Spiral router bit Finishing VHM Z2 D4 I15 L60 S8 RH negative

VHM spiral end mill double-edged 4x15 mm from the SB51 series – perfect edge quality and high performance

Index: SB51.04.015.060.08R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SB51 series, designed for precise cutting, contouring, grooving, and notching on top spindle mills and CNC centres. The tool features a double-edged spiral geometry in a Z2 configuration with a negative layout, which ensures effective chip removal downwards. The use of high-quality micro-grain carbide provides high resistance to abrasive wear and significantly extends cutting edge durability. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent finish standard of the machined material.

Structural advantages and technical specifications:

• Finishing geometry 2 (downward discharge): Two cutting edges directing the chips downwards ensure a clean top edge of the workpiece and effectively prevent the lifting of veneer or laminate.
• Monolith of Premium sintered carbide (VHM): The rigid, monolithic construction prevents deformation of the mill during operations under high forces, allowing for narrow dimensional tolerances to be maintained.
• Possibility of PVD coating application: The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the clamping section: The shank surface with a roughness index of Ra ≤ 0.3 µm secures the mill against rotation in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing in standard G2.5: Certified static-dynamic balancing in a refined class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at maximum speeds (up to 18,000 RPM).

Purpose and area of application:

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

It performs excellently in the machining of materials such as: soft and hardwood, raw and laminated MDF board, raw and laminated plywood, and raw and laminated chipboard.
