Two-flute solid carbide spiral end mill 5x17 mm from the SB51 series – ideal edge quality and high performance

Index: SB51.05.017.060.06R

This high-performance spiral end mill is made from a solid monolith of sintered carbide (VHM) from the SB51 line, designed for precise cutting, profiling, grooving, and notching on above-spindle mills and CNC centres. The tool utilises a two-flute spiral geometry in a Z2 configuration with a negative rake, which forces effective chip removal downwards. The use of high-grade micrograin 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 of the machined material.

Design advantages and technical properties:

• Finishing geometry 2 (downward eject): Two cutting edges directing the chips downwards ensure a clean upper edge of the machined material and effectively prevent chip lifting from the veneer or laminate.
• Premium sintered carbide monolith (VHM): The rigid, monolithic construction prevents deformation of the mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of applying PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for 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 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 in G2.5 standard: Certified static-dynamic balancing in an exceptional class G2.5 (according to ISO/EN) minimises noise and reduces vibrations generated at high speeds (up to 18,000 RPM).

Intended use and scope of application:

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

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