5D Carbide Twist Drill Bits Customized Drill Bits For Aluminium

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)
