## Summary description

Diam S3 core drill bit with a 225/450 mm cutting section and 1 1/4 inch connection. Designed for drilling large-diameter cores, it suits wet or rotary drilling rigs that accept a 1 1/4" thread. Use for extracting concrete, masonry or similar materials where a long cutting length and standard 1 1/4" mounting are required.

## Long description

The Diam S3 core drill bit with a 225/450 mm cutting section and 1 1/4 inch connection is engineered for drilling large-diameter cores in concrete, masonry and similar materials. The extended cutting length provides deeper core extraction in a single pass, while the 1 1/4" threaded connection fits drilling rigs and adaptors that accept this standard mounting. The tool is suitable for use with wet drilling setups to control dust and cool the bit or with rotary drilling where applicable.
Advantages
The long 225/450 mm cutting section reduces the need for multiple passes and speeds up core removal when working on thick elements. A standard 1 1/4" connection ensures compatibility with a broad range of core drilling rigs and adaptors. The bit is intended for wet drilling to maintain cutting efficiency and prolong diamond segment life, and it also performs adequately in rotary drilling applications when recommended by the rig manufacturer.
Suitable for
 Drilling large-diameter cores in reinforced or plain concrete
 Creating openings in masonry and brickwork
 Wet core drilling to control dust and cool the bit
 Rotary drilling rigs that accept a 1 1/4" thread
Key specifications
 Cutting section length: 225/450 mm
 Connection size: 1 1/4 inch threaded mount
 Intended materials: concrete, masonry and similar mineral substrates
 Drilling modes: wet drilling recommended; suitable for compatible rotary rigs
 Application: large-diameter core extraction and deep core drilling
How to use
Mount the core drill bit on a compatible drilling rig or adaptor with a 1 1/4" thread. When drilling concrete or masonry, use a wet drilling setup where possible to supply continuous water flow to the cutting area; this cools the diamond segments and reduces dust. Start drilling at low speed to establish the pilot contact, then increase speed and apply steady, even feed pressure. Periodically retract the bit to remove debris and allow water to reach the cutting face. Follow the rig and bit manufacturer's recommendations for rotation speed and feed rate.
Usage recommendations
Use the Diam S3 core drill bit primarily with wet drilling to maximize segment life and cutting performance. Verify that the drilling rig accepts a 1 1/4" thread and that rotation speed and feed settings match the substrate hardness. For reinforced concrete, monitor cutting progress and clear debris frequently to avoid jamming or overheating.
