Diamond Core Drill Bit GEKO 52x10x450 mm 5T 1.1/4" for Wet and Dry Drilling

Diamond Core Drill Bit GEKO 52x10x450 mm 5T 1.1/4" for Wet and Dry Drilling is a segmented diamond core bit sized for a 52 mm bore with a 10 mm cutting depth and overall length of 450 mm. The bit features a 5-segment (5T) configuration and a standard 1.1/4" threaded connection, designed to fit compatible core drilling rigs and hand-held drill rigs. It is made for use on masonry, concrete, ceramic tiles and similar hard building materials and is suitable for both wet and dry drilling methods where a threaded 1.1/4" arbor is required.

Advantages

The segmented diamond rim with five segments balances cutting speed and chip removal to maintain drilling progress in dense materials. Its 10 mm cutting depth and 450 mm overall length allow through-holes and deep penetrations while providing sufficient clearance for coolant flow during wet drilling. The 1.1/4" threaded connection ensures compatibility with a wide range of core drilling rigs and adapters. The design supports both wet and dry operation, enabling flexibility on site depending on material and working conditions.

Suitable for

• Drilling cores in reinforced and unreinforced concrete
• Cutting holes in masonry and brickwork
• Creating openings in ceramic and porcelain tiles
• Installing pipes, conduits and anchor points
• Use with core drilling rigs and hand-held drills with 1.1/4" thread

Key specifications

• Diameter: 52 mm
• Cutting depth: 10 mm
• Overall length: 450 mm
• Segment configuration: 5-segment (5T)
• Connection type: 1.1/4" threaded
• Drilling modes: wet and dry compatible
• Intended materials: masonry, concrete, tiles and similar hard materials

How to use

Mount the diamond core bit onto a compatible arbor or directly to the drilling rig using the 1.1/4" threaded connection and ensure the bit is securely tightened. For dry drilling, use intermittent pressure and allow the bit to cool periodically to avoid overheating. For wet drilling, provide a steady flow of water to the cutting area to reduce heat and remove debris. Start drilling at low speed to establish the pilot contact, then increase speed and apply steady, even pressure. Withdraw the bit occasionally to clear accumulated dust and cooling water and to inspect the segment condition.

Usage recommendations

Use appropriate personal protective equipment including eye protection, dust mask or respirator when dry drilling, and hearing protection as needed. Match drill speed and feed pressure to the material hardness: lower speed and moderate pressure for reinforced concrete, higher speed for tiles with light pressure. When dry drilling, perform short drilling intervals to prevent overheating; when wet drilling, ensure continuous water supply and proper water management on site to avoid slip hazards and equipment damage.
