Widin Carbide End Mill For Stainless & Exotics - 4 Flute Double Core - Variable Helix - Square Edge - 20mm

The Widin Carbide End Mill is a 20 mm diameter cutting tool designed for stainless steel and exotic alloys. With a 4-flute, double-core construction and a variable helix, it delivers efficient material removal, solid rigidity, and a smooth surface finish on challenging metals.

Designed for engineers, fabricators, tradespeople, and serious hobbyists, this end mill combines unequal index flutes, a double-core design, and a square-edge profile to support consistent, high-quality results. The tool’s geometry helps maintain accuracy under demanding cuts while promoting reliable chip evacuation.

• Unequal index flutes for chip control: Excellent chip emission and smooth workpiece surface finish by applying unequal index flutes.
• Double-core construction for anti-bending strength: Anti-bending strength with double core type, improving stability and tool life during tough cuts.
• 20 mm diameter, 4-flute, variable helix with square edge: Versatile, precise cutting geometry at 20 mm that delivers clean edges and reliable performance on stainless and exotic materials.

This end mill helps you complete projects more efficiently by delivering reliable cutting in a single setup, reducing rework and downtime. The combination of chip-control, rigidity, and a refined cutting geometry translates to more consistent tolerances, cleaner surfaces, and longer tool life—making it a dependable choice for production runs or demanding, precision-focused work.
