FULL PRODUCT DESCRIPTION
The V-30 Full Bullnose Diamond Router Bit – Position 1 is a sintered metal-bond, continuous rim diamond router bit designed for heavy shaping and initial profiling on quartz, granite, and quartzite.
What “V-30” Means
• V = Full bullnose profile
• 30 = 30 mm profile height
• 30 mm equals approximately 1.25 inches
This establishes the correct radius for a full bullnose edge used on countertops, islands, vanities, and waterfall edges.
What “Position 1” Means
Position 1 is the coarse shaping stage, using approximately 30/40 grit diamonds.
This step:
• Removes stock quickly
• Establishes the bullnose radius
• Prepares the edge for finer steps and polishing
The sintered metal bond contains high diamond concentration, exposing new diamonds as it wears for maximum cutting life and consistent shaping — especially on quartzite.
The continuous rim design produces smoother contact, cleaner shaping, and reduced chipping during heavy stock removal.
BOLT / THREAD SYSTEM (IMPORTANT)
Stone router bits do not use a half-inch arbor.
✔ True arbor shaft: 10 mm
Each bit includes two bolts, both with 10 mm shafts, but with different thread sizes:
• 10 mm shaft with 10 mm thread
• 10 mm shaft with 8 mm thread
This fits nearly all portable stone routers on the market.
Both bolts are included with every router bit.
OTHER PROFILES AVAILABLE
We sell a full lineup of profiling shapes, including:
• F-Shape (Ogee)
• E-Shape (Bevel)
• L-Shape (Cove)
• H-Shape (Dupont edge)
Each listing will include proper mm-to-inches conversion and position details.
