This Bit will not work on standard 10mm Router Shaft- only 8mm

The Venom V20 Shape Diamond Router Bit – Full Bullnose is designed for precision edge profiling on granite, quartz, quartzite, and natural stone.

The V Shape (Full Bullnose) profile creates a fully rounded edge, commonly used on countertops, islands, vanities, and table edges.

This listing includes both Position 0 (coarse shaping) and Position 1 (line refining) options, selectable from the dropdown menu.

Position Options (REAL-WORLD USE — LOCKED)

Position 0 – Aggressive Shaping (30 Grit)

• Approx. 30 grit diamond bond
• Segmented rim design
• Fast cutting and heavy stock removal
• Leaves visible grind lines
• Used for initial shaping and rough profiling

Position 1 – Line Refining / Cleanup (45 Grit)

• Approx. 45 grit diamond bond
• Continuous rim design
• Designed to refine and remove the grind lines left from Position 0
• Not a final finish — prepares the edge for polishing
• Creates a smoother, more uniform profile before pads

Mounting System (IMPORTANT)

All router bits in this listing use an 8mm bolt mounting system with an 8mm thread size.

This standardized mounting design ensures a secure fit and compatibility with router bodies designed for 8mm bolt-mounted tools.

Profile Explanation (V Shape – Full Bullnose)

The V Shape (Full Bullnose) profile creates a fully rounded edge, one of the most popular finishes in countertop fabrication for a smooth, modern look.
