WT-JGS Cove Box Diamond Router Bit R15 (30.8 mm Head) – Vacuum Brazed Stone Fluting & Drain Groove Bit (1/2” Shank)

The ToolDocker WT-JGS Cove Box Diamond Router Bit R15 is an industrial vacuum-brazed profiling tool designed for cutting smooth, wide 15 mm radius cove channels, countertop drainage grooves, architectural fluted columns, and concave relief profiles on engineered quartz, granite, marble, sintered stone, and porcelain slabs. With an expanded 30.8 mm dome diameter, integrated slurry discharge flutes, and a rigid 1/2” shank, it removes stock quickly with minimal chatter and leaves a smooth transition finish that reduces post-carving polishing steps.

Key Features

• Wide R15 (15 mm) Cove Radius: Calibrated for large-radius cove shaping, wide drainage channels on countertop drainboards, and deep architectural fluting.

• Internal Water/Slurry Slits: Integrated fluted cooling channels ensure continuous water access to the cutting zone, flushing abrasive stone slurry to avoid glazing.

• Aggressive Vacuum-Brazed Diamond Layer: Industrial diamond grit metallurgical-bonded directly to the core delivers high-speed material removal and chip-free profiling.

• Rigid 1/2″ (12.7 mm) Shank: Provides high structural stability and absorbs torque on CNC spindles and portable stone profiling machines.
