## Abstract

A head of a cutting device includes a base configured to be fixed to a machine tool, a cylindrical suction nozzle integral with the base, a connector integral with the base and configured to receive a suction pipe. The suction nozzle is perforated by at least one oblong hole, for example parallel to an axis of the suction nozzle.

## Claims

### Claim 1

A cutting device comprising
a head, said head comprising:
a base configured to be fixed to a machine tool;
a cylindrical suction nozzle integral with the base;
a connector integral with the head and configured to receive a suction pipe;
said suction nozzle being perforated by at least one oblong hole parallel to an axis of said suction nozzle,
a mount to which said head is fixed;
a drive system in which a cutting tool is fixed, said drive system being configured to drive said cutting tool in rotation about an axis and in translation parallel to said axis; and
at least one infrared sensor fixed in a hole that is formed in a wall of said head and opens onto a cutting zone inside said head, said infrared sensor being connected to a detection module for detecting an outbreak of fire.

### Claim 2 (depends on 1)

The cutting device according to claim 1, wherein the suction nozzle is perforated by circular holes along an edge of an end configured to press against a part to be cut.

### Claim 3 (depends on 1)

The cutting device according to claim 1, wherein said at least one oblong hole is formed of two circular arcs connected by longitudinal straight lines, each arc having a radius of 6 mm and a distance between centers of the circular arcs being 10 mm.

### Claim 4 (depends on 1)

The cutting device according to claim 1, wherein said suction nozzle and said cutting tool are coaxial.

### Claim 5 (depends on 1)

A system comprising
a cutting device according to claim 1, and
a control module configured to safeguard said cutting device if an outbreak of fire is detected by said detection module,
said module for detecting the outbreak of fire and said control module being connected by wireless communication.
