EM-RC2 1/16″ Radius Corner Rounding End Mill 3/8″ HSS Shank

Description

Product Overview

The EM-RC2 corner rounding end mill is engineered for precision machining where clean, rounded corners are essential. Constructed from high speed steel (HSS), this tool offers superior wear resistance and maintains sharp cutting edges even under demanding conditions. The 1/16″ radius design provides a subtle yet effective material removal profile, ideal for creating smooth transitions between intersecting surfaces. With a 3/8″ shank, the mill fits securely into standard collet chucks, ensuring stability and reducing vibration during high‑speed operations. Its overall length of 2½” and maximum cutting diameter of 7/16″ make it versatile for a range of workpiece sizes, from small components to larger assemblies. The compact geometry allows access to tight spaces where larger tools cannot reach, while the robust HSS material guarantees longevity and consistent performance. Designed for both CNC and manual milling applications, the EM-RC2 delivers reliable results across a variety of industries, including aerospace, automotive, and general manufacturing.

Usage

This end mill excels in environments where precise corner rounding is required, such as aerospace component fabrication, automotive part machining, and toolroom prototyping. It is particularly effective on materials like aluminum, stainless steel, brass, and mild steel, providing clean cuts without excessive burr formation. In CNC milling centers, the EM-RC2 can be programmed for high‑speed, high‑precision passes, reducing cycle times while maintaining surface integrity. For manual milling, the tool’s balanced weight and ergonomic design allow operators to achieve consistent results with minimal effort. The 3/8″ shank ensures compatibility with most standard collet sizes, making tool changes quick and straightforward. Whether used for creating fillets on machined parts, smoothing internal corners, or preparing surfaces for subsequent finishing operations, this end mill offers the flexibility needed for diverse manufacturing workflows.

FAQ

What materials can the EM-RC2 safely machine?

The EM-RC2 is suitable for a wide range of metals, including aluminum alloys, stainless steel, carbon steel, brass, and copper. Its high speed steel composition allows it to handle both soft and harder materials while maintaining a sharp cutting edge.

Can this end mill be used in high‑speed CNC machines?

Yes. The tool’s HSS material and precise heat‑treatment enable it to operate at high spindle speeds without losing rigidity. When paired with appropriate feed rates and coolant, it performs reliably in modern CNC milling centers.

How do I determine the optimal feed and speed settings?

Optimal parameters depend on the workpiece material, desired surface finish, and machine capabilities. As a starting point, use a spindle speed of 8,000–12,000 RPM for aluminum and 4,000–6,000 RPM for steel, adjusting feed per tooth (FPT) between 0.001–0.003 in. Fine‑tune based on chip formation and tool wear observations.

Is the EM-RC2 compatible with standard collet sizes?

Yes. The 3/8″ shank is designed to fit common collet sizes ranging from 1/4″ to 1/2″, ensuring easy integration into most milling setups without the need for special adapters.

What warranty does the product include?

We provide a one‑year limited warranty covering material defects and premature wear under normal operating conditions. Should any issue arise, contact our support team for a replacement or repair solution.
