Fullerton Tool’s VMAC End Mill – Versatility and Muscle in Every Cut

by Bernard Martin

If you’re a machinist looking for a solid performer in your end mill arsenal, the VMAC from Fullerton Tool should be on your radar. Whether you're slotting, profiling, or finishing, this 4-flute powerhouse delivers performance, precision, and consistency—especially in tougher materials where tool life really matters.

The VMAC, which stands for Versatile Multi-Application Cutter, is engineered to handle a wide range of ferrous and non-ferrous materials, with a strong emphasis on stainless steels and high-temp alloys. So if you’re burning through tools trying to hold tight tolerances in 17-4, Inconel, or Titanium, this cutter might just be your shop’s new MVP.

Engineered for Versatility
What makes Fullerton Tool's VMAC stand out is its geometry—it’s optimized with a variable helix and a differential flute spacing to minimize chatter, especially on long reaches and deep pockets. You get stable cutting even under aggressive parameters, with less harmonic vibration and a smoother finish.

It’s a go-to cutter for:

• Aerospace components
• Medical-grade stainless parts
• Tool & die work
• General-purpose machining where finish matters

Technical Specs That Matter
Here’s where the VMAC shines on paper—and in your spindle:

• Flute Count: 4 (Standard)
• Helix Angle: Variable, typically 35°–38°
• Shank Tolerance: h6
• Cutting Diameter Tolerance: +0.000” / -0.002”
• Length Options: Stub, Standard, and Long Reach
• Corner Configurations: Sharp, Corner Radius (0.010"–0.060"), or Chamfer
• Coatings:
  • FC20 (AlTiN nano-composite) – Ideal for high-temp alloys and dry machining
  • FC15 (TiAlN) – General-purpose, excellent wear resistance
  • Uncoated – Available for softer materials like aluminum

Size Range
The VMAC comes in a broad range of dimensions to meet your job’s requirements:

• Cutting Diameters: 1/8” to 1” (Metric options also available: 3mm–25mm)
• Overall Lengths: Up to 4.0”
• Flute Lengths: Varies by diameter, from 0.375” up to 2.0”

If you need custom dimensions, Fullerton Tool also supports application-specific modifications through their engineered solutions group—great if you’re running a repeat job with a unique setup.

Built for Productivity
The VMAC isn’t just versatile—it’s a workhorse. Shops report excellent chip control, lower spindle load, and noticeable improvements in surface finish compared to standard 4-flute tools. It’s the kind of cutter that performs well even when you push it harder than you think you should.

Paired with proper toolholders—like a hydraulic chuck or a shrink-fit system—you’ll see the full benefit of this tool’s concentricity and rigidity. Add in high-pressure coolant and optimal speeds & feeds, and the VMAC doesn’t just hold tolerances—it crushes them.

Ready to see what Fullerton Tool's VMAC can do in your own shop? Factory Tooling Solutions makes it easy to run a test tool and dial in the best setup for your application. Whether you're chasing tighter tolerances, longer tool life, or faster cycle times, we’ll help you optimize your machining with the right cutter and support.
