Spiral router bit Finishing VHM Z3 D16 I55 L110 S16 RH negative

Three-flute VHM spiral cutter 16x55 mm from the SC51 series – ideal edge quality and high efficiency 

Index: SC51.16.055.110.16R

A high-performance spiral cutter made from a solid monolith of cemented carbide (VHM) from the SC51 line, designed for precise cutting, shaping, grooving, and finishing on overhead spindle milling machines and CNC centres. The tool features a three-flute spiral geometry in a Z3 configuration with a negative angle, which forces effective chip removal downwards. The use of high-quality micrograin carbide ensures high resistance to abrasive wear and significantly extends the edge life. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent finish standard on the machined material.

Design advantages and technical properties:

• Z3 finishing geometry (chip removal downwards): Three cutting edges direct the chips downwards, ensuring a clean top edge of the workpiece, preventing tears, and effectively preventing lifting of veneer or laminate at high feed speeds.
• Monolith of Premium cemented carbide (VHM): The rigid, monolithic construction prevents deformation of the cutter during operation under high force, allowing for tight dimensional tolerances.
• Possibility of PVD coating: The option to apply 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 shank surface with a roughness index of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standards: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Purpose and range of use:

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

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