Product Overview
The Kyocera SGM00542 is a premium ENDMILL 4FL SQ solid carbide endmill engineered for high-performance machining. Featuring a 0.033" cutting diameter and Square End configuration with 4 flutes, this tool delivers exceptional surface finish, dimensional accuracy, and extended tool life in demanding production environments. The 4-flute design provides higher feed rates and superior core strength compared to 2-flute alternatives, making it ideal for finishing and high-speed side milling operations. Manufactured from Micro-Grain carbide substrate with advanced coating technology, it is the preferred choice for applications requiring tight tolerances and superior chip control.

| Radial Depth (ae) | 0.2-0.6xD | 0.3-0.8xD |
Operating Guidelines
- Rigidity: Ensure minimum tool overhang and rigid workholding to prevent vibration and chatter
- Coolant: Use high-pressure coolant (70+ bar) for steel; compressed air or mist for aluminum to prevent thermal shock
- Runout: Maintain TIR below 0.005 mm for optimal tool life and surface finish
- Ramping: Use helical ramp entry at 2-3° angle for pocketing operations; avoid direct plunge
- Speed/Feed: Start at lower end of recommended range and increase gradually based on chip formation and sound
- Tool Life: Monitor flank wear; regrind or replace when wear land reaches 0.2 mm
- Chip Load: Maintain consistent chip thickness to avoid rubbing and premature wear
- Storage: Store in original packaging away from moisture and corrosive environments
Toolholder Compatibility
| Holder Type | Compatible Size | Recommended Torque |
