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

VHM two-flute spiral end mill 5x17 mm from the SB51 series – ideal edge quality and high efficiency

Index: SB51.05.017.050.05R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SB51 line, designed for precise cutting, shaping, grooving, and engraving on overhead spindle milling machines and CNC centres. The tool features a two-flute spiral geometry in a Z2 negative arrangement, which forces effective chip removal downwards. The use of high-quality micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's service life. The ground shank with a tolerance class of H6 mitigates radial runout, protecting the spindle bearing system and guaranteeing an excellent finish standard on the machined material.

Structural advantages and technical properties:

• Finishing geometry 2 (downward chip removal): Two cutting edges directing the chips downwards guarantee a clean upper edge of the raw material and effectively prevent the lifting of veneer or laminate.
• Premium sintered carbide monolith (VHM): The rigid, monolithic construction prevents distortion of the end mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• Option for PVD coating: The option for applying protective layers (e.g., TiSiN or PLATINIUM) allows for several times the lifespan of the edge, reduces friction, and protects against overheating.
• Low roughness of the clamping part: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Intended use and application range:

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

It works excellently for machining materials such as: soft and hard wood, raw and laminated MDF board, raw and laminated plywood, and raw and laminated particle board.
