2-Flute PCD Step Reamer Head with Entrance Chamfer
Overview
The 2-Flute PCD Step Reamer Head with Entrance Chamfer is a modular reaming solution designed for high-precision finishing of multi-diameter bores with an integrated entrance chamfer. The step reaming and chamfering functions are combined in a single tool to support reduced cycle time and stable dimensional control in CNC machining of non-ferrous materials.
Supplied as a head-only modular design without an integrated shank, the reamer head allows cost-effective replacement while maintaining consistent machining performance. Equipped with polycrystalline diamond (PCD) cutting edges, the tool supports extended tool life, stable cutting behavior, and high surface quality when machining aluminum alloys, engineered plastics, and composite materials under optimized process conditions.
Product Code: PCD-SRH-2F-ST2-CH45-V1
Applications
- Precision reaming of multi-step bores with integrated entrance chamfer
- Automotive engine and transmission components requiring high-accuracy hole finishing
- Aerospace structural parts and hydraulic manifolds with multi-diameter bores
- High-volume machining of aluminum alloys, composite materials, and engineered plastics
- Modular reaming systems for CNC mass production with reduced tool change time
Key Features
- 2-flute PCD cutting edges – Balanced cutting geometry supporting stable chip evacuation and high reaming accuracy
- Step geometry per customer drawing – Supports 2-step, 3-step, or 4-step bore profiles
- Integrated entrance chamfer – Standard 45°, with optional 60°, 90°, or custom angles
- Head-only modular design – Replaceable reamer head supporting reduced tooling cost
- High concentricity – Supports precise alignment of bore steps and entrance chamfer in a single machining pass
Benefits
- Combines step reaming and entrance chamfering into one operation, supporting reduced machining time
- Supports extended tool life in non-ferrous machining compared with carbide step reamers
- Modular tool concept allows head-only replacement while retaining the shank system
- Improves bore quality in terms of dimensional consistency and surface stability
- Enhances process reliability in high-volume CNC production environments
