Spiral router bit Finishing VHM Z3 D18 I55 L110 S18 RH positive

VHM three-flute spiral end mill 18x55 mm from the SC01 series – perfect edge quality and high machining performance

Index: SC01.18.055.110.18R

This high-performance spiral end mill is made from a solid sintered carbide (VHM) monolith from the SC01 line, intended for tasks related to precise cutting, shaping, and finishing on overhead spindle milling machines and CNC centres. The tool features a three-flute spiral geometry in a Z3 configuration with a positive layout, which compels efficient chip removal upwards. The use of high-grade micro-grain carbide ensures high wear resistance and significantly extends the cutting edge's lifespan. A ground shank with a tolerance class of H6 eliminates radial run-out, protecting the spindle bearing assembly and guaranteeing an excellent finish standard for the machined material. 

Design advantages and technical properties:

• Finishing geometry Z3 (upward chip removal): Three cutting edges ensure very high cutting efficiency, allow for operation at higher feed speeds, provide an ideal edge finishing standard, and facilitate the efficient upward removal of chips.
• Premium sintered carbide monolith (VHM): The rigid, monolithic structure prevents deformation of the end mill during high-force operations, allowing for tight dimensional tolerances to be maintained.
• Possibility of applying PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) enables 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 end mill from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the high class of G2.5 (according to ISO/EN) minimizes noise and reduces vibrations generated at the highest speeds (up to 18,000 RPM).

Intended use and application range:

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

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