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

Three-flute roughing spiral end mill VHM for lock pockets

Index: SF30.16.095.150.16R

Industrial spiral end mill made from solid sintered carbide (VHM) from the SF30 series, designed for efficient rough machining and deep pocketing of lock 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) and chip evacuation upwards (positive), ensuring efficient chip removal and a clean bottom edge of the material. The roughing tooth with chip breaker reduces cutting resistance and lowers spindle load. The extended body with a taper allows deep penetration into the material without the risk of rubbing or burning the edges. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the drive system and providing process stability.

Design advantages and technical properties:

• Three-flute roughing design Z3 (positive): Custom roughing profile breaks the chip into small pieces, reduces cutting resistance, efficiently evacuates chips upwards, and guarantees a clean bottom edge of the processed element.
• Monolithic sintered carbide (VHM): Rigid monolithic construction reduces tool deflection under load and allows for maintaining high dimensional precision.
• Extended body with undercut: The undercut non-cutting part provides technological clearance, allowing deep pocketing of lock holes without the risk of the body rubbing against the material walls.
• Low roughness of the shank (Ra ≤ 0.3 µm): Ground shank surface 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.

Application and scope of use:

The tool is designed for operations of pocketing and rough milling of lock pockets for door locks, as well as cutting and deep pocketing 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.
