Spiral router bit Finishing VHM Z3 D12 I35 L83 S12 RH negative

Three-edge spiral end mill 12x35 mm from the SC51 series – ideal edge quality and high efficiency 

Index: SC51.12.035.083.12R

High-performance spiral end mill made from a solid monolith of cemented carbide (VHM) from the SC51 line, intended for precise cutting, shaping, grooving, and finishing on overhead spindle mills and CNC centres. The tool features a three-edge spiral geometry in a Z3 configuration with a negative angle, which ensures effective chip removal downwards. The use of high-quality micrograin carbide provides excellent wear resistance and significantly extends the cutting edge's lifespan. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and ensuring an excellent surface finish of the machined material.

Structural advantages and technical properties:

• Z3 finishing geometry (downward chip removal): Three cutting edges directing the chips downward ensure a clean upper edge of the workpiece, no tearing, and effectively prevent lifting of veneer or laminate at high feed speeds.
• Premium cemented carbide monolith (VHM): Rigid, monolithic construction prevents deformation of the mill during operation under high forces, allowing for the maintenance of tight dimensional tolerances.
• Possibility to apply PVD coating: The option of applying protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extensions of the edge's lifespan, reduces friction, and protects against overheating.
• Low roughness of the shank: The surface of the shank with a roughness index of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing within G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and vibration generated at the highest speeds (up to 18,000 RPM).

Intended use and scope of application:

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

It works excellently in machining materials such as: soft and hard wood, raw and laminated MDF boards, raw and laminated plywood, as well as raw and laminated chipboard.
