PCD Combination Tool – Precision Stepped Bore & Counterboring
Overview
The PCD Combination Tool for Stepped Bore & Counterboring is designed to streamline complex machining operations by integrating multiple steps into a single precision tool. Built with polycrystalline diamond (PCD) cutting edges, it ensures outstanding wear resistance, extended tool life, and micron-level dimensional accuracy.
Engineered for automotive, aerospace, and high-volume CNC production, this tool significantly reduces cycle time and tool changes while maintaining strict bore tolerances and consistent surface finishes. Custom geometries—including step diameters, chamfer angles, and counterbore profiles—are available to match customer-specific drawings and applications.
Applications
Stepped bore finishing in automotive and aerospace parts
Counterboring operations requiring precision and stability
Hydraulic and pneumatic components with multi-feature bores
High-volume machining of aluminum alloys, magnesium, and composites
Precision housings and die-cast parts with combined bore and counterbore features
PCD REAMER:
SOLID CARBIDE REAMERS :
BRAZED CARBIDE REAMERS :
Key Features
Multi-function tool – Combines stepped bore reaming and counterboring in one pass
