End Mills Quickly Machine Aluminum

A line of high-performance end mills for aluminum materials consists of two- and three-flute tools for roughing and finishing applications. This line, manufactured by Onsrud Cutter, also includes a selection of corner radii and neck and flute lengths. The large “sweet spot” of the tools allows for virtually chatter-free machining at high rpm and on heavy cuts.

A line of high-performance end mills for aluminum materials consists of two- and three-flute tools for roughing and finishing applications. This line, manufactured by Onsrud Cutter, also includes a selection of corner radii and neck and flute lengths. The large “sweet spot” of the tools allows for virtually chatter-free machining at high rpm and on heavy cuts. The resulting maximum metal removal rates contribute to maximum productivity in aluminum-machining applications, the company says.

For machining centers with coolant-through-the-spindle capabilities, the company recommends the same two- and three-flute tools with a coolant-through design that directs the coolant at the cutting edge. The coolant provides lubricant, dissipates heat and clears chips, which is especially important during deep cavity work, resulting in increased tool life and productivity levels.

Coolant at the cutting edge is also said to contribute to quality finishes and to prevent chips from adhering between the flutes. The design also maximizes the effect of minimum-quantity lubricant (MQL) by ensuring that lubricant reaches the cutting edge of the tool.
