WT-JGS Half Round Diamond Router Bit 37 (37 mm Cut Height) – Vacuum Brazed Full Bullnose Stone Edge Profiling Bit (1/2” Shank)

The ToolDocker WT-JGS Half Round Diamond Router Bit (No. 37) is an extra-deep vacuum-brazed edge profiling tool engineered for cutting large-scale full half-round (full bullnose) profiles on extra-thick 3.5 cm to 4 cm slabs and laminated edges of engineered quartz, granite, marble, sintered stone, and porcelain. Designed with a wide 40 mm top guide flange, a tight 11.5 mm waist, and a 37 mm usable cutting height, it shapes symmetrical rounded borders on heavy commercial countertops, stair nosings, and pool copings with minimal secondary hand polishing.

Key Features

• Heavy 37 mm Full Bullnose Profile: Specifically engineered for full half-round edge shaping on heavy 3.5 cm – 4 cm (up to 40 mm) laminated countertops, steps, and pool coping.

• Integrated Guide Flanges: Features a wide 40 mm top disc that rides along the slab surface to control profiling depth and prevent gouging.

• Vacuum-Brazed Diamond Layer: Industrial diamond particles fused to hardened tool steel provide rapid stock removal and clean, chip-free transitions on dense stone.

• Heavy-Duty 1/2” (12.7 mm) Shank: High-strength steel core resists tool deflection, chatter, and vibration under heavy feed pressure.

• Mandatory Wet Operation: Use with continuous flood coolant or active water mist to flush stone slurry and prevent overheating.
