Crowne Tools Big Boy 2.0 Chamfer Cone: Less is More... New Design, Same Great Results

The Crowne Tools Big Boy 2.0 Chamfer Cone is a professional diamond grinding accessory designed to simplify hole enlargement, edge refinement, bevel creation, and precision shaping on tile and stone surfaces.

Building on the success of the original Big Boy, the new 2.0 version features an innovative hollow-core construction that reduces overall weight by approximately 30%. This lighter design improves maneuverability, reduces user fatigue, and provides greater control during detailed grinding and finishing applications.

With a versatile working range of 35mm to 75mm, the Big Boy 2.0 allows installers to quickly enlarge existing openings, refine rough-cut holes, create smooth chamfers, and shape curved profiles without the vibration, chatter, or edge blowout often associated with traditional grinding methods.

The premium 70/80 grit diamond coating provides aggressive yet controlled material removal, making it suitable for both rough shaping and finish preparation. Whether working with porcelain tile, ceramic tile, granite, marble, quartz, or engineered stone, the Big Boy delivers consistent results and professional-quality finishes.

Its standard 5/8"-11 thread connection allows direct attachment to most angle grinders, making it a versatile addition to the toolkit of tile installers, stone fabricators, plumbers, electricians, and remodeling professionals.

For anyone who regularly modifies tile or stone openings, the Big Boy 2.0 provides a faster, cleaner, and more controlled solution.
