Spiral router bit Roughing VHM Z3 D16 I55 L110 S16 RH positive TiSiN

VHM three-flute spiral end mill with chip breaker and TiSiN coating 16x55 mm from the SC23 series – maximum lifespan and machining efficiency 

Index: SC23.16.055.110.16TR

High-performance spiral end mill made from solid sintered carbide (VHM) from the SC23 line, designed for shaping, cutting, and roughing-finishing operations on overhead spindle milling machines and CNC centres. The tool features a three-flute spiral geometry in a Z3R configuration with a positive layout, guaranteeing immediate removal of dust and chips upwards and maintaining perfect cleanliness of the lower edge. The applied TiSiN protective coating significantly reduces friction, prevents overheating of the cutting edges, and greatly extends the tool's lifespan. The ground shank with tolerance class H6 eliminates radial runout, protecting the spindle bearing system and ensuring impeccable quality of the detail.

Design advantages and technical properties:

• Advanced TiSiN protective coating: PVD layer with microstructural hardness of 3570 HV 0.05, thickness of 1–4 µm, and low friction coefficient (0.5) demonstrates resistance to thermal loads, reduces drag, and significantly extends tool life.
• Chip breaker geometry Z3R (upward ejection): The arrangement of three cutting edges with chip breaker reduces working resistance, facilitates ejection of fragmented material, and allows for fast feed with ideal finishing of the lower edge.
• Premium sintered carbide monolith (VHM): Rigid monolithic design limits tool deflection under load and ensures high dimensional accuracy.
• Low roughness of the gripping part: The shank surface with a roughness index Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at the highest speeds.

Intended use and application range:

The tool is intended for cutting, contour milling, mortising, as well as medium roughing and finishing operations.

It performs excellently in the machining of materials such as: soft and hard wood, raw MDF board, plywood, and raw particle board.
