CUTTING TOOLS
These are tools designed to shape a part by removing material (drilling, turning, milling). They can be mounted on a hand tool (chuck, pin vice) or on a machine (Lathe, Milling machine, Automatic lathe, Drill, etc.).
GRAVERS
Used by many watchmaking craftsmen (engravers, watchmakers, micromechanics specialists, etc.), gravers are cutting tools. Their size, shape and material vary according to the specifics of each use. Similarly, gravers can be handled and held directly by the craftsman’s hand or be attached to a machine (burin fixe, lathe, automatic lathe, machining center, etc.).
DIES
Dies are cutting tools designed to form an external thread — in other words, a screw thread — on the circumference of a cylindrical rod.
DRILL BITS
Cutting tools intended to drill cylindrical holes. The drill bit can be used with hand tools (chuck, hand drill) or machines (Drill, Lathe, Milling machine, etc.). (Synonym: Drill bit)
MILLING CUTTERS
Rotary cutting tools, fitted with teeth or protrusions intended for machining. Depending on their function and the material to be machined, milling cutters can have very varied shapes and profiles (machining a main plate, cutting a gear tooth, etc.). Milling cutters are made from hard materials in order to reduce wear (hardened steels, hard metals, tungsten carbide, diamond, etc.).
TAPS (THREADING TOOLS)
The tap (threading tool) is a rotary cutting tool used to create the internal thread of a hole — an operation known as tapping. Engaged in a pilot hole of appropriate diameter, it progressively cuts, through chip removal, a helix that will then form the housing for a screw.
