2HRB R1.5xD4x30x50 2f rib 55

Description

2HRB R1.5xD4x30x50 2f rib 55 is a specialized long-neck carbide tool designed for precision deep-milling applications, distributed exclusively in India by Sukhmani Total Solutions (STS). As the authorized Sole Agent for Changzhou Xute Jifeng Tools Group (Geefun), STS ensures that Indian industries receive genuine, high-performance tooling directly from the manufacturer. This solid carbide rib cutter features a Radius of 1.5mm (R1.5)—which equals a 3.0mm cutting diameter—a reinforced 4mm shank, a relieved Effective Neck Length of 30mm, and a standard Overall Length (OAL) of 50mm.

Through the powerful STS-GEEFUN collaboration, every tool is manufactured on industry-leading 5-axis CNC Grinding Machines from Walter (Germany) and ANCA (Australia). The “Rib” or “Long Neck” geometry is critical for mold makers; the relieved neck allows the cutter to reach 30mm deep into narrow slots and cavities without the shank rubbing against the workpiece walls. To guarantee precision at this depth, STS ensures that every batch undergoes 100% inspection on Zoller (Germany) measuring machines, ensuring tight tolerances and minimal runout.

Rated for materials up to 55 HRC, this tool is the ideal solution for machining pre-hardened tool steels (like P20, NAK80), stainless steel, and cast iron. The 2-flute design offers the perfect balance of core strength and chip clearance, which is essential when rib processing in deep pockets to prevent chip packing. Machinists frequently search for a deep reach ball nose end mill or a long neck carbide cutter to machine complex 3D contours that standard stub-length tools cannot access. The 30mm effective length provides a reach of 10x the cutter diameter, maintaining stability due to the robust 4mm shank.

Sourced from premium micro-grain carbide suppliers like Sandvik or Guhring and coated with heat-resistant Blue Nano or AlTiN, this tool delivers extended life in abrasive conditions. Sukhmani Total Solutions makes these specialized tools available across Pan India, ensuring that whether you are in Ludhiana, Pune, or Chennai, you have access to the best CNC mold making tools. Trust the STS-GEEFUN series for high-quality deep milling that reduces the need for EDM operations and improves your surface finish.
