PCD drills in Sandwich type

PCD drill in Sandwich type is a specialized tool developed for hole machining of materials like aluminum alloys/CFRP. Its excellent cutting edge sharpness and chip-breaking ability effectively solve defects such as delamination, burrs, and tearing that are common when machining composite materials with traditional drills. It can produce high-quality holes with high dimensional accuracy, smooth hole walls, and smooth transitions between layers in a single operation. It is an ideal solution for efficient, high-quality drilling of stacked structures.

● Efficient Laminated Material Machining: The unique cutting edge design allows for drilling through different material layers (soft and hard) in a single pass without tool changes, offering extremely high machining efficiency.
● Excellent Hole Quality: Effectively suppresses delamination and tearing at the exit of composite materials and burrs at the entrance of aluminum alloy holes, achieving high-quality hole entrances/exits and walls.
● Ultra-Long Tool Life: The extremely wear-resistant PCD cutting edge offers a lifespan far exceeding that of carbide drills, especially when machining abrasive composite materials.

● Aerospace: Machining of connection holes in stacked materials like carbon fiber reinforced polymer (CFRP) and aluminum/titanium alloys for components in aircraft, missiles, etc.
● New Energy Vehicles: Drilling of stacked components containing aluminum alloys and composite materials in battery pack casings and body parts.
● Rail Transportation: Machining of connection holes in aluminum profiles and composite interior panels for high-speed rail and subway carriages.
