Crown Adapters & Holders – Secure Mounting for Every Material

Adapter types by mounting system

The most common systems are M14 thread for angle grinders, SDS plus/max for rotary hammers, and hex shank for standard drills. BIHUI Diamond Crown Set for Ceramics M14 DBDMK4 comes with an M14 adapter that allows mounting on standard grinders. Your choice depends on the tools you already own and the materials you plan to work with.

Adapters for diamond crowns

Diamond crowns for ceramics, granite and concrete require stable adapters with sufficient rigidity to prevent vibrations. M14 thread is the industry standard for wet and dry drilling of hard materials. Quality adapters feature anti-dropout protection and a center pilot for precise positioning.

Holders for bi-metal hole saws

Bi-metal crowns for metal and wood use hex or SDS shanks. GRAPHITE Metal Cutting Hole Saw requires a matching adapter that transmits full torque without slipping. Pay attention to the maximum crown diameter the adapter supports – typically ranging from 16mm to 150mm.

Compatibility with tool brands

Check your tool's mounting type before purchasing. Milwaukee and Machtig use universal standards, but individual models may have specific requirements. Verify the chuck type specification in your drill or grinder manual to avoid compatibility issues.

What to check before buying

Adapter material determines durability – heat-treated steel is the minimum for professional use. Brands like Bihui, Graphite, Hogert and Topex offer a balance between price and quality. Always verify that the adapter includes a center pilot bit for precise drilling initiation on hard surfaces.
