Spiral end mill HSS two-flute 8x42 from the series SB01 – perfect edge quality and high machining efficiency

Index: SB01.08.042.090.08L

High-performance spiral end mill made from solid sintered carbide (HSS) from the SB01 line, designed for tasks related to precise cutting, shaping, and finishing on high-speed mills and CNC machining centres. The tool uses a two-flute spiral geometry in a positive 2 configuration, which forces efficient chip removal upwards. The use of high-quality micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's lifespan. The ground shank with a tolerance class of H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent standard of finish on the machined material.

Design advantages and technical properties:

• Finishing geometry Z2 (upward chip removal): Two cutting edges guarantee high cutting efficiency, ideal edge finishing quality, and efficient upward chip removal.
• Premium sintered carbide monolith (HSS): Rigid, monolithic construction prevents deformation of the mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• PVD coating application possibility: The option of applying protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extensions of edge lifespan, reduces friction, and protects against overheating.
• Low roughness of the shank: The surface of the shank with a roughness index of Ra ≤ 0.3 µm prevents the mill from rotating in the chuck and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to standard G2.5: Certified static-dynamic balancing in the high class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds (up to 18,000 RPM).

Application and scope of use:

The tool is designed for cutting operations, contour milling, and edge finishing.

It performs excellently in the machining of materials such as: soft and hardwood, raw MDF board, plywood, and raw chipboard.
