Spiral router bit Finishing VHM Z1 D4 I15 L50 S4 RH positive

VHM spiral end mill single-edged 4x15 from the SA01 series – perfect edge quality and high processing efficiency

Index: SA01.04.015.050.04R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SA01 line, designed for precise cutting, shaping and finishing tasks on overhead spindle milling machines and CNC centres. The tool uses a uniform spiral geometry in configuration Z1 with a positive arrangement, which enforces effective chip removal upwards. The use of high-quality micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's durability. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent standard of finish on the workpiece.

Design advantages and technical properties:

• Finishing geometry 1 (upward chip evacuation): Polished chip channel combined with a single cutting edge facilitates smooth evacuation of material upwards while maintaining minimal cutting resistance.
• Premium sintered carbide monolith (VHM): Stiff, monolithic construction prevents deformation of the mill during operation under high force, allowing for tight dimensional tolerances.
• Ability to apply PVD coating: The option to apply protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extensions of edge life, drastically reduces friction and protects against overheating.
• Low roughness of the shank: Shank surface with a roughness indicator of Ra ≤ 0.3 µm protects the mill from rotating in the holder and eliminates the risk of wearing on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in an advanced class G2.5 (according to ISO/EN) reduces noise and vibrations generated at maximum speeds (18,000 – 24,000 RPM).

Intended use and scope of application:

The tool is intended for cutting operations, contour milling, and finishing edge machining.

It performs excellently in machining materials such as soft and hard wood, raw MDF boards, plywood, and raw particleboard.
