Spiral router bit Roughing VHM Z3 D14 I95 L150 S14 RH positive

Three-flute roughing spiral end mill VHM for lock sockets

Index: SF30.14.095.150.14R

Industrial spiral end mill made from solid sintered carbide (VHM) from the SF30 series, designed for efficient rough machining and deep pocketing for door locks on CNC machining centres and overhead spindle mills. The tool features a three-flute spiral geometry with a roughing profile (Z3) and upward chip removal (positive), which ensures effective chip evacuation and a clean lower edge of the material. The rough cutting edge with chip breaker reduces cutting resistance and minimizes spindle loading. The extended body with taper allows for deep penetration into the material without the risk of rubbing or burning the edges. The ground shank in H6 accuracy class eliminates radial runout, protecting the drive system and ensuring process stability.

Design advantages and technical properties:

• Three-flute roughing design Z3 (positive): Dedicated roughing profile breaks chips into small fragments, lowers cutting resistance, effectively evacuates chips upward, and guarantees a clean lower edge of the machined part.
• Solid sintered carbide (VHM): Rigid monolithic construction reduces tool deflection under load and maintains high dimensional precision.
• Extended body with counter-bore: The counter-bored non-cutting part provides technological clearance, allowing for deep pocketing of lock sockets without the risk of the body rubbing against the walls of the material.
• Low handle 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 class G2.5: Balancing according to ISO standards eliminates vibrations and reduces noise at high rotational speeds.

Purpose and application range:

The tool is intended for pocketing and rough milling of sockets for door locks as well as for cutting and deep penetration in door leaves 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.
