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

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

Index: SC51.16.055.110.16XR

High-performance spiral end mill made from solid sintered carbide (VHM) from the SC51 line, designed for precise cutting, shaping, grooving, and finishing on vertical milling machines and CNC centres. The tool employs a three-flute spiral geometry in a Z3 configuration with a negative pitch, which facilitates 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 in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent standard of finish on the machined material.

Construction advantages and technical properties:

• Z3 finishing geometry (downward chip ejection): Three cutting edges directing the chips downwards ensure a clean top edge of the workpiece, preventing tearing and effectively eliminating the risk of lifting veneer or laminate at high feed rates.
• Monolithic Premium sintered carbide (VHM): The rigid, monolithic structure prevents distortion of the end mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of applying PVD coating: The option to apply protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extensions of the edge life, reduces friction, and protects against overheating.
• Low roughness of the clamping part: The shank surface with a roughness index of Ra ≤ 0.3 µm protects the end mill from spinning in the holder and eliminates the risk of wear on the spindle taper.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and decreases vibrations generated at high speeds (up to 18,000 RPM).

Intended use and application range:

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

It performs excellently 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.
