Special Tool Manufacturing to Exact Blueprints
When standard catalogue dimensions fall short of your machining requirements, Rock River Tool, Inc. delivers custom-engineered cutting tooling tailored to your part drawings. From non-standard diameters and special step geometries to custom carbide grades and internal coolant channels, our engineering group works directly with procurement teams and manufacturing engineers worldwide.
Custom Tool Engineering Capabilities
Our state-of-the-art grinding room and braze facility produce specialized tools engineered for challenging workpiece materials including hardened steels, ductile iron, high-temp aerospace alloys, and abrasive non-ferrous materials.
- Special Shank Geometries: Weldon flats, reduced shanks, Morse tapers, and custom locking grooves.
- Form & Step Combination: Step reamers, multi-diameter counterbores, dovetail cutters, and porting tools.
- Precision Grinding Tolerances: Micro-inch surface finishes, tight outer diameter tolerances, and controlled corner radii.
- Coolant Delivery Options: Coolant-through the spindle or axial/radial coolant channels for deep-hole chip evacuation.
- Application Carbide Grades: Premium C-2 (883 grade) for non-ferrous materials and C-5/C-6 (370 grade) for steel cutting.
