Maximize chip evacuation and surface finish with our Solid Carbide End Mills for Aluminum.
Featuring polished flutes and high-helix geometry to eliminate built-up edge (BUE) in non-ferrous machining.
Unlock Maximum Speed: The Ultimate End Mills for Aluminum Applications
Machining aluminum and non-ferrous materials presents a unique set of challenges—primarily chip welding and built-up edge (BUE). Our High-Performance Aluminum Series is engineered to overcome these obstacles, transforming how you machine soft, gummy materials.
Designed with specialized geometry and an ultra-high polish, these solid carbide end mills ensure rapid chip evacuation, allowing you to run at higher feeds and speeds while achieving a mirror-like finish.

Frequently Asked Questions (FAQ)
Q: Why should I use a 3-flute end mill instead of a 4-flute for aluminum?
A: A 4-flute end mill leaves very little room for chips to escape. Because aluminum chips are large and gummy, they can clog a 4-flute tool instantly, leading to tool breakage. A 3-flute design strikes the perfect balance: it has large gullets for chip evacuation but a stronger core than a 2-flute tool, allowing for higher feed rates.
Q: Can I use AlTiN coated tools for aluminum?
A: No. You should avoid AlTiN (Aluminum Titanium Nitride) coatings. Because the coating contains aluminum, it has a chemical affinity to the workpiece material. This causes the aluminum to “stick” to the tool (galling), ruining the tool and the part. Stick to Uncoated, ZrN, or DLC.
Q: Do I need coolant when using these tools?
A: Yes. While our polished flutes mitigate heat, aluminum machining benefits greatly from flood coolant or an air-oil mist (MQL). This helps flush chips away from the cutting zone and keeps the cutting edge temperature down to prevent sticking.
Q: What is the benefit of the Corner Radius option?
A: A sharp corner is the weakest point of an end mill. Adding a small corner radius (e.g., 0.5mm or 0.020″) significantly strengthens the tool tip, preventing chipping and increasing tool life, especially during aggressive roughing.
