Precision Carbide Tipped Standard & Special Form Porting Tools for Hydraulic and Aerospace Applications
Standard & Custom Options
Carbide Tipped Port Contour Cutter Series
Engineered for maximum reliability and exact surface finishes, Rock River Tool port contour cutters produce complex form cavities in a single plunge. Choose from our standard SAE or military spec lines, or request customized profiles designed specifically for your alloy workpiece material.
S.A.E. Ports MS16142 • J514F • J1926
Precision carbide tipped port cutters designed to generate standard straight-thread O-ring fluid ports quickly with optimal chip load and fine seal surface finish.
Standard & Metric Sizes MS33649 Integral Reamer Pilot Series
Heavy-duty straight shank carbide tipped cutters featuring an integral reaming pilot to guarantee concentricity and smooth finishing on critical aerospace/hydraulic ports.
Integral Pilot Design Technical Performance
Single-Pass Accuracy for Fluid Power & Hydraulics
Machine hydraulic valve blocks, manifolds, and aerospace fluid controls with total dimensional confidence. Carbide tipped port contour cutters combine the vibration-dampening strength of a toughened steel shank with wear-resistant C2 or C5/C6 carbide inserts ground to precision profile tolerances.
- Complete Form machining: Cuts the spotface, seal angle, thread ream diameter, and pilot hole in a single spindle stroke.
- Superior Surface Finish: Micro-ground cutting edges prevent chatter marks on critical sealing faces to avoid fluid leaks.
- Rigid Steel Body: Brazed construction offers exceptional shock tolerance under interrupted entry and deep cavity operations.
- Coatings & Modifications: Available with TiAlN, AlTiN, or custom edge preparations for stainless steel, cast iron, and titanium.
