Thick Compax™ PCD Drill Pin Blanks

Hyperion Materials & Technologies offers Thick Compax PCD drill pin blanks with a cemented tungsten carbide base and a thick PCD layer for consistent performance and extended tool life. Manufactured as cylindrical blanks without helical flutes, these blanks are ideal for producing drills used on aluminum, titanium, and advanced composites.

Thick Compax PCD drill pins are designed for high-speed machining and the miniaturization of abrasive non-ferrous materials, such as carbon fiber-reinforced polymer (CFRP), silicon carbide (SiC), and fiberglass in demanding aerospace, automotive, and electronics manufacturing environments. Combined with a cemented tungsten carbide base and a thick diamond layer, Thick Compax PCD drill pins deliver unmatched wear resistance, repeatable performance, excellent tool life, and long-lasting performance when machining abrasive, non-ferrous materials.
 

Unmatched Geometric Consistency

Thick compax PCD drill pin blanks maintain exceptionally tight dimensional tolerances and produce superior surface finishes in highly abrasive materials like SiC, CFRP, and advanced composites. These blanks enable toolmakers to achieve precision-engineered tooling that meets the exact specifications for electronics, aerospace, and automotive manufacturing. Toolmakers can create tooling that achieves highly accurate holes for components with extremely critical tolerances while minimizing tool breakage.

 

Reduce Tooling Costs Per Part

Thick Compax PCD drill pin blanks help manufacturers lower operating costs by delivering exceptional wear resistance and unmatched durability. Superior hardness dramatically reduces tool wear, minimizing the need for frequent replacements and cutting downtime. Consistent performance reduces scrap and rework, driving down the cost per part while extending production runs. Longer tool life means fewer interruptions, greater efficiency, and a stronger return on investment, giving manufacturers the confidence to meet demanding schedules without sacrificing quality.
 

Key Industries & Applications

 

Aerospace

Aerospace manufacturing demands precision and durability when working with advanced materials. Thick Compax PCD drill pin blanks are used for drilling fastener holes in composite-metal stacks, engine components, and structural assemblies. These blanks enable tooling that significantly reduces delamination and minimizes tool breakage, two critical concerns in high-performance aerospace applications.

By incorporating Thick Compax PCD drill pin blanks, the tooling delivers superior hole quality and maintains dimensional accuracy when drilling highly abrasive materials. This technology ensures consistent performance across demanding production environments, and for manufacturers seeking to optimize efficiency and reliability in aerospace machining, Thick Compax PCD drill pin blanks deliver a proven solution that combines strength, precision, and longevity.
 

Electronics

Precision at the micro-scale is non-negotiable in electronics manufacturing. When drilling holes for circuit boards or advanced electronic components, even the slightest tool wear can lead to dimensional inaccuracies, surface defects, and costly rework. That's why toolmakers working in this space demand solutions that deliver uncompromising accuracy and durability.
 
Thick Compax PCD drill pin blanks provide clean, accurate holes in highly abrasive non-ferrous materials, such as SiC, ceramics, gallium nitride, silicon, and advanced composites. Tooling made with these blanks reduces stress concentrations, misalignments, and tolerance issues, minimizing tool deflection and ensuring that every component meets stringent quality standards. This level of consistency is critical for electronics applications, where reliability and repeatability define success.
 
For manufacturers under pressure to deliver high-quality components at scale, Thick Compax PCD drill blanks enable shops to maintain precision across extended runs, reducing scrap and rework and keeping production flowing without costly downtime. In any application where micro-scale errors can lead to macro-scale failures, investing in superior tooling isn't just smart; it's essential.
 

Automotive 

Efficiency and precision are critical in automotive manufacturing, where high-speed drilling of lightweight materials like aluminum alloys and advanced composites is the norm. Traditional tooling solutions, such as carbide or high-speed steel drills, struggle to keep pace with these demands due to rapid wear under abrasive conditions. This can lead to shorter run times, frequent tool changes, and costly production interruptions. Every unscheduled stop adds labor, increases downtime, and disrupts workflow, ultimately impacting profitability and delivery schedules.
 
Thick Compax PCD drill pin blanks offer superior wear resistance and are engineered to maintain sharpness and dimensional accuracy, extending production cycles while ensuring flawless accuracy. Toolmakers can deliver consistent hole quality, reducing the risk of misalignment, tolerance issues, and surface defects. This reliability supports high-speed drilling without sacrificing accuracy, enabling manufacturers to meet stringent quality standards while maintaining throughput.
