Product Overview
The Kyocera 0.0750 BN TA SGM04376 is a precision-engineered solid carbide endmill 3fl designed for high-performance CNC milling operations. Manufactured in Japan to exacting tolerances, this ball-nose endmill delivers exceptional surface finish, dimensional accuracy, and extended tool life across a wide spectrum of workpiece materials.
With a 0.075" cutting diameter and 3 flutes arranged at a 38° helix angle, the SGM04376 is optimized for heavy-duty roughing and semi-finishing applications. The advanced AlTiN + Si coating minimizes built-up edge and provides outstanding thermal protection, enabling dry or near-dry machining even in demanding hardened-steel applications.

Operating Guidelines
- Always use balanced, high-precision toolholders (G2.5 or better at max RPM).
- Minimize tool overhang to reduce vibration and improve surface finish.
- Use climb milling wherever possible to reduce cutting forces and extend tool life.
- Ensure workpiece is securely fixtured; micro-endmills are sensitive to vibration.
- Start with lower cutting parameters and gradually increase based on machine stability.
- Inspect tool edges before each use; even micro-chipping affects performance at small diameters.
- For hardened materials, use minimum quantity lubrication (MQL) or oil mist to prevent thermal shock.
- Verify spindle runout is less than 0.005 mm (0.0002 in) for optimal results.
Toolholder Compatibility
| Holder Type | Recommended Models | Runout Requirement |
