Description

The ToolDocker WT-JGS Corner Round Diamond Router Bit (R8) is a professional vacuum-brazed edge shaping tool engineered for creating uniform $8\text{ mm}$ radius (approx. $5/16\text{''}$ ) roundover edge profiles on engineered quartz, granite, marble, sintered stone, and porcelain slabs. Equipped with a top guide ball bearing, wide $30.5\text{ mm}$ profile head, and a heavy-duty $1/2''$ shank, it allows portable router machines to follow slab edges cleanly without chatter, providing smooth edge transitions that significantly cut down on hand-polishing time.

Key Features

Medium R8 ( $8\text{ mm}$ ) Corner Roundover: Creates a smooth $8\text{ mm}$ ( $5/16\text{''}$ ) radius bullnose edge on countertop borders, window sills, stair treads, and vanity tops.
Top Guide Ball Bearing: Smooth-rolling sealed bearing follows the workpiece edge directly for easy template routing with handheld portable stone routers.
Fluted Slurry Evacuation Channels: Built-in clearance slits optimize water flow and clear stone slurry fast, preventing heat buildup and diamond glazing.
Vacuum-Brazed Diamond Bond: High-concentration diamond particles deliver fast material removal and chip-free edge shaping on hard stone slabs.
