Alpha line of carbide brad point drill bits with advanced Diamond coating is specifically designed for high-precision drilling in CFRP and GFRP composites. Engineered to reduce delamination, entry tear-out, and exit chipping, these tools ensure clean, accurate holes in demanding fiber-reinforced materials.
Product Features:
• Centering Tip Design
The sharp centering tip ensures precise hole positioning, eliminating drill bit walking and slipping—essential when using tools such as a 6mm brad point drill bit or a 1/2 brad point drill bit for thin laminates.
• Anti-Delamination Geometry
Optimized cutting angles minimize layer separation and fiber tearing during drilling, whether using a 3/8 brad point drill bit for composite panels or an 8mm brad point drill bit in structural components.
• Diamond Coating Durability
The diamond coated layer delivers exceptional wear resistance, especially on abrasive fibers—extending the tool life of each carbide brad point drill bit, including common sizes like the 10mm brad point drill bit and 12mm brad point drill bit.
• Sharp Cutting Edges
Precision-ground cutting edges provide clean fiber separation, reducing burrs and delamination risk for both small sizes like the 1/4 brad point drill bit and larger diameter tools.
• Exit Chip Control
Special edge designs prevent exit blowout, ensuring high-quality hole walls across a range of composite materials and thicknesses.
• High-Strength Carbide Substrate
The robust carbide body offers superior cutting stability and precise alignment in every drilling operation.
Specifications:
7 standard specifications due to diameters and cutting depths, available in sizes like 1/4", 3/8", 1/2", 6-12mm for versatile machining, both metric and inch products available.
Applications:
Alpha’s carbide brad point drill bits with advanced diamond coating are engineered for high-precision drilling in composite materials, offering excellent performance in CNC machining and robotic automation for consistently high-quality hole processing.
• Fastener Hole Drilling
Designed for precise drilling of fastener connection holes in aircraft structures and automotive body components. Whether using a 6mm brad point drill bit for smaller fittings or a 12mm brad point drill bit for larger assemblies, clean and accurate results are ensured.
• Assembly Pre-Drilled Holes
Ideal for drilling pilot and through-holes in composite parts before assembly. Tools such as the 10mm brad point drill bit and 1/4 brad point drill bit deliver stable performance with minimal delamination.
• Tubing Installation Holes
Perfect for high-precision drilling in aerospace hydraulic systems and automotive wire harness routing. A 3/8 brad point drill bit is often used for these mid-range diameters, providing excellent centering and finish.
• Sensor and Instrument Mounting
Accurate drilling in composite housings for sensor and instrumentation mounting is critical. The 1/2 brad point drill bit and 8mm brad point drill bit are commonly selected for consistent hole dimensions and clean entry/exit profiles.
• Ventilation and Heat Dissipation Holes
Used for batch drilling of vent and cooling holes in electronic casings and radiators. The sharp geometry of carbide brad point drill bits ensures precise results even in high-volume production.
• Inspection and Maintenance Access Holes
Supports accurate drilling of access ports and service holes across a range of maintenance applications, with reliable performance from both small (e.g., 1/4 brad point drill bit) and large diameters (e.g., 12mm brad point drill bit).
