Spiral router bit Roughing VHM Z3 D16 I95 L150 S16 RH positive NaDia

Three-flute roughing end mill VHM for lock sockets

Index: SF30.16.095.150.16XR

Industrial spiral end mill made from solid sintered carbide (VHM) from the SF30 series, designed for efficient rough machining and deep mortising of door lock sockets on CNC machining centres and gantry mills. The tool features a three-flute spiral geometry with a roughing profile (Z3) and upward chip ejection (positive), ensuring effective chip removal and a clean lower edge of the workpiece. The roughing teeth with a chip breaker reduce cutting forces and lower spindle load. The extended body with a taper allows for deep penetration into the material without the risk of rubbing or burning the edges. The ground shank in H6 precision class minimizes 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 upward, and ensures a clean lower edge of the machined element.
• Solid sintered carbide (VHM): The rigid monolithic construction reduces tool deflection under load and allows for high dimensional precision.
• Extended body with undercut: The undercut non-cutting section provides technological clearance, allowing for deep mortising of lock sockets without the risk of the body rubbing against the material walls.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards eliminates vibrations and reduces noise at high rotational speeds.

Intended use and application range:

The tool is designed for mortising and rough milling lock sockets as well as cutting and deep penetration in door wings on CNC machines.

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