Spiral router bit for aluminum & plastics with 90° V-point VHM Z1 D5 I25 L100 S8 RH Finishing positive

Single-edged spiral cutter VHM with 90° reaming blade for aluminium and plastics with upward chip removal – clean lower edge

Index: SP15.05.025.100.08R

Industrial single-edged spiral cutter made from solid carbide (VHM) with positive geometry (upward chip removal) and a front reaming blade at a 90° angle (V-point). The special design of the front facilitates direct plunging into the material along the Z-axis without the need for ramping motion, reducing cutting resistance and the risk of surface damage upon entry. The right-hand spiral arrangement directs chips upwards, ensuring the cleanliness of the lower edge of the workpiece. Designed for efficient cutting, welding, grooving, and slotting in aluminium, ALU/PVC profiles, plastics, and composites on CNC machining centres and overhead spindle milling machines. Single-edged finishing geometry (Z1) combined with a polished flute protects the cutting area from overheating. A ground shank in the H6 accuracy class eliminates radial runout, protecting the machine’s drive system.

Design advantages and technical properties:

• 90° V-point front blade: The reaming blade allows for quick spot drilling and seamless entry into the material along the Z-axis.
• Positive geometry (upward chip removal): The right-hand chip channel removes debris from the base of the material, protecting the lower edge from damage.
• Z1 single-edged design: The single cutting edge provides a wide chip space, reducing cutting resistance and temperature in the cutting zone.
• Polished chip flute: The mirror finish of the spiral effectively limits the risk of the body becoming clogged with flexible aluminium chips.
• Monolithic carbide (VHM): The rigid structure of the monolith reduces vibrations and guarantees dimensional stability in difficult materials.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing to class G2.5: Balancing in accordance with ISO standards ensures vibration-free operation at high speeds.

Application and usage range:

The tool is designed 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® sheets, ALUCOBOND® A2, plastics, and composites like CORIAN® and HPL.
