GEK 2B R2.0xD4x8x100- 2 flute

Description

GEK 2B R2.0xD4x8x100- 2 flute carbide ball nose 65 hrc is a specialized extra-long reach cutting tool designed for deep cavity machining and precision 3D profiling. This premium solid carbide ball nose end mill features a Radius of 2.0mm (R2.0), which corresponds to a 4.0mm cutting diameter. It is constructed with a consistent 4mm shank (D4), a compact 8mm flute length, and an extended Overall Length (OAL) of 100mm. Rated for extreme hardness up to 65 HRC, this tool is the ultimate solution for milling hardened tool steels, die steels (like D2 and H13), and heat-treated alloys without the risk of tool deflection or breakage.

The standout feature of this tool is the combination of a short flute length (8mm) with a long overall length (100mm). Machinists looking for an extra long ball nose end mill often face issues with vibration. However, by keeping the cutting flute short, this long reach carbide cutter maintains maximum core strength and rigidity. This design is specifically engineered for reaching deep into mold cores and pockets where standard length tools cannot access. The 2-flute geometry provides ample chip clearance, which is essential when performing deep 3D contouring or complex engraving operations to prevent chip packing.

Ideal for the die and mold industry, this R2.0 ball mill excels in semi-finishing and finishing applications. The high hardness carbide substrate, often paired with a Blue Nano or heat-resistant coating, allows for high-speed dry machining. Customers frequently search for a CNC ball mill for hardened steel that provides a superior surface finish, reducing the need for manual bench polishing. The 4mm shank fits standard ER collets and hydraulic chucks, ensuring secure clamping and low runout.

Whether you are machining complex turbine blades, medical implants, or deep injection molds, the GEK 2B R2.0xD4x8x100 delivers the precision you need. It bridges the gap between standard tools and expensive custom tooling. If your project requires a long shank ball nose cutter to machine steep walls or deep features in 65 HRC material, this tool offers the durability and performance to get the job done efficiently. Upgrade your CNC setup with this deep reach milling cutter to enhance your capabilities and production speed.
