Diamond core drill bit LOGO-Tools 42 mm diameter, 450 mm length, model 10.310S

Diamond core drill bit LOGO-Tools 42 mm diameter, 450 mm length, model 10.310S is a single-piece core bit engineered for cutting precise circular holes in concrete, masonry and reinforced concrete. The bit has a 42 mm cutting diameter and a 450 mm overall length, and is intended for use with rotary or rotary‑percussion drilling rigs. Its diamond-segment cutting edge provides efficient material removal and is suitable for wet drilling to extend tool life and reduce dust.

Advantages

The diamond-segment edge delivers consistent cutting performance and improved durability compared with conventional carbide bits. With a 450 mm length the core bit reaches deeper penetration for through‑wall and slab applications while maintaining stability during drilling. Compatibility with wet drilling reduces friction and heat buildup, which helps preserve diamond segments and maintain drilling speed.

Suitable for

• Drilling clean circular holes in concrete and reinforced concrete
• Creating penetrations for plumbing and water pipe installations
• Installing electrical conduits and wiring routes through walls and slabs
• HVAC penetrations for ducts and ventilation components

Key specifications

• Cutting diameter: 42 mm
• Overall length: 450 mm
• Cutting edge: diamond-segment
• Drilling method: suitable for rotary and rotary‑percussion rigs
• Wet drilling compatibility: yes
• Intended materials: concrete, masonry, reinforced concrete

How to use

Install the core bit into a compatible drill chuck or arbour according to the drill manufacturer’s instructions, ensuring secure mounting and correct alignment. For best results, begin drilling at moderate speed with steady feed pressure; if available, use water to cool the cutting edge and remove debris. Withdraw the bit periodically to clear cuttings and inspect the diamond segments for wear. Maintain consistent feed and avoid excessive lateral force to prevent damage to the core bit and the drill.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask when dry drilling. Prefer wet drilling where possible to reduce dust and extend bit life. Match drill speed and feed to the substrate hardness and follow the drilling rig manufacturer’s guidance for optimal performance.
