Spiral router bit Finishing VHM Z2 D6 I27 L70 S6 RH negative

Solid carbide spiral end mill 6x27 mm from the SB51 series – ideal edge quality and high efficiency

Index: SB51.06.027.070.06R

High-performance spiral end mill made from a solid sintered carbide (VHM) from the SB51 line, designed for precise cutting, shaping, grooving, and slotting on overhead spindle milling machines and CNC centres. The tool features a two-flute spiral geometry in a Z2 negative arrangement, which forces effective chip removal downwards. The use of high-quality micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's longevity. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent surface finish standard on the machined material.

Construction advantages and technical properties:

• Finishing geometry 2 (downward cutting): Two cutting edges directing the chips downwards ensure a clean top edge of the workpiece and effectively prevent chipping of veneer or laminate.
• Monolith of Premium sintered carbide (VHM): The rigid, monolithic structure prevents deformation of the end mill under heavy loads, allowing for tight dimensional tolerances to be maintained.
• Option for PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of cutting 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 wear on the spindle taper.
• Dynamic balancing to norm G2.5: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and vibration generated at high speeds (up to 18,000 RPM).

Purpose and range of applications:

The tool is intended for cutting, peripheral milling, grooving, slotting, and finishing edge operations.

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