Ultra-Shear 3-Flute Solid Carbide End Mills for Aluminum
Engineered for Precision. Built for Speed.
When your project calls for aggressive material removal and mirror-smooth finishes in aluminum or other non-ferrous metals, Ultra-Shear 3-Flute End Mills deliver on all fronts. These American-made, solid carbide tools are optimized for aluminum machining—offering high performance, long tool life, and factory-direct value.
Optimized for Non-Ferrous Excellence
🔹 3-Flute Geometry
The 3-flute design strikes the perfect balance between chip evacuation and surface finish, maximizing feed rates and reducing cycle times.
🔹 Center-Cutting Design
Perfect for plunging, ramping, and pocketing, giving you flexibility across a wide range of aluminum machining strategies.
🔹 37.5° Helix Angle
Higher helix reduces spindle loads, enhances chip evacuation, and minimizes heat buildup for a cooler, cleaner cut—especially in soft, gummy materials like aluminum and brass.
🔹 Exceptional Wall & Floor Finish
Meticulous grinding and precision edge prep result in finishes that often require no secondary sanding or polishing.
🔹 Uncoated for Maximum Versatility
These bits are ideal for use with aluminum and other non-ferrous metals where coatings are not needed. Pair with proper coolant or lubrication for best results.
🔹 Precision Tolerances
- Shank Tolerance: H6
- Diameter Tolerance: +.0000" / –.0005"
Consistent sizing ensures smooth performance in toolholders and collets.
