We design the CNC end milling cutter for CNC machine tools (such as CNC machining centers). It is a high precision end milling cutting tool, and we mainly use it for the efficient machining of complex profiles, grooves, and step surfaces.
What different cnc end mill and cnc milling bits
In CNC machining, people often mention the terms “CNC end mill” and “CNC milling bits”, but their definitions and application scenarios have obvious differences. Here are the key differences:
CNC End Mill
In particular, we use the term to refer to a multi-edge milling cutter, and we mainly use it for operations such as face milling, side wall milling, and slotting.
Screw edge design, cutter head shape variety (such as flat head, ball head, rounded corner, etc.), suitable for complex contour processing.
CNC Milling Bits
May refer to all cutting tools used for milling, including end mill (face mill), slot drill (slot drill), T-slot cutter, etc. The term “bits” is sometimes misused to refer to small bits, but in the milling world it often refers to milling tools
Structural and functional differences
| Sort | CNC End Mill | CNC Milling Bits（广义） |
| Cutting direction | Mainly axial and circumferential cutting (end + side milling) | Depending on the type, it may be axial only (such as a drill) or composite cutting. |
| Number of blades | 2-6 blade, spiral groove design, strong chip removal ability | It may be single-edged (as in some carving knives) or multi-edged (as in face milling cutters). |
| Typical shape | Flat head, ball head, rounded corners, etc | Including end milling cutter, face milling cutter, keyway cutter, T cutter and so on. |
| Application scenario | Complex contours, 3D surfaces, precision slot machining | Cover surface milling, slotting, drilling, chamfering and other processing. |
Practical application suggestion
When choosing CNC End Mill: give priority to processing complexity and material hardness (such as titanium alloy coating cemented carbide)
When selecting Milling Bits: Specify specific requirements (such as face milling cutter, slotted keyway cutter).
so communicating with suppliers or engineers, use specific names (e.g. “face mill”, “ball nose end mill”) rather than general “milling bits”.
