space for storing the transmission portion and at least one communication portion that connect to the storage space and open to outside.

The invention relates to a rotary blade assembly that can be used in tile-cutting machines, which has an annular blade (1) mounted on a bearing (2) comprising an inner race (21), and outer race (22) and ball bearings (23). A first side of the outer race (22) comprises a perimeter projection (24) that forms a stop for mounting the blade (1) on the bearing. A securing ring (3) that forms a second stop for mounting the blade (1) is mounted and secured on the second side of the outer race (22), the bearing and/or the securing ring comprising projections or recesses (31, 25, 26) which are coupled to complementary recesses or projections (11, 12) defined in the blade and which prevent the relative rotation of the blade (1) with respect to the securing ring (3) and the outer race (22) of the bearing (2).
