Description

The ToolDocker WT-JGS Diamond Emery Pattern Bit (Pattern 4) is a wide-profile vacuum-brazed edge shaping tool engineered for creating bold French cove, fillet step, and classical drop contours on engineered quartz, granite, marble, sintered stone, and porcelain slabs. With its substantial 50 mm base diameter, 26 mm total working height, top guide ball bearing, and integrated slurry discharge flutes, it provides fast, chatter-free stock removal and a clean profile finish that minimizes hand-polishing time.

Key Features

  • Wide 50 mm French Cove & Fillet Step Contour: Creates a grand, broad-sweeping architectural ogee profile for high-end countertop nosings, table borders, and fireplace mantels.

  • Dual-Tier Step Geometry (H1: 10 mm / H2: 26 mm): Allows stepped depth profiling on 2 cm and 3 cm slabs with distinct fillet and cove transition lines.

  • Sealed Top Guide Ball Bearing: Rolls smoothly against template edges or raw slab faces for clean, steady guidance with portable routers.

  • Curved Water & Slurry Discharge Channels: Integrated relief slits flush heavy stone sludge continuously to eliminate diamond glazing and thermal shock.

  • Rigid 1/2 inch (12.7 mm) Shank: Solid tool-steel body prevents chatter and tool deflection during heavy stock removal.
