Single-blade spiral end mill VHM for PLEXI with upward chip removal – clean bottom edge and efficient chip evacuation

Index: ST28.03.012.060.06RE

Industrial single-blade spiral end mill made from solid sintered carbide (VHM) with positive geometry (upward chip removal). The tool is equipped with a small angle of the helical line, which effectively prevents lifting and vibrations of the processed material. It is excellent for precise cutting, joining and edging thin materials with a thickness of 1 mm to 8 mm on CNC machines and overhead spindle milling machines. The finishing geometry with a single blade (Z1) combined with a polished fluting prevents sticking and melting of the chips. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system and ensuring processing stability.

Design advantages and technical properties:

• Dedicated to thin materials (1–8 mm): Reduced spiral eliminates upward pulling forces, preventing the lifting of flimsy sheets.
• Single-blade Z1 (positive) design: The single cutting blade allows for efficient chip removal, minimizing friction and the risk of overheating the material.
• Polished fluting: The mirror-like surface of the spiral prevents chip binding and re-welding of chips with the tool body.
• Finishing blade geometry: Precisely sharpened edge ensures perfect edge quality without fraying.
• 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 in class G2.5: Balancing in accordance with ISO standards ensures vibration-free operation at very high speeds.

Intended use and application range:

The tool is designed for cutting operations as well as joining and edging in thin sheets of plastic on CNC machining centres.

Used for machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2 and composite materials like CORIAN® and HPL.
