Diamond core drill bit GEKO 102x10x450 mm 9T 1¼" for dry and wet drilling

Diamond core drill bit GEKO 102x10x450 mm 9T 1¼" for dry and wet drilling is a cylindrical cutting tool designed to create precise round holes in masonry, concrete, natural stone and ceramic tile. With a 102 mm cutting diameter, 10 mm diamond segment height and 450 mm total length, this core bit is compatible with hand-held core drills and drill rigs that accept a 1¼" thread connection. It is intended for both wet and dry drilling methods, providing efficient material removal and clean hole walls when used under appropriate conditions.

Advantages

The GEKO diamond core bit combines a robust diamond segment configuration (9T pattern) with a durable steel body to balance cutting speed and wear resistance. Its 10 mm segment height offers extended life on demanding materials, while the 1¼" threaded connection ensures straightforward mounting on common drilling equipment. The ability to use the bit in wet or dry modes allows adaptation to site conditions and specific task requirements.

Suitable for

• Making circular openings for plumbing pipes and conduits
• Creating holes for electrical installations and cable entries
• Drilling clean holes for HVAC and ventilation ducts
• Cutting openings for anchor bolts and fixing systems

How to use

Mount the GEKO diamond core bit securely on a drill with a 1¼" spindle or appropriate adapter. For wet drilling, supply a steady water flow to the cutting area to cool the segment and remove slurry; for dry drilling, ensure intermittent drilling and adequate dust extraction to prevent overheating and prolong segment life. Use steady axial pressure without forcing the bit; allow the diamonds to abrade the material at their natural cutting rate. When drilling deep holes, periodically withdraw the bit to clear debris and check alignment.

Usage recommendations

Use appropriate personal protective equipment (eye protection, dust mask or respirator, hearing protection and gloves). Match drill speed and feed rate to the material: slower speeds for harder stones and consistent water feed for wet cutting. Avoid excessive lateral force or hammering action. Store the bit dry and inspect segments regularly for wear; replace when segment height is insufficient for safe operation.
