Spiral router bit Finishing VHM Z2 D12 I52 L100 S12 RH positive

VHM spiral end mill double-edged 12x52 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.12.052.100.12R

High-performance spiral end mill made from a solid sintered carbide monolith (VHM) from the SB01 line, intended for tasks involving precise cutting, formatting, and finishing on overhead spindle mills and CNC centres. The tool employs a double-edged spiral geometry in 2 positive layout configuration, which forces efficient chip removal upwards. The use of high-quality micrograin 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 of the machined material.

Design advantages and technical properties:

• Z2 finishing geometry (upward chip removal): Two cutting edges guarantee high cutting efficiency, ideal edge finish standard, and efficient chip removal upwards.
• Monolith of Premium sintered carbide (VHM): Rigid, monolithic construction prevents deformation of the mill under high force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of applying a PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the shank: The surface of the shank with a roughness indicator of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of wearing the cone in the spindle.
• Dynamic balancing to G2.5 standards: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and minimises vibration generated at high speeds (up to 18,000 RPM).

Intended use and scope:

The tool is designed for cutting operations, contour milling, and finishing edge processing.

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