Alpha diamond-coated composite hand drill bits adopt polycrystalline diamond coating technology, specifically designed for drilling carbon fiber (CFRP) and glass fiber (GFRP) composites. They effectively prevent delamination and burrs, significantly extend service life, and reduce replacement frequency and processing costs.

Alpha Diamond-coated universal hand drill is specifically designed for CFRP/GFRP and multi-layer metal composite structures. It can drill through heterogeneous material stacks in a single pass, avoiding positioning errors from tool changes, effectively preventing delamination and tearing, and is suitable for various on-site scenarios such as repair and assembly.

Alpha Diamond Coated Thread Shank Carbide Drill is specifically designed for ADU Automatic Drilling Units. The threaded connection prevents slipping and detachment during high-speed operations, while the carbide substrate provides exceptional rigidity, ensuring the stability and precision of continuous automated drilling.

Alpha's diamond-coated countersink drills are specially designed for countersinking composite materials. The ultra-hard diamond coating effectively resists fiber abrasion, ensures precise and consistent countersink angles, and significantly extends tool life. They are the ideal choice for precision machining of composite parts in aerospace and automotive industries.
