Our 4-flute coolant-through step reamer is specially engineered for precision hole machining in 17-4PH precipitation-hardening stainless steel and other tough materials. Featuring advanced AlTiN coating and internal coolant channels, this carbide reamer delivers exceptional tool life and dimensional accuracy in demanding machining conditions.
The unique step design allows for combined drilling and reaming operations in a single tool, significantly reducing cycle times while maintaining tight tolerances (IT6-IT7). Ideal for aerospace, medical, and oil/gas applications where 17-4PH stainless steel's combination of high strength and corrosion resistance challenges conventional cutting tools.
- Superior Tool Design: 4-flute geometry optimized for 17-4PH's work-hardening characteristics, 30° spiral flute for smooth chip evacuation, step design combines drilling and reaming functions
- Advanced Material Technology: Micro-grain tungsten carbide substrate (0.6μm), AlTiN nano-composite coating with 3,500HV hardness, through-tool coolant capability
- Performance Advantages: 3× longer tool life vs standard carbide reamers, IT6 tolerance achievable, 40% higher feed rates, eliminates secondary operations
- Customization Options: Diameter ranges 3-25mm, step configurations 2-3 steps per tool, various shank types, special geometries available
- Aerospace Components: Landing gear pivot holes, engine mount bushings
- Medical Implants: Orthopedic device through-holes, surgical instrument precision bores
- Oil & Gas Equipment: Valve body seat machining, downhole tool flow channels
- General Precision Engineering: Hydraulic manifold systems, bearing housing bores
