F&D Tool Company 34541-CX512 Corner Rounding End Mills, Metric, Cobalt, 8 mm Radius, 3/4″ Shank Diameter, 1.125″ Largest Diameter, 3.25″ Overall Length

Description

Product Overview

The F&D Tool Company Corner Rounding End Mill is a precision‑engineered cutting tool designed for high‑performance machining of metal components. Constructed from premium cobalt alloy, the tool offers exceptional hardness, wear resistance, and heat tolerance, allowing it to maintain sharp cutting edges even under demanding conditions. With an 8 mm radius on the cutting tip, the end mill creates smooth, accurate corner transitions that are essential for aerospace, automotive, and high‑precision equipment manufacturing. The 3/4″ shank provides a secure, rigid connection to standard CNC spindle holders, while the overall length of 3.25″ ensures sufficient reach for deep pocketing and complex geometry. The tool’s geometry is optimized for reduced chip load, minimizing vibration and extending tool life. Detailed specifications include a metric thread, a maximum cutting diameter of 1.125″, and a compact overall length that fits most modern machining centers.

Usage

This end mill excels in a variety of industrial applications where precise corner rounding is required. It is ideally suited for CNC milling of hardened steels, stainless steels, titanium alloys, and nickel‑based superalloys, making it a versatile choice for aerospace component fabrication, automotive engine part machining, and medical device manufacturing. The tool’s cobalt composition allows it to operate at higher cutting speeds without loss of rigidity, reducing cycle times and improving productivity. Users can employ the mill in both roughing and finishing passes, taking advantage of its ability to produce clean, burr‑free edges that reduce post‑processing work. The 3/4″ shank ensures compatibility with most standard collet systems, enabling quick tool changes and minimizing downtime. Its compact length makes it suitable for tight‑space machining, such as internal corners of complex molds and intricate aerospace brackets. The end mill also performs well in high‑speed machining (HSM) environments, where its thermal stability helps maintain dimensional accuracy.

FAQ

What materials can this end mill effectively machine?

The Corner Rounding End Mill is designed for high‑performance machining of hardened steels, stainless steels, titanium alloys, and nickel‑based superalloys. Its cobalt alloy construction allows it to maintain cutting efficiency at elevated temperatures, making it suitable for demanding aerospace and automotive applications where material toughness is critical.

How does the 8 mm radius affect the final part quality?

The 8 mm radius provides a precise, smooth transition between intersecting surfaces, eliminating sharp edges that can cause stress concentrations. This radius is ideal for components that require rounded corners for aerodynamic performance, ergonomic handling, or compliance with industry standards. The result is a part that meets exact dimensional tolerances with minimal need for secondary deburring.

Can this tool be used in high‑speed machining (HSM) environments?

Yes. The cobalt alloy’s high thermal conductivity and heat‑resistant properties enable the end mill to operate at higher spindle speeds without losing rigidity. This capability reduces cycle times while maintaining surface finish quality, making the tool an excellent choice for high‑speed production lines.

What support does F&D Tool Company provide for tool selection and setup?

F&D Tool Company offers a dedicated engineering support team that assists customers with tool selection, optimal cutting parameters, and machine setup. Whether you need guidance on feed rates, spindle speeds, or coolant strategies, our experts provide tailored recommendations to maximize tool performance and longevity.

Is the tool compatible with standard CNC collet sizes?

The end mill features a 3/4″ (19.05 mm) shank, which is compatible with the most common CNC collet sizes, including 19 mm and 20 mm. This compatibility ensures quick tool changes and reduces the need for specialized adapters, streamlining workflow in mixed‑tool environments.
