Spiral router bit for aluminum & plastics with 90° V-point VHM Z1 D6 I25 L80 S8 RH Finishing positive

Single-flute VHM spiral mill with a 90° drilling edge for aluminium and plastics with upward chip removal – clean bottom edge

Index: SP15.06.025.080.08R

Industrial single-flute spiral mill made of solid carbide (VHM) with positive geometry (upward chip removal) and a frontal drilling edge inclined at 90° (V-point). The special design of the tip facilitates direct plunging into the material along the Z-axis without the need for ramp movement, reducing cutting resistance and the risk of surface damage upon entry. The right-hand spiral design directs chips upwards, ensuring the cleanliness of the bottom edge of the machined part. Designed for efficient cutting, welding, grooving, and slotting in aluminium, ALU/PVC profiles, plastics, and composites on CNC machining centres and portal milling machines. The single-flute finishing geometry (Z1) combined with the polished flute protects the cutting area from overheating. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Construction advantages and technical properties:

• Frontal V-point 90° edge: The drilling edge allows for quick spot drilling and seamless entry into the material along the Z-axis.
• Positive geometry (upward chip removal): The right-hand chip flutes pull the chips away from the base of the material, protecting the bottom edge from damage.
• Single-flute design Z1: The single cutting edge provides a wide chip space, reducing working resistance and temperature in the cutting zone.
• Polished chip flute: The mirror finish of the spiral effectively reduces the risk of adhering chips from flexible aluminium.
• Solid carbide (VHM): The rigid structure of the solid carbide reduces vibrations and ensures dimensional stability in difficult materials.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the holder and protects the spindle cone from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards guarantees vibration-free operation at maximum speeds.

Purpose and range of application:

The tool is intended for cutting, welding, grooving, and slotting operations in aluminium and plastics on CNC machining centres.

Used for machining materials such as: aluminium, aluminium and PVC profiles, ALUCOBOND® panels, ALUCOBOND® A2, plastics, and composites such as CORIAN® and HPL.
