Abstract: A device is provided to assist in the cutting, mitrering, chamfering, and similar operations of ceramic and other tiles. The device can be readily attached to, and subsequently removed from, a cutting implement, such as an angle grinder or a circular saw or jig saw. The device includes an elongate L-shaped member (1). Approximately mid-length of the member (1), there is a slot (2). A first shaped, rigid arm (3) is fixed at one of its ends (4) to one end (5) of the elongate member (1) by rivets (6). Near the other end (7) of the arm (3), there is a hole (8). A second shaped, rigid arm (9) is fixed at one of its ends (10) to the other end (11) of the elongate member (1) by rivets (12). Near the other end (13) of the arm (9) there is a hole (14).
