PCD Combination Tool for Stepped Bore & Counterboring
Overview
The PCD Combination Tool for Stepped Bore & Counterboring is engineered to consolidate multiple machining steps into a single, efficient process. By integrating drilling, counterboring, and precision reaming within one custom-designed tool, manufacturers benefit from superior accuracy, reduced cycle times, and lower overall tooling costs.
Equipped with polycrystalline diamond (PCD) cutting edges, this tool delivers outstanding wear resistance, process stability, and long service life when machining aluminum alloys, composites, and non-ferrous metals. Each tool is tailored to customer-specific bore profiles, ensuring consistent geometry, tight tolerances, and exceptional surface finishes.
Applications
Automotive components such as cylinder heads, valve bodies, and transmission housings
Aerospace structures requiring stepped bore and counterbore precision finishing
Hydraulic and pneumatic systems with multi-diameter bore requirements
Precision engineering sectors machining aluminum, copper, magnesium, and advanced composites
