Spiral router bit Finishing VHM Z3 D10 I42 L90 S10 RH negative

VHM three-flute spiral cutter 10x42 mm from the SC51 series – ideal edge quality and high efficiency 

Index: SC51.10.042.090.10R

High-performance spiral cutter made from solid sintered carbide (VHM) from the SC51 line, designed for precise cutting, profiling, grooving, and finishing on overhead spindle milling machines and CNC centres. The tool employs a three-flute spiral geometry in a Z3 negative configuration, which enforces 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 lifespan. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent finish standard for the machined material.

Construction advantages and technical properties:

• Z3 finishing geometry (downward chip evacuation): Three cutting edges directing the chips downwards ensure a clean upper edge of the raw material, no tear-outs, and effectively prevent veneer or laminate lifting at high feed rates.
• Premium sintered carbide monolith (VHM): The rigid, monolithic construction prevents cutter deformation when working under high forces, allowing for tight dimensional tolerances to be maintained.
• PVD coating application option: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of the 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 chuck and eliminates the risk of wear on the spindle taper.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing to an enhanced class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds (up to 18,000 RPM).

Intended use and range of applications:

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

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