Spiral router bit Roughing VHM Z3 D14 I125 L170 S14 RH positive

Three-flute roughing end mill VHM for lock pockets

Index: SF30.14.125.170.14R

Industrial spiral end mill made from solid carbide (VHM) from the SF30 series, designed for efficient rough machining and mortising deep pockets for door locks on CNC machining centres and overhead milling machines. The tool features a three-flute spiral geometry with a roughing profile (Z3) with upward chip evacuation (positive), ensuring efficient chip removal and a clean bottom edge of the material. The roughing tooth design with a chip breaker reduces cutting resistance and decreases spindle load. The extended body with a taper allows for deep penetration into the material without the risk of rubbing or burning the edge. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the drive system and ensuring process stability.

Structural advantages and technical properties:

• Three-flute roughing design Z3 (positive): The dedicated roughing profile breaks the chip into small pieces, reduces cutting resistance, efficiently evacuates chips upwards, and guarantees a clean bottom edge of the machined element.
• Solid carbide (VHM): The rigid monolithic construction reduces tool deflection under load and maintains high dimensional accuracy.
• Extended body with counterbore: The counterbored non-cutting part provides technological clearance, allowing deep mortising of lock pockets without the risk of rubbing the body against the material walls.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards eliminates vibrations and reduces noise at high rotational speeds.

Intended use and application range:

The tool is intended for mortising and rough milling pockets for door locks, as well as cutting and deep penetration into door wings on CNC machines.

It performs excellently when machining materials such as: soft and hard wood, plywood, as well as raw particle board and raw MDF.
