BEYOND HRC60 5D Carbide Drill Bits (15-20mm) - Maximum Performance for Heavy Industrial Deep Hole Drilling
Conquer the most extreme deep hole drilling challenges with the BEYOND 15-20mm 5D series. Engineered with an advanced 140° point angle and exceptional 5x diameter flute length, these heavy-duty HRC60 carbide drills deliver uncompromising performance in the most demanding deep cavity operations. Designed for maximum productivity in heavy machinery, large-scale manufacturing, and structural applications where ultimate reach and precision are critical.
Key Features & Benefits:
- Maximum 5xD Flute Length: Superior 5:1 depth-to-diameter ratio enables drilling deep cavities up to 100mm, providing exceptional reach for large industrial components and eliminating the need for specialized deep-hole drilling equipment.
- Optimized 140° Point Angle: Advanced point geometry reduces thrust force by 55-70%, ensures perfect centering accuracy, and prevents walking on uneven or hardened surfaces.
- HRC60 Ultra-Hard Tungsten Carbide: Maximum wear resistance and structural integrity maintain dimensional stability through extended deep-hole operations in the most abrasive materials.
- Heavy-Duty Core Construction: Enhanced web thickness and optimized flute geometry deliver maximum torsional strength, minimizing deflection and breakage risk in the most demanding applications.
- Industrial-Grade Flute Design: Specialized helix angle and polished flute surfaces ensure superior chip evacuation, preventing chip packing and tool failure during maximum depth drilling operations.

Heavy-Duty Deep Hole Drilling Tip: Implement aggressive peck drilling cycles (G83) with retractions every 1-1.5x diameter for optimal chip control. Maintain high-pressure coolant flow (minimum 30 bar) through the tool. Reduce feed rates by 25-35% when drilling beyond 3xD depth. Ensure maximum machine rigidity and use precision hydraulic chucks to minimize vibration and deflection.
