## Long description

The Diam Core Drill Bit S3 with a 72 mm cutting diameter and 450 mm overall length is designed for creating precise circular holes in masonry, concrete and similar solid building materials. It features a 1 1/4" connection compatible with drills and core drilling rigs that accept this thread size. The tool is intended for tasks that require a clean, accurate 72 mm opening for pipes, conduits or ventilation penetrations, offering a balance between cutting depth and reach for common installation work.
Advantages
The core bit provides straight, consistent cuts in masonry and concrete due to its engineered cutting crown and flute design. Its 450 mm length gives sufficient reach for through-wall and partial-depth drilling without excessive flex. The standard 1 1/4" connection ensures compatibility with a wide range of rotary drills and core drilling attachments, simplifying tool changes on site. The construction supports repeated use in installation and renovation tasks where a reliable 72 mm diameter hole is required.
Suitable for
Drilling 72 mm openings for plumbing pipes and waste lines
Creating penetrations for electrical conduits and cable entries
HVAC duct and ventilation pass-throughs requiring a 72 mm hole
Renovation and retrofit work in concrete, brick and masonry
Key specifications
Cutting diameter: 72 mm
Total length: 450 mm
Connection type: 1 1/4" threaded connection compatible with corresponding drill arbors
Material compatibility: masonry, concrete and similar solid substrates
Intended use: wet or dry drilling depending on machine and application specifics
How to use
Mount the core drill bit onto a drill or core rig with a compatible 1 1/4" arbor, ensuring the connection is secure. For best results, align the bit perpendicular to the work surface and start at low speed to establish the cutting path, then increase speed and apply steady, even pressure. Use water cooling if the drill setup and substrate permit it to extend tool life and reduce dust. Withdraw the bit periodically to clear debris and prevent clogging of the cutting segments.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, dust mask and hearing protection). Match drill speed and feed pressure to the base material and follow the drill manufacturer's recommendations. For reinforced concrete or heavily abrasive materials, consider using a compatible diamond core bit designed specifically for those conditions.
