Description

The ToolDocker WT-JGS Half Round Diamond Router Bit (No. 40) is an extra-deep vacuum-brazed edge profiling tool engineered for cutting heavy full half-round (full bullnose) profiles on $3.5\text{cm}$ to $4\text{cm}$ slabs and laminated edges of engineered quartz, granite, marble, sintered stone, and porcelain. Designed with an expanded $42\text{ mm}$ top guide flange, a $12.5\text{ mm}$ center waist, and a $46\text{ mm}$ total diamond head height, it produces symmetrical, chip-free rounded borders on heavy commercial countertops, stair nosings, and pool copings with minimal post-profiling hand polishing.

Key Features

Large Full Bullnose / Half-Round Profile: Designed specifically for shaping heavy convex rounded borders on thick $3.5\text{cm}$ to $4\text{cm}$ stone slabs and laminated edge build-ups.
Expanded $42\text{ mm}$ Top Guide Disc: Stabilizes cutting along the top slab surface to control profile depth and prevent accidental gouging.
Vacuum-Brazed Diamond Layer: Industrial diamond particles fused to hardened tool steel provide fast stock removal and chip-free edge transitions on dense stone.
Heavy-Duty $1/2\text{''}$ ( $12.7\text{ mm}$ ) Shank: Eliminates chatter, tool deflection, and vibration under heavy feed pressure on CNC and portable routers.
Mandatory Wet Operation: Use with continuous flood coolant or active water mist to flush stone slurry and prevent overheating.
