Milling cutter types vary by shape, cutting edge design, flute count, rivestimento, and machining purpose. Each cutter type is designed for a different CNC milling operation, such as slotting, facing, profilazione, 3D contouring, sgrossatura, finitura, or thread machining.
Choosing the right milling cutter type is important for tool life, finitura superficiale, chip removal, e stabilità della lavorazione. Per esempio, an end mill cutter is commonly used for slotting and profiling, while a ball nose end mill is better for curved surfaces and mold cavities.
Perciò, this guide explains common types of milling cutters, their uses, and how to choose the right cutter type for different CNC machining applications.
What Are Milling Cutter Types?
Milling cutter types refer to different cutter designs used for different machining tasks. Some cutters remove material quickly. Some create flat surfaces. Others machine slots, threads, superfici curve, or special profiles.
Nella lavorazione CNC, the cutter type should match the operation, materiale del pezzo, rigidità della macchina, and surface requirement. A wrong cutter type may cause poor surface finish, vibrazione, chip clogging, o una breve durata dell'utensile.

Main Types of Milling Cutters
Fresa a candela
An end mill cutter is one of the most common milling cutter types. It can cut from the side and the end of the tool, so it is suitable for slotting, profilazione, fresatura di tasche, contornatura, e fresatura di spallamenti.
End mills come in different flute counts, rivestimenti, lengths, and carbide grades. Per esempio, 2 flute end mills are often used for aluminum because they provide more chip space. In contrast, 4 flute end mills are often used for steel because they offer better rigidity and cutting stability.

Fresa a candela a testa sferica
A ball nose end mill has a round cutting tip. This cutter type is used for 3D contouring, superfici curve, cavità dello stampo, die machining, and precision finishing.
Compared with a flat end mill, a ball nose cutter can follow curved tool paths more smoothly. Tuttavia, it is not the best choice for sharp inside corners because the cutting tip is round.
For mold machining and curved surfaces, scegliere Frese a candela a testa sferica.
Fresa a punta di toro
A bull nose end mill is also called a corner radius end mill. It has a small radius on the cutting corner. This design improves corner strength and reduces chipping during machining.
Bull nose end mills are useful for semi-finishing, rough finishing, and machining materials such as steel and stainless steel. They are a good choice when a sharp square corner is not required, but stronger tool corners are needed.
For semi-finishing and stronger corners, Vedere fresa a candela a testa tonda.
Fresa per scanalature a T
A T-slot cutter machines T-shaped slots and undercuts. These slots are common in machine tables, infissi, molds, and clamping systems.
Generalmente, an end mill first opens a straight slot. Poi, the T-slot cutter creates the wider undercut shape. This process helps reduce tool load and improves machining stability.
For T-slot and undercut machining, use a T-slot cutter.
Fresa laterale
A side milling cutter cuts grooves, slot, and side surfaces. It removes material from the side of the workpiece and works well for wider grooves or vertical side cutting.
This cutter type is often used in general machinery, fixture parts, mold components, and metalworking applications. Tuttavia, the setup must be stable because side cutting can create higher cutting forces.
For groove and side surface machining, Vedere fresa laterale.
Fresa per spianatura
A face milling cutter is used to machine flat surfaces. It is often used for large surfaces, machine bases, mold plates, piastre di fissaggio, and metal blocks.
Compared with a small end mill, a face milling cutter can cover a wider cutting area. Perciò, it is suitable when the workpiece needs a clean, flat, and consistent surface before the next machining step.
Face milling cutters are useful when the workpiece needs a clean, flat, and consistent surface before the next machining step.
Fresa per filettare
A thread milling cutter machines internal or external threads on CNC machines. It can be useful when the part needs accurate threads, different thread sizes, or better control than traditional tapping.
Thread milling also helps reduce the risk of tap breakage in some difficult materials. Tuttavia, it requires proper CNC programming and a stable machining setup.
Thread milling is useful for precision thread machining, but it requires proper CNC programming and a stable machining setup.
Fresa per sgrossatura
A roughing end mill is designed for fast material removal. It usually has a special cutting edge design that breaks chips into smaller pieces and reduces cutting pressure.
This cutter type is often used before finishing. It removes extra material quickly and prepares the part for a smoother final surface. Tuttavia, roughing end mills are not usually used when the final surface finish is the main requirement.
Roughing end mills are suitable for fast stock removal before finishing, especially when machining efficiency is more important than final surface quality.
Diamond-Coated End Mill
Diamond-coated end mills are used for graphite, CFRP, compositi, and other abrasive materials. These materials can wear normal cutting edges quickly, so coating selection is very important.
Diamond coating can improve wear resistance and help extend tool life in graphite machining. Tuttavia, the tool should still match the workpiece material, cutting parameters, and machine condition.
For graphite and abrasive materials, scegliere frese con rivestimento diamantato.

How to Choose Milling Cutter Types by Operation
Different machining operations need different cutter types. Perciò, you should choose the cutter based on the cutting task first.
| Operazione di lavorazione | Recommended Cutter Type | Reason |
|---|---|---|
| Scanalatura | End mill cutter | Good for straight slots and pockets |
| T-slot machining | T-slot cutter | Creates T-shaped slots and undercuts |
| Facing | Fresa per spianatura | Machines flat surfaces efficiently |
| Profiling | End mill cutter | Cuts side walls and contours |
| 3D contouring | Fresa a punta sferica | Follows curved surfaces |
| Semi-finishing | Fresa a punta toro | Provides stronger cutting corners |
| Sgrossatura | Roughing end mill | Removes material faster |
| Thread machining | Thread milling cutter | Cuts internal and external threads |
| Graphite machining | Diamond-coated end mill | Improves wear resistance |
Cutter Type for Slotting
End mill cutters are usually the most common choice for slotting. In aluminum machining, UN 2 fresa a candela a flauto often works well because it provides more chip space.
When cutting steel slots, machinists may choose a 2 flauto o 4 flute tool depending on slot depth, coolant, e rigidità della macchina.
Cutter Type for Steel Machining
Steel needs stronger cutting edges and better tool rigidity. Per questo motivo, UN 4 fresa a candela a flauto is often used for general steel milling, profilazione, and side milling.
Inoltre, coated carbide tools can improve heat resistance and tool life.
Cutter Type for Finishing
Finishing requires stable cutting and better surface quality. Perciò, many machinists choose 4 flauto o 6 fresa a candela a flauto tools when chip evacuation is not a major problem.
A higher flute count can improve surface finish, but the tool must match the machine rigidity and cutting parameters.
How to Choose Milling Cutter Types by Material
Workpiece material also affects cutter selection. A cutter type that works well for aluminum may not work well for stainless steel or graphite.
| Materiale del pezzo | Suggested Cutter Type | Main Reason |
| Alluminio | 2 flauto o 3 fresa a candela a flauto | Migliore evacuazione del truciolo |
| Acciaio | 4 fresa in metallo duro con scanalatura | Better rigidity and stability |
| Acciaio inossidabile | Coated carbide end mill | Better heat and wear resistance |
| Grafite | Diamond-coated end mill | Migliore resistenza all'usura |
| Acciaio temprato | High-performance coated carbide tool | Stronger cutting edge |
| Plastic | 1 flauto o 2 strumento flauto | Reduces chip clogging |
When choosing a cutter type, do not only compare price. Invece, controllare il materiale del pezzo, profondità di taglio, tool length, rivestimento, flute count, e requisiti di finitura superficiale.
For high-performance carbide tools, Vedere fresa a candela in metallo duro.
