FANAR solid carbide end mill 8.0 mm R0.5, 19/63 Z4 HA8 VHM TS R440N MASTERMILL

FANAR solid carbide end mill 8.0 mm with a corner radius of R0.5 is a precision milling cutter designed for accurate slotting, profiling and finishing operations. Manufactured from solid carbide, the tool combines rigidity and wear resistance for consistent dimensional results when machining a range of metallic materials. The cutter has four flutes and a small-radius corner that helps produce rounded internal corners and improved surface quality in tight geometries.

Advantages

The solid carbide construction delivers high stiffness and prolonged tool life under appropriate cutting conditions. The R0.5 corner radius reduces stress concentration at internal corners and improves edge strength compared with a sharp corner. Four flutes provide a balance between chip capacity and surface finish for medium to fine finishing passes. The tool geometry and coating are optimized for stable cutting performance, repeatable tolerances and predictable tool wear.

Suitable for

• Precision slotting and pocketing in steel and non-ferrous metals
• Profiling and contour milling with small internal corner radii
• Finish passes where dimensional accuracy and surface quality are required
• High-speed or CNC milling applications demanding consistent tool life

Key specifications

• Diameter: 8.0 mm
• Corner radius: R0.5
• Number of flutes: 4
• Material: solid carbide
• Intended use: end milling for slotting, profiling and finishing

How to use

Select appropriate spindle speed and feed per tooth according to workpiece material and machine rigidity. Use coolant or mist where applicable to manage cutting temperature and evacuate chips. For slotting, program multiple shallow passes rather than a single deep cut to reduce tool deflection and prolong tool life. Verify runout and clamping rigidity before machining to ensure accurate concentricity and repeatable results.

Usage recommendations

Optimize cutting parameters for the specific alloy being machined, monitor tool wear periodically, and replace the tool when edge rounding or chipping affects part tolerances or surface finish.
