Spiral router bit Finishing VHM Z2 D3 I12 L60 S8 RH negative

Double-edged VHM spiral end mill 3x12 mm from the SB51 series – ideal edge quality and high efficiency

Index: SB51.03.012.060.08R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SB51 line, designed for precise cutting, shaping, notching, and grooving on overhead spindle milling machines and CNC centres. The tool employs a double-edged spiral geometry in a Z2 negative configuration, which ensures effective chip removal downwards. The use of high-grade micro-grain carbide provides high wear resistance, significantly extending the cutting edge's lifespan. The ground shank with a tolerance class of H6 eliminates radial runout, protecting the spindle bearing assembly and ensuring an excellent surface finish of the machined material.

Design advantages and technical properties:

• Finishing geometry 2 (downward discharge): Two cutting edges directing chips downwards guarantee a clean upper edge of the workpiece and effectively prevent lifting of veneer or laminate.
• Premium sintered carbide monolith (VHM): The rigid, monolithic structure prevents deformation of the end mill under high force, allowing narrow dimensional tolerances to be maintained.
• PVD coating application option: The option to apply protective coatings (including TiSiN or PLATINIUM) allows for multiple extensions of the cutting edge's life, reduces friction, and protects against overheating.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to 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).

Application and scope of use:

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

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