Application Overview

Engineered specifically for brazed carbide turning tools and tungsten carbide-tipped (TCT) saw blades. The Green Silicon Carbide wheel handles the steel blade body and back relief, while the resin-bonded diamond wheel finishes the tungsten carbide cutting edge.

Step 1: Grind the Steel Body / Tooth Back (Green SiC Wheel)

First, grind the steel shank or tooth back using the Green SiC wheel. Create a relief angle 2°–5° larger than the carbide tip (typically 25°–30° for the steel body versus 20° for the carbide). Lightly grind dry or with minimal cooling, removing approximately 0.5–1.0 mm of material.

Step 2: Rough Grinding the Carbide Cutting Edge (Diamond Wheel)

Switch to the resin-bonded diamond wheel. Apply light pressure and feed along the original rake/clearance angle. Limit depth of cut to ≤0.02–0.05 mm per pass. Always perform down-grinding (feed toward the tool root) to minimize chipping. Remove worn layers and minor chips. Use water-soluble cutting fluid coolant (3–5 L/min) to prevent thermal cracking.

Wheel Dressing & Maintenance

Regularly dress the diamond wheel using the included diamond dressing pen. This exposes fresh abrasive grains, keeps the profile flat, and prevents wheel glazing or loading (clogging).
