Applications

Use for holes in ceramic or porcelain tile and suitable natural stone, including granite and marble, with equipment matched to the bit. These are tile/stone drilling accessories, not a general drywall-bit recommendation.

Selection and Use

• Verify both the diameter and thread before ordering, particularly the 43 mm M14 option.
• Use a compatible high-speed grinder or a manufacturer-approved drill and adapter arrangement; an adapter is not included with an individual bit unless specifically listed.
• Do not use hammer mode. Observe the bit’s operating procedure and speed limits rather than assuming a slow drill will perform like a grinder.
