Multi-Stage PCD Combination Tool
Overview
The Multi-Stage PCD Combination Tool from Aoshiji® Custom Tool integrates drilling, reaming, and counterboring into a single high-performance solution. Designed for high-volume CNC production, it reduces the number of tool changes, shortens cycle times, and improves process stability. Equipped with polycrystalline diamond (PCD) cutting edges, these tools deliver exceptional wear resistance, accuracy, and surface quality—making them ideal for automotive, aerospace, and precision component manufacturing.
Applications
Automotive engine and transmission parts requiring multi-feature bores
Aerospace components with strict tolerance and surface finish requirements
Hydraulic and pneumatic system housings with complex bore geometries
Precision machining of aluminum alloys, magnesium alloys, and composites
High-volume production lines seeking cycle time reduction and process reliability
See our WCBS valve body PCD combination drill case study for actual cutting parameters and reported tool-life results in 6061 aluminum production machining.
Key Features
Multi-stage geometry – Combines drilling, reaming, and counterboring in one tool
PCD cutting edges – Superior wear resistance and extended service life
High accuracy – Maintains IT6 or tighter tolerances across multiple operations
Mirror-like finish – Achieves Ra ≤ 0.2 µm on non-ferrous materials
Custom configurations – Tailored to part drawings and customer specifications
Coolant-through design optional – Ensures efficient chip evacuation and thermal stability
Benefits
Reduces setup time by consolidating multiple machining operations
Improves machining accuracy with one-pass, multi-function tooling
Lowers tooling costs by reducing tool count and changeovers
Extends tool life with PCD cutting edges compared to carbide tools
Boosts productivity in demanding mass-production environments
