Choosing Between the AlumaMill & AlumaMill
The 3825 AlumaMill is designed for aggressive material removal in high-silicon aluminum, composites, plastics, and wood. Its 2-flute, 45° helix geometry is available in ball, corner-radius, and square end styles for added application flexibility. When floor finish is the priority, consider the 3835 AlumaMill. Its 3-flute, 36° helix design features a wiper flat for improved floor finishes and is available with a square end.
