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.

Specialized Extreme Length Applications:

  • Deep Mold Manufacturing: Extra-long cooling channels, deep ejector systems, and complex core ventilation in large injection molds
  • Aerospace Structural Components: Deep lightening holes, long fuel passages, and structural members in aircraft frames
  • Automotive Engineering: Long hydraulic passages in transmission cases, deep engine block channels, and chassis components
  • Industrial Machinery: Deep mounting holes in machine frames, long hydraulic manifold passages, and equipment structural members
  • Energy Sector: Deep drilling in turbine components, long generator housing passages, and energy equipment manufacturing
  • Specialized Tooling: Jig and fixture manufacturing, deep locating holes, and specialized industrial equipment
