Three-flute VHM finishing spiral end mill with undercut for 3D models – upwards chip removal

Index: SR02.16.040.150.16R

Industrial three-flute spiral end mill made from solid carbide from the SR02 series, featuring finishing geometry, an undercut body, and upwards chip removal. Dedicated to highly precise finishing machining of 3D shapes, forming deep reliefs and spatial surfaces in aluminium, plastics, and composites. The arrangement of three cutting edges combined with a right-hand screw helix provides high tool rigidity, vibration-free operation, and effectively removes chips from the cutting area. Optimised design with undercut (neck): The body’s narrowing eliminates the risk of tool collision with the material during deep milling, facilitates free chip removal, and reduces friction, protecting the workpiece from overheating. The ground shank in H6 accuracy class eliminates radial runout, protecting the machine drive system.

Key technical parameters and properties:

• Optimised design with undercut (neck): The narrowing of the body eliminates the risk of tool collision with the material during deep milling, facilitates free chip removal, and reduces friction, protecting the workpiece from overheating.
• Finishing geometry: Precisely ground cutting edges enable excellent surface quality without the need for additional finishing machining.
• Three-flute design Z3: Three cutting edges allow for increased feed speed while maintaining smooth operation, excellent finishing quality and high tool rigidity.
• Positive geometry: Right-hand spiral lifts the chips upwards, protecting the lower edge of the material from scratching.
• Polished chip grooves: The mirror-like surface of the spiral reduces friction and prevents chip adherence to the tool body.
• Premium solid carbide: The rigid and wear-resistant structure of the solid carbide guarantees long tool life and maintenance of tight dimensional tolerances.
• Optimised grip roughness: Low grip surface roughness (Ra ≤ 0.3 µm) prevents slipping in the holder and protects the spindle taper.
• Dynamic balancing class G2.5: Static-dynamic balancing compliant with ISO/EN standards (class G2.5) ensures vibration-free operation at very high speeds.

Applications and material purposes:

The tool is designed for finishing operations on 3D models, deep cutting, and trimming on CNC machining centres.

Machined materials: Aluminium and composites such as CORIAN and HPL.
