Spiral router bit Roughing VHM Z3 D12 I95 L150 S12 RH positive

Three-fluted roughing spiral cutter VHM for lock sockets

Index: SF30.12.095.150.12R

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

Design 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 lower edge of the machined part.
• Solid carbide (VHM): The rigid monolithic design reduces tool deflection under load and maintains high dimensional precision.
• Extended body with counterbore: The counterbored non-cutting section provides technological clearance, allowing for deep channelling of lock sockets without the risk of rubbing the body against the walls of the material.
• Low roughness of the shank (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 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 channelling and rough milling of sockets for door locks, as well as cutting and deep penetration in door leaves on CNC machines.

It works excellently for machining materials such as: soft and hardwood, plywood, as well as raw particle board and raw MDF.
