Description

The ToolDocker WT-JGS Half Round Diamond Router Bit (No. 18) is an industrial vacuum-brazed edge shaping tool designed for milling full half-round (full bullnose) profiles on 20 mm (2 cm) slabs of engineered quartz, granite, marble, sintered stone, and porcelain. Designed with top and bottom shoulder flanges to stabilize edge tracking, it shapes smooth, symmetrical rounded borders on countertops, stair nosings, and vanity edges with minimal secondary hand polishing.

Key Features

Full Half-Round / Bullnose Profile: Shapes a full convex semicircular edge on $20\text{ mm}$ ( $2\text{cm}$ ) stone slabs in a single operation.
Integrated Top & Bottom Guide Flanges: Features a $25.5\text{ mm}$ upper disc that rides along the top face to maintain consistent depth and prevent over-cutting.
Vacuum-Brazed Diamond Bond: High-concentration coarse industrial diamond matrix delivers rapid stock removal with minimal chipping.
Heavy-Duty $1/2\text{''}$ ( $12.7\text{ mm}$ ) Shank: Delivers rigid, vibration-free stability on CNC routers and portable stone profiling machines.
Mandatory Wet Operation: Use with flood coolant or active water mist to prevent diamond glazing and thermal stress.
