Spiral router bit Finishing VHM Z2 D4 I15 L50 S4 RH positive

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

Index: SB01.04.015.050.04R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SB01 line, designed for tasks related to precise cutting, formatting, and finishing on vertical milling machines and CNC centres. The tool uses a double-edged spiral geometry in configuration 2 with a positive layout, which forces efficient chip removal upwards. The use of high-quality micrograin carbide ensures high wear resistance and significantly extends the durability of the cutting edge. The ground shank in a tolerance class of H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent finish standard of the machined material.

Design advantages and technical properties:

• Finishing geometry Z2 (upward chip ejection): Two cutting edges ensure high cutting efficiency, ideal edge finish standard, and effective upward chip removal.
• Premium sintered carbide monolith (VHM): Rigid, monolithic construction prevents deformation of the mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• Option for PVD coating application: 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 clamping part: The shank surface with a roughness indicator of Ra ≤ 0.3 µm protects the mill from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in an enhanced class G2.5 (according to ISO/EN) reduces noise and vibrations generated at highest speeds (up to 18,000 RPM).

Intended use and application range:

The tool is intended for operations of cutting, 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 chipboard.
