If it's a cutting tool, we can sharpen it or make it!
Solid Dura-Carb Aluma-Mill
Two 45º RH Spiral RH Cut Flutes • Center Cutting
For high-speed machining of aluminum and non-ferrous materials
The Aluma-Mill is available in two different styles.

The 3815 with it's very aggressive flute design can be operated at very high speed and feed rates, but requires a chamfer to protect the corner.

The 3825 with it's unique flute geometry can be used where a square corner is required.
