Precision Milling Cutters,Cutting Tools for CNC Machining Every Material
A side milling cutter is a cutting tool for groove milling, side cutting, slot machining, shoulder milling, and side surface machining. Manufacturers use it on milling machines and CNC machining centers when a workpiece needs stable side cutting or accurate groove width.
Compared with a standard end mill, a side milling cutter is often better for wider grooves, side faces, shoulders, and special slotting operations. Therefore, it is suitable for fixture parts, mold components, machinery parts, automotive parts, and custom CNC metal parts.
Cutterbest supplies carbide side milling cutters in different diameters, cutting widths, flute counts, coatings, and custom designs. In addition, we can support custom side milling cutter production based on your drawing, material, machine, and cutting requirements.
What Is a Side Milling Cutter?
A side milling cutter is a rotary milling tool that cuts with its side teeth and outer cutting edges. It is mainly used to machine grooves, slots, shoulders, and side surfaces.
Many manufacturers choose side milling cutters when a standard end mill is not the best choice for the groove width, side cutting area, or machining stability. As a result, this tool is useful for fixture plates, machine parts, mold components, and other precision metal parts.

How to Choose a Side Milling Cutter
Before choosing a side milling cutter, check the groove size, workpiece material, cutting depth, cutter diameter, cutting width, machine rigidity, and surface requirement.
| Selection Point | What to Check |
| Groove Width | Match the cutting width to the required slot or groove |
| Cutter Diameter | Choose based on groove depth and machine condition |
| Workpiece Material | Aluminum, steel, stainless steel, cast iron, mold steel |
| Flute Count | Select by material, chip space, and cutting stability |
| Coating | Choose coating based on heat, wear, and material type |
| Cutting Depth | Avoid overloading the cutter during deep cutting |
| Machine Rigidity | Side cutting needs stable machine and tool holding |
| Surface Requirement | Roughing, semi-finishing, or finishing |
If you are not sure which side milling tool to choose, send us your drawing, material, groove width, cutter size, machine type, and machining requirement. We can recommend a suitable side milling cutter design.
Side Milling Cutter vs End Mill Cutter
Side milling cutters and end mill cutters are used for different machining needs. An end mill cutter is more common for slotting, pocket milling, and profiling. A side milling cutter is more suitable for grooves, shoulders, side faces, and wider slot machining.
| Item | Side Milling Cutter | End Mill Cutter |
|---|---|---|
| Main Use | Grooves, side cutting, shoulders | Slotting, profiling, pocket milling |
| Cutting Area | Side face and circumference | End and side cutting |
| Best For | Wider grooves and side surfaces | General CNC milling |
| Custom Need | Often customized by width and diameter | Often selected by diameter and flute length |
| Typical Parts | Fixtures, mold components, machinery parts | Pockets, slots, contours, profiles |
For general slotting and profiling, view our end mill cutter.
