VHM spiral end mill double-edged 4x15 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.04.015.060.08L

High-performance spiral end mill made of solid sintered carbide (VHM) from the SB01 line, designed for tasks involving precise cutting, shaping, and finishing on overhead milling machines and CNC centres. The tool utilises a double-edged spiral geometry in a 2 configuration with a positive layout, which ensures effective chip removal upwards. The use of high-grade micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's durability. 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:

• Z2 finishing geometry (upward discharge): Two cutting edges guarantee high cutting efficiency, ideal edge finish standard, and efficient upward removal of chips.
• Monolithic premium sintered carbide (VHM): The rigid, monolithic construction prevents deformation of the cutter during operation under high forces, allowing for narrow dimensional tolerances to be maintained.
• PVD coating application possibility: The option to apply protective layers (including TiSiN or PLATINIUM) allows for several times the extension of 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 mill from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing in class G2.5: Certified static-dynamic balancing in the highly rated G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Purpose and range of application:

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

It performs excellently in the machining of materials such as: soft and hard wood, raw MDF board, plywood, and raw particle board.
