Spiral router bit Finishing VHM Z3 D14 I50 L110 S14 RH negative

VHM three-flute spiral end mill 14x50 mm from the SC51 series – ideal edge quality and high efficiency 

Index: SC51.14.050.110.14R

High-performance spiral end mill made from solid monolithic tungsten carbide (VHM) from the SC51 line, designed for precise cutting, contouring, grooving, and finishing on vertical milling machines and CNC centres. The tool employs a three-flute spiral geometry in Z3 configuration with a negative setup that facilitates effective chip removal downwards. The use of high-quality micrograin carbide ensures high wear resistance and significantly extends the lifespan of the cutting edge. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent standard of finish on the machined material.

Design advantages and technical properties:

• Z3 finishing geometry (downward chip removal): Three cutting edges directing the material downwards ensure a clean upper edge of the workpiece, no tearing, and effectively prevent lifting of veneer or laminate at high feed rates.
• Monolith of Premium sintered carbide (VHM): Rigid, monolithic construction prevents deformation of the mill during operation under high force, allowing for tight dimensional tolerances to be maintained.
• Possibility of applying PVD coating: The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the shank: The shaft surface with a roughness indicator of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of wearing the taper in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) eliminates noise and reduces 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, and edge finishing.

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