Shars 8 PCS 1/16″-3/8″ HSS Corner-Rounding End Mill Set 404-5826 S

Description

Product Overview

The Shars 8‑piece High Speed Steel (HSS) corner‑rounding end mill set is engineered to meet the demanding requirements of modern machining operations. Covering a comprehensive size range from 1/16″ through 3/8″, the set provides the flexibility needed for a variety of applications, from fine detail work to larger radius cuts. Each cutter is a single‑end, 4‑flute tool with a Weldon shank, delivering excellent rigidity and run‑out control. The uncoated HSS material offers a balance of hardness and toughness, allowing the tools to maintain sharp cutting edges while resisting wear in both ferrous and non‑ferrous environments. The design incorporates a center‑cut geometry that reduces chip evacuation issues and improves surface finish. All eight pieces are packaged together for convenient inventory management and quick tool changes, making the set an ideal addition to any CNC milling cell or manual machining station.

Usage

These corner‑rounding end mills excel in a wide range of industrial and scientific settings. They are particularly well‑suited for aerospace component fabrication, automotive part machining, medical device manufacturing, and prototype development where precise radius profiles are critical. The tools can be employed on steel, stainless steel, aluminum, brass, copper, and many alloyed materials, delivering consistent performance across diverse substrates. In CNC environments, the 4‑flute design enables high feed rates while maintaining stability, reducing cycle times and improving overall productivity. For manual milling operations, the Weldon shank provides a secure grip in collet or chuck holders, minimizing vibration and extending tool life. The ability to resharpen the cutters without altering their geometry means that users can achieve cost‑effective, repeatable results over many production runs.

Why Choose Us

Choosing the Shars corner‑rounding end mill set means investing in a product backed by rigorous quality assurance processes. Each cutter undergoes precision grinding and inspection to meet tight dimensional tolerances, ensuring that the radius profile is accurate to within microns. The HSS material is sourced from reputable steel manufacturers, providing a consistent hardness that resists chipping and deformation even under heavy cutting loads. Because the tools are uncoated, they can be resharpened multiple times without the risk of coating delamination, offering a sustainable solution that reduces waste. Shars also provides responsive technical support and a clear warranty policy, giving customers confidence that any issues will be addressed promptly. The set’s comprehensive size range eliminates the need to stock multiple individual end mills, simplifying inventory and reducing storage costs.

FAQ

Can these end mills be used on aluminum?

Yes, the HSS construction and 4‑flute geometry make the cutters suitable for aluminum and other non‑ferrous alloys, providing clean cuts and good surface finish.

How often can the tools be resharpened?

Because the cutters are uncoated, they can be resharpened multiple times—typically up to five or more cycles—while maintaining the original radius profile.

What is the recommended spindle speed for these end mills?

For most steel applications, a spindle speed between 4,000 and 6,000 RPM is recommended; for softer materials like aluminum, speeds up to 10,000 RPM can be used, always adhering to the machine’s capability and safety guidelines.

Do the tools come with a warranty?

Shars offers a limited warranty covering manufacturing defects, and the company’s customer service team is available to assist with any performance or fit‑related concerns.

Are the shanks compatible with standard collets?

Yes, the Weldon shank is designed to fit standard collet sizes and can be used in most CNC machines and manual milling heads without modification.
