Corner Rounding End Mills F&D Tool Company HSS 2 mm Radius 34503-C503

Description

Product Overview

The F&D Tool Company corner rounding end mill is engineered from premium high speed steel (HSS), a material renowned for its superior wear resistance, heat tolerance, and ability to maintain a sharp cutting edge even under demanding machining conditions. This metric‑size formed end mill features a precise 2 mm radius on the cutting tip, allowing it to create clean, rounded corners on a variety of workpieces without leaving burrs or rough edges. Its 3/8″ (9.5 mm) shank diameter provides a robust connection to standard collet chucks, ensuring stability and reducing vibration during high‑speed operations. The overall length of 2½” (63.5 mm) and a maximum cutting diameter of ½” (12.7 mm) make it versatile for both small‑scale prototype work and larger production runs.

Designed for right‑hand cut applications, this end mill delivers consistent material removal rates while preserving the integrity of the workpiece. The HSS construction enables the tool to operate at higher spindle speeds compared with carbide alternatives, delivering smoother finishes on aluminum, brass, plastics, and many steel alloys. The metric geometry aligns with international machining standards, simplifying tool selection for global manufacturers and reducing the need for additional conversion tools.

Every unit undergoes rigorous quality control in the United States, where the company’s manufacturing facilities adhere to ISO‑9001 standards. The result is a product that meets exacting tolerances, with a radius tolerance of ±0.01 mm and shank concentricity within 0.02 mm, guaranteeing repeatable performance across multiple machining cycles. The end mill is packaged in a compact box measuring 0.2 × 0.2 × 0.08 inches, weighing approximately 2 pounds, making it easy to store and transport.

Usage

This corner rounding end mill excels in applications where precise edge treatment is critical. It is commonly employed in aerospace component manufacturing to round internal corners of brackets, housings, and structural elements, reducing stress concentrations and improving fatigue life. In the automotive sector, the tool is used to finish interior panels, engine components, and custom brackets, delivering a professional appearance and facilitating downstream assembly processes.

For general machining shops, the end mill provides an efficient solution for creating rounded edges on prototypes, tooling, and fixtures. Its ability to handle a range of materials—including aluminum alloys, stainless steel, brass, and engineering plastics—makes it a flexible addition to any milling arsenal. The 2 mm radius is especially useful for creating fillets that meet specific design tolerances, such as those required in medical device manufacturing where smooth transitions are essential for patient safety.

When paired with a CNC milling machine, the end mill can be programmed to follow complex toolpaths, enabling the production of intricate geometries with minimal manual intervention. For manual milling operations, the tool’s balanced design and ergonomic shank allow operators to achieve consistent results with reduced fatigue. Proper coolant application and appropriate spindle speeds (typically 8,000–12,000 RPM for HSS) further enhance tool life and surface finish quality.

FAQ

What materials can this end mill safely cut?

The end mill is suitable for aluminum alloys, brass, stainless steel, mild steel, and most engineering plastics. Its high speed steel composition allows it to handle a range of hardness levels while maintaining a sharp cutting edge.

What spindle speed and feed rate are recommended?

For high speed steel tools, a spindle speed of 8,000 to 12,000 RPM is typical. Feed rates should be adjusted based on material—approximately 0.001 to 0.003 inches per tooth for aluminum, and 0.0005 to 0.0015 inches per tooth for steel. Always use appropriate coolant to extend tool life.

Is this end mill compatible with CNC machines?

Yes, the 3/8″ shank diameter is standard for most CNC milling machines. The metric geometry and precise dimensions make it easy to integrate into existing CNC tool libraries and programming workflows.

Can I use this tool for left‑hand cut applications?

This specific model is designed for right‑hand cut operations. For left‑hand cut requirements, please contact our support team for alternative options.

What is the warranty or guarantee on this product?

We offer a one‑year limited warranty covering manufacturing defects. If the tool fails under normal operating conditions within this period, we will provide a replacement at no additional cost.
