Drill Bit AWTools Diamond Crown 1 1/4 in (32 mm) cutting depth 152 mm overall length 430 mm

AWTools Diamond Crown 1 1/4 in (32 mm) drill bit is a core bit designed for drilling precise holes in masonry, concrete and other hard materials. With a 32 mm diameter, 152 mm cutting depth and 430 mm overall length, this tool is intended for creating core holes for pipes, conduits and anchor installations. The diamond crown tip improves cutting performance and wear resistance compared with standard bits, allowing steady coring in dense materials when used with appropriate drilling equipment.

Advantages

The diamond-segment crown provides efficient material removal and extended life when cutting through concrete and masonry. A 152 mm cutting depth allows the creation of deep cores in a single operation, while the 430 mm overall length gives sufficient reach for through-wall or recessed drilling. The bit is compatible with common core drilling systems and offers consistent hole diameter and clean edges, which reduces the need for post-drilling finishing.

Suitable for

• Drilling core holes for pipe and conduit installation in concrete and masonry
• Creating anchor and sleeve openings in structural elements
• Recessed or through-wall coring where a 32 mm hole is required
• Professional construction and renovation tasks requiring diamond-tipped coring

Key specifications

• Diameter: 1 1/4 in (32 mm)
• Cutting depth: 152 mm
• Overall length: 430 mm
• Tip type: diamond crown segment
• Material compatibility: concrete, masonry and similar hard materials

How to use

Fit the AWTools Diamond Crown core bit to a compatible rotary or core drilling machine following the machine manufacturer's instructions for mounting and securing core bits. Mark the drilling position and, if possible, use a drilling guide or anchor the drill rig to ensure perpendicular alignment. Start at a low speed to establish the cut, apply steady axial pressure and use water cooling if recommended by the drilling equipment to reduce dust and extend bit life. Withdraw periodically to clear debris when coring deep holes.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection, dust mask) and follow recommended safety and cooling procedures. Match drill speed and feed to material hardness and machine specifications to maximize cutting performance and service life of the diamond crown bit.
