5D Carbide twist drill bits for aluminium
Introduction:
5D Carbide Twist Drill Bits for Aluminum are precision-engineered
cutting tools designed for deep-hole drilling (5× diameter) in
aluminum and non-ferrous alloys. Featuring high-performance
micro-grain carbide and optimized helix geometry, these drills
deliver superior chip evacuation, reduced built-up edge (BUE), and
extended tool life in high-speed machining applications.
Features:
1.5D Depth Ratio – Stable drilling up to 5× drill diameter
2.Aluminum-Specific Geometry – High helix angle (35°–45°) for smooth chip flow
3. Polished Flutes – Minimize material adhesion (BUE)
