* Inch sizes (1/32, 3/64, 1/16, 5/64, 3/32, 7/64 and 1/8 in) use inch corner radii: .005" (0.13 mm), .010" (0.25 mm) and .015" (0.38 mm).

† Made to order, not stocked. Allow 14–20 business days.

Key Features

Coolant-through shank: delivers coolant to the cutting edge, reducing heat, extending tool life and improving chip evacuation.
Universal Extreme Coating: minimizes built-up edge, providing exceptional tool life and wear resistance in stainless steel and high-temp alloys.
New flute geometry: allows increased feed rates and reduced cycle times.
3-flute design: optimized for superior chip evacuation in difficult materials.
Premium carbide: for rigidity and long tool life.

Applications & Benefits

Applications

Full slotting, dynamic milling, large step-over milling and high-speed finishing.

Ideal Materials

Carbon, alloy and hardened steels (up to 56 HRC), stainless steels, cast iron, titanium, and nickel and cobalt alloys such as Inconel.

Performance Benefits

Long tool life and wear resistance in difficult materials
Reduced built-up edge
Higher feed rates and shorter cycle times

Speeds & Feeds

Recommended starting parameters. Feed per tooth is shown in mm, with inches in parentheses.

For other diameters: Feed / Tooth (mm) = Cut Diameter (mm) × Multiplication Factor
