.500″ 1/2″ Radius HIGH Speed Steel Corner Rounding END Mill 1″ Shank

Description

Product Overview

The .500″ 1/2″ radius high speed steel (HSS) corner rounding end mill is a precision‑engineered cutting tool designed for demanding CNC milling applications. Constructed from premium HSS, the tool offers superior hardness, wear resistance, and heat tolerance, ensuring consistent performance even under high spindle speeds. Its 1″ shank provides a rigid connection to the machine spindle, reducing deflection and vibration during operation. The cutter features a 4‑flute geometry that balances chip evacuation with surface finish quality, while the overall length of 4‑1/8″ allows for deep material engagement without compromising stability. This end mill is ideal for creating smooth, rounded corners on a variety of workpieces, from aerospace components to automotive parts, delivering tight tolerances and a flawless finish.

Usage

Designed for use on CNC milling centers, the corner rounding end mill excels in environments where precision and repeatability are paramount. It is well‑suited for machining aluminum, brass, mild steel, and other non‑ferrous alloys, as well as certain hardened steels when appropriate cutting parameters are applied. The tool’s compact profile makes it perfect for tight‑space applications, such as internal corner rounding in engine blocks, gear housings, and intricate aerospace brackets. Operators can employ the mill in both high‑speed finishing passes and roughing operations, adjusting feed rates and spindle speeds to match material hardness and desired surface quality. Its versatility also extends to prototyping workshops, where rapid iteration and accurate corner formation are essential.

FAQ

What materials can this end mill safely cut?

The tool is suitable for non‑ferrous metals such as aluminum, brass, and copper, as well as mild steel and certain hardened steels when appropriate cutting speeds and feeds are used.

How do I determine the optimal spindle speed for this cutter?

Start with a spindle speed of 12,000–15,000 RPM for aluminum and 8,000–10,000 RPM for steel, adjusting based on chip formation and surface finish observations.

Can the end mill be used for both roughing and finishing passes?

Yes, the 4‑flute geometry allows for versatile use; employ higher feed rates for roughing and lower rates for finishing to achieve the desired surface quality.

What is the recommended coolant type?

Use a water‑soluble coolant for aluminum and a high‑performance oil‑based coolant for steel to improve chip evacuation and extend tool life.

Is there a warranty on this product?

We offer a one‑year limited warranty covering manufacturing defects, backed by responsive customer service to address any issues promptly.
