Product Overview
The Kyocera 2KMBL0030-0150-S4 is a premium-grade solid carbide long neck ball nose endmill engineered for demanding CNC machining environments. Featuring the PR1535 grade substrate with advanced PVD coating technology, this tool delivers exceptional wear resistance, thermal stability, and cutting-edge integrity. The 2-flute design with long neck geometry enables machining in deep cavities and narrow ribs where standard endmills cannot reach.
Designed for deep pocket 3d contouring, the 2KMBL0030-0150-S4 is the preferred choice for precision manufacturing in mold & die, aerospace, medical, and general engineering sectors where dimensional accuracy and process reliability in deep cavities are paramount.

Operating Guidelines
- Coolant: High-pressure internal coolant (70+ bar) is strongly recommended for chip evacuation and thermal management in deep cavities. For finishing operations, minimum quantity lubrication (MQL) may be used.
- Runout: Maintain tool runout below 0.003 mm at the cutting edge. Excessive runout is critical for micro-tools and accelerates uneven wear significantly.
- Entry Strategy: Use helical or ramp entry at 1-2° angle. Avoid direct plunge into solid material. Pre-drill entry holes when necessary.
- Chip Evacuation: Ensure adequate chip evacuation to prevent recutting in deep cavities. Compressed air blast or through-spindle coolant is essential.
- Tool Life Monitoring: Monitor flank wear (VB). Replace tool when VB exceeds 0.03 mm for finishing or 0.05 mm for semi-finishing operations.
- Speed & Feed: Start at the lower end of the recommended Vc range and increase gradually. High spindle speeds (20,000+ rpm) are typical for micro ball nose endmills.
- Vibration: Use shortest possible overhang and rigid toolholder setup. Long neck tools are susceptible to chatter; reduce ae if vibration occurs.
- Step-Over: For mirror finishes, use step-over of 2-4% of ball diameter. For roughing 3D surfaces, step-over up to 10% is acceptable.
