Introduction:
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 the most 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.
Features:
4-flute geometry optimized for 17-4PH's work-hardening characteristics
30° spiral flute for smooth chip evacuation in deep-hole applications
Step design combines drilling and reaming functions (2D/3D drawings available)
Micro-grain tungsten carbide substrate (0.6μm) for maximum toughness
AlTiN nano-composite coating with 3,500HV hardness and 900°C oxidation resistance
Through-tool coolant capability (MQL/flood compatible)
✓ 3× longer tool life vs standard carbide reamers in 17-4PH
✓ IT6 tolerance achievable in production environments
✓ 40% higher feed rates through optimized chip breaker geometry
✓ Eliminates secondary operations with precision step machining
Diameter ranges: 3-25mm (custom sizes available)
Step configurations: 2-3 steps per tool (custom designs)
Shank types: Straight, Weldon, HSK, CAT
Special geometries: Left-hand spiral, reduced neck options
