Manufacturing Expertise & Standards
Precision Engineering & Carbide Grade Optimization
Selecting the optimal cutting tool depends on workpiece hardness, machine rigidity, tool overhang, and coolant application. Rock River Tool manufactures cutting tools using micro-grain tungsten carbide tips induction-brazed to heat-treated alloy steel shanks.
- Micro-Grain Carbide Substrates: Formulated specifically for high-shock resistance on interrupted cuts and abrasive machining.
- C2 (Grade 883) Substrates: Engineered for gray iron, ductile iron, aluminum alloys, brass, bronze, plastics, and non-ferrous materials.
- C5 / C6 (Grade 370) Substrates: Formulated for carbon steels, alloy steels, tool steel, stainless steel, and tough cast metals.
- Rigid Tolerances: Standard tooling manufactured to strict diameter and TIR (Total Indicator Reading) concentricity limits.
- Special Geometry Grinding: Custom step diameters, non-standard flute lengths, alternate helix angles, corner radii, and custom shanks produced in-house.
| Material Group | Recommended Grade | Primary Cutting Advantage |
|---|---|---|
| Cast Iron & Ductile Iron | Premium C2 (Grade 883) | High wear resistance against abrasive sand & scale inclusions. |
| Aluminum, Copper & Brass | Premium C2 (Grade 883) | Prevents galling and built-up edge (BUE) on cutting lips. |
| Carbon & Alloy Steels (< 35 HRC) | Premium C5 / C6 (Grade 370) | Superior crater wear resistance under high cutting temperatures. |
| Stainless Steel & Tough Alloys | C5/C6 + Custom Coating | Reduces work-hardening; maintains sharp cutting geometry. |
| Interrupted & Scaly Cuts | Carbide Tipped (Steel Body) | Dampens chatter and shock that shatter solid carbide. |
