VHM Spiral End Mill Two-Edge 12.7x38.1 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.13.381.889.13R

High-performance spiral end mill made from a solid sintered carbide (VHM) monolith from the SB01 line, intended for tasks related to precise cutting, shaping, and finishing on overhead spindle milling machines and CNC centres. The tool uses a two-edge spiral geometry in a 2 configuration with a positive arrangement, which forces effective chip removal upwards. The use of high-quality micrograin carbide ensures high resistance to abrasive wear and significantly extends the longevity of the cutting edge. The ground shank with a tolerance class of H6 eliminates radial runout, protecting the bearing arrangement of the spindle and guaranteeing an excellent finish standard for the machined material.

Structural advantages and technical properties:

• Finishing geometry Z2 (upward chip removal): Two cutting edges ensure high cutting efficiency, ideal edge finishing quality, and efficient upward chip removal.
• Premium Sintered Carbide Monolith (VHM): The rigid, monolithic structure prevents deformation of the mill during work under high force, allowing for narrow dimensional tolerances.
• Option for PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the shank: The surface of the shank with a roughness indicator of Ra ≤ 0.3 µm protects the mill from twisting in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing in G2.5 norm: Certified static-dynamic balancing in a precision class of G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Purpose and scope of application:

The tool is intended for cutting operations, peripheral milling, and finishing edge machining.

It is ideal for machining materials such as: soft and hard wood, raw MDF board, plywood, and raw particle board.
