Champion 166-5/32X3/16 4-Flute Solid Carbide Center-Cutting End Mill
166-5/32X3/16 is a Champion 4-flute solid carbide center-cutting end mill in 5/32 in x 3/16 in. This standalone product is listed by exact MPN and size so you can select the correct end mill for your milling setup.
Key Benefits
- Solid carbide construction provides high hardness and wear resistance for demanding milling work.
- Four-flute center-cutting geometry supports rigid profiling, slotting and pocketing.
- Rigid construction helps minimize deflection for improved dimensional control.
- Right-hand helix moves chips away from the cutting zone when used with correct feeds and speeds.
- Suitable for general-purpose milling of difficult abrasive and non-ferrous materials.
Applications
- General-purpose milling
- Profiling
- Slotting
- Pocketing
- Difficult abrasive materials
- Non-ferrous materials

How to Use
Secure the end mill in a clean, rigid holder and verify runout before cutting. Select speeds, feeds, stepovers and coolant for the workpiece and tool diameter. Use a controlled plunge only when the setup and cutting conditions support it.
Solid-carbide tools are hard but brittle and may fracture if subjected to impact, excessive runout or incorrect feeds. Use machine guarding, eye protection and proper cutting parameters. California Proposition 65 warning may apply.
