BEYOND HRC60 5D Carbide Drill Bits - 120mm Total Length for Extreme Deep Hole Drilling Applications
Experience unprecedented deep hole drilling capability with the BEYOND 5D series featuring a massive 120mm total length. Engineered with an advanced 140° point angle and exceptional 5x diameter flute length, these extreme-length HRC60 carbide drills conquer the most challenging deep cavity operations. Designed for applications where conventional drills simply cannot reach, providing ultimate solutions for deep mold manufacturing, long structural components, and complex industrial applications.
Key Features & Benefits:
- Extreme 120mm Total Length: Unprecedented reach capability enables drilling in deep cavities and hard-to-reach areas that standard drills cannot access, eliminating the need for specialized extension tools.
- Maximum 5xD Flute Length: Superior 5:1 depth-to-diameter ratio provides exceptional drilling depth while maintaining precision and stability throughout the entire length.
- Optimized 140° Point Angle: Advanced point geometry reduces thrust force by 60-75%, ensures perfect centering accuracy, and prevents walking on complex surfaces.
- HRC60 Ultra-Hard Tungsten Carbide: Maximum wear resistance and structural integrity maintain dimensional stability through extended deep-hole operations in abrasive materials.
- Reinforced Core Construction: Enhanced web thickness and optimized flute geometry deliver maximum torsional strength, minimizing deflection and breakage risk in extreme-length applications.
- Precision Straightness Guarantee: Each drill undergoes rigorous straightness testing to ensure perfect alignment throughout the 120mm length, guaranteeing accurate hole geometry.

Technical Application Guidelines:
Special considerations for 120mm length drilling operations:
| Diameter Range | Recommended Speed Reduction | Feed Rate Adjustment | Critical Application Notes |
|---|---|---|---|
| 1-6mm | Reduce 40-50% vs standard | Reduce 30-40% | Frequent pecking required, high-pressure coolant essential |
| 7-12mm | Reduce 30-40% vs standard | Reduce 20-30% | Aggressive chip evacuation, rigid setup critical |
| 13-20mm | Reduce 20-30% vs standard | Reduce 15-25% | Maximum machine rigidity required, hydraulic chucks recommended |
Extreme Length Drilling Protocol: Use specialized peck drilling cycles with frequent retractions (every 0.5-1xD). Maintain ultra-high-pressure coolant flow (minimum 40 bar) through the tool. Implement reduced ramp-in feed rates. Ensure absolute machine rigidity and use precision hydraulic or shrink-fit chucks. Conduct regular tool inspection for wear and straightness.
