Spiral router bit Finishing VHM Z2 D5 I17 L50 S5 RH positive

Two-flute spiral end mill 5x17 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.05.017.050.05R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SB01 line, designed for precise cutting, shaping, and finishing tasks on surface milling machines and CNC centres. The tool utilises a two-flute spiral geometry in a 2 positive configuration, which enforces effective chip removal upwards. The use of high-quality micrograin carbide ensures high resistance to abrasive wear and significantly extends the durability of the cutting edge. The ground shank in a tolerance class of H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent standard of finish on the workpiece material.

Design advantages and technical properties:

• Z2 finishing geometry (upward eject): Two cutting edges ensure high cutting efficiency, ideal edge finishing standard, and effective upward chip removal.
• Premium sintered carbide monolith (VHM): Rigid, monolithic construction prevents deformation of the mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of PVD coating application: The option of applying protective layers (e.g. TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the gripping part: The shank surface with a roughness index of Ra ≤ 0.3 µm secures the mill against rotating in the holder and eliminates the risk of wearing the cone in the spindle.
• Dynamic balancing in standard G2.5: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) minimises noise and reduces vibrations generated at the highest speeds (up to 18,000 RPM).

Intended use and application range:

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

It performs excellently in machining materials such as: soft and hard wood, raw MDF board, plywood, and raw particle board.
