ITC Carbide End Mill Square Edge 3091 - 3 Flute 38° Helix With Trace of Land - Non-Ferrous - 4mm

The ITC Carbide End Mill Square Edge 3091 is a precision milling tool designed for non-ferrous metals. With a 3-flute geometry and a 38° helix, it delivers efficient chip evacuation and stable cutting for clean, accurate parts. The 4 mm diameter makes it a versatile choice for a wide range of small to medium scale milling tasks.

The trace of land feature enhances surface finish quality, making this end mill a dependable option for professionals who value precision and repeatable results in every job.

• Three-flute design for stable cutting: Reduces chatter and enables smoother cuts with reliable chip evacuation, helping you maintain consistent tolerances on non-ferrous workpieces.
• 38° helix for efficient chip control: Optimizes cutting in softer metals, promoting clean entry, effective chip removal, and minimized built-up edge for steady performance.
• Trace of land for superior surface finish: Adds a refined cutting edge that delivers better surface quality and repeatable finishes across multiple passes.

This end mill is built to support professional workflows—from quick setup to repeatable results. Its carbide construction and optimized geometry work together to provide reliable performance across non-ferrous materials, helping you achieve smooth finishes, tighter tolerances, and dependable tool life on aluminum, brass, copper, and similar alloys.
