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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
