Diamond-Tipped Core Drill Bit KREATOR KRT100202 Ø43 mm for Stone

Diamond-Tipped Core Drill Bit KREATOR KRT100202 Ø43 mm for Stone is a cylindrical core bit designed to create clean through-holes in natural stone and other hard masonry materials. The cutting rim is impregnated with diamond grit to provide enhanced cutting performance and longer service life compared with conventional carbide bits. The bit has a 43 mm cutting diameter and a hollow core body that removes a solid plug while producing smooth, accurate holes when used with compatible rotary drills or core drill adapters.

Advantages

The diamond cutting edge delivers improved wear resistance and consistent cutting speed when working with dense, abrasive stone. The hollow core design reduces load on the drill motor and helps extract a cylindrical core. The bit is suitable for wet or dry drilling when appropriate equipment and procedures are used, and its construction minimizes chipping for neater hole edges. Standard shank compatibility allows use with common drill chucks and core adapters for professional and DIY installations.

Suitable for

• Drilling through natural stone, granite, marble and similar hard masonry
• Creating holes for plumbing pipes and electrical conduits
• Installing anchors, fasteners and through-bolts in stone surfaces
• Making precise openings for fixtures and fittings during renovation

Key specifications

• Cutting diameter: 43 mm
• Tip material: diamond-impregnated cutting edge
• Body type: hollow core (core drill)
• Compatible with: rotary drills and core drill adapters (check shank/chuck compatibility)
• Intended materials: natural stone, granite, marble and similar hard masonry

How to use

Secure the core drill bit in a compatible drill or core adapter according to the tool manufacturer’s instructions. Mark the drilling position on the stone surface and, if possible, use a center punch or guide to prevent wandering. Begin drilling at low speed to establish a pilot groove, then increase speed and apply steady, even pressure. If using wet drilling, ensure a constant water supply to cool the diamond rim and remove debris; when dry drilling, take frequent breaks to avoid overheating. Withdraw the bit periodically to clear the core and slurry. After reaching the required depth, stop the drill and extract the core plug carefully.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, dust mask, gloves) and follow the drill and accessory manufacturer’s safety guidelines. For best results on very hard stone, prefer wet drilling with adequate cooling to extend bit life; verify shank compatibility and secure workpiece to prevent movement during drilling.
