Spiral router bit Finishing VHM Z3 D10 I25 L70 S10 RH positive TiSiN

Three-flute VHM spiral end mill with chip breaker and TiSiN coating 10x25 mm from the SC23 series – maximum lifespan and machining efficiency 

Index: SC23.10.025.070.10TR

High-performance spiral end mill made from solid sintered carbide (VHM) from the SC23 line, designed for formatting, cutting and roughing-finish operations on overhead spindle milling machines and CNC centres. The tool utilises a three-flute spiral geometry in a Z3R positive configuration, which guarantees immediate removal of dust and chips upwards while maintaining perfect cleanliness of the bottom 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 detail quality.

Construction 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) exhibits resistance to thermal loads, reduces resistance, and significantly extends tool durability.
• Z3R chip breaker geometry (upward chip ejection): The arrangement of three cutting edges with a chip breaker lowers work resistance, improves the ejection of fragmented material, and enables fast feed with ideal finishing of the bottom edge.
• Premium sintered carbide monolith (VHM): Rigid monolithic construction limits tool deflection under load and ensures high dimensional precision.
• Low roughness of the shank: Shank surface with a roughness index of Ra ≤ 0.3 µm secures the mill from rotating in the holder and eliminates the risk of wear on the spindle taper.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) minimizes noise and reduces vibrations generated at the highest speeds.

Intended use and scope of application:

The tool is intended for cutting, contour milling, slotting and medium roughing and finishing machining.

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