Micro 100 Corner Rounding End Mill CRE-125-020 .060 Fl .020 Radius

Description

Product Overview

The Micro 100 CRE-125-020 Corner Rounding End Mill is engineered for high‑precision machining of tight radii in a wide range of metal substrates. Featuring a .060 inch flute length and a .020 inch radius, the tool delivers clean, burr‑free corners that meet demanding engineering tolerances. Constructed from high‑speed steel with an optional AlTiN coating, the mill offers excellent wear resistance while the uncoated version provides a cost‑effective solution for general‑purpose applications. The double‑ended design maximizes productivity by allowing two cutting edges to be used without re‑orienting the workpiece, and the 1/8 inch shank coupled with a 2 inch overall length ensures rigidity and stability throughout the machining process. Detailed specifications include a 2.6 × 0.2 × 0.2 inch overall size, a lightweight 0.16 oz mass for easy handling, and a maximum lead‑in length of .005 inch to reduce tool deflection.

Designed with a 1‑degree maximum flare tangent at both pilot and shoulder, the mill eliminates steps and burrs that commonly arise from traditional end‑mill geometries. This precise geometry, combined with the ability to cut exclusively on the radius, makes the CRE‑125‑020 an ideal choice for aerospace components, automotive brackets, and intricate molds where surface finish and dimensional accuracy are paramount. The tool’s 2‑inch overall length (OAL) provides a balanced feel in the collet, reducing vibration and extending tool life even under heavy cutting conditions.

Usage

In aerospace manufacturing, the CRE‑125‑020 excels at creating smooth corner transitions on turbine blades, structural brackets, and fastener housings where aerodynamic performance depends on flawless edges. Its compact size and precise radius enable operators to machine tight spaces without sacrificing material removal rates, making it a preferred tool for both prototype development and high‑volume production runs.

Automotive engineers rely on this end mill for fabricating engine components, suspension parts, and interior trim pieces that require consistent corner radii to improve fit‑and‑finish and reduce post‑machining deburring. The tool’s double‑ended configuration reduces setup time, allowing technicians to switch between cutting edges quickly, thereby increasing overall shop floor efficiency. Additionally, the mill is well‑suited for general manufacturing environments, including CNC milling of aluminum, stainless steel, and titanium alloys, where its robust construction and stable shank geometry help maintain tight tolerances over extended production cycles.

FAQ

What materials can the CRE‑125‑020 safely machine?

The end mill is suitable for a broad range of metals, including aluminum alloys, stainless steel, carbon steel, and titanium. When paired with the optional AlTiN coating, it can also handle more abrasive materials such as Inconel and hardened steels, extending tool life while maintaining dimensional accuracy.

How does the double‑ended design improve workflow?

Each end of the tool features an identical cutting geometry, allowing the operator to flip the mill and use the opposite edge without removing the tool from the spindle. This reduces non‑productive time associated with tool changes, especially in high‑volume CNC operations where every second counts.

Can the tool be used for both roughing and finishing passes?

Yes. The CRE‑125‑020’s geometry is optimized for both roughing and finishing. The short flute length provides rigidity for heavy material removal, while the precise radius and fine edge finish enable high‑quality finishing passes that meet tight tolerance requirements.

What is the recommended spindle speed and feed rate?

Recommended spindle speeds range from 8,000 to 12,000 RPM for aluminum and up to 6,000 RPM for harder steels. Feed rates should be adjusted based on material hardness, typically between 0.001 and 0.003 inches per tooth. Always refer to the machine’s capability chart and perform a test cut to fine‑tune parameters for optimal performance.

Is there a warranty or after‑sales support?

Micro 100 offers a limited one‑year warranty covering manufacturing defects. In addition, our dedicated support team is available to assist with troubleshooting, tool optimization, and replacement parts, ensuring you experience minimal disruption and maximum productivity.
