Description
The ITC Carbide End Mill Corner Radius 3051 is a precision carbide end mill designed for non‑ferrous machining. This 3‑flute tool features a 55° helix, a trace of land, and a defined corner radius (R5) on a 20 mm diameter body to deliver stable cuts, efficient chip evacuation, and a consistent, high‑quality edge on aluminum, copper, and brass. Built for engineers, machinists, and shop floors that demand accuracy and reliability, it helps you achieve precise corners and smooth finishes with every pass.
- Corner Radius R5 for Repeatable Fillets: Delivers a precise corner radius on every pass, enabling repeatable, clean corners and reducing post‑machining finishing steps.
- 55° Helix for Efficient Non‑Ferrous Cutting: The 55° helix promotes fast chip evacuation and smoother cutting in aluminum, copper, and brass, helping maintain dimensional accuracy and a superior surface finish.
- Trace of Land and Radius for Edge Stability: The trace of land combined with the radius preserves edge geometry, reduces rubbing, and yields a consistently smooth surface finish.
This end mill is built to deliver dependable results across non‑ferrous materials. The carbide body and optimized geometry help you maintain tight tolerances, reduce rework, and achieve smooth, accurate finishes on every part. Designed for use in CNC mills and similar equipment, it supports efficient production cycles, lower downtime, and reliable performance in demanding shops.
