Drill bit for concrete RUBI 65 mm cylindrical (model 04920)

RUBI cylindrical drill bit for concrete, 65 mm diameter (model 04920) is designed to create precise cylindrical holes in concrete and similar masonry materials. This 65 mm core/drill bit produces clean bores for installations such as anchors, plumbing sleeves and electrical penetrations when used with compatible rotary or hammer drilling equipment. The bit is intended for professional and DIY applications where an accurate, round opening is required in solid substrates.

Advantages

The drill bit features a robust construction that maintains roundness and cutting performance when drilling into dense materials. Its cutting geometry is optimized for efficient material removal and reduced vibration during operation, contributing to straighter holes and prolonged tool life under normal use. The cylindrical design enables stable mounting and alignment in standard core holders and drill chucks suitable for masonry bits.

Suitable for

• Drilling through concrete walls and floors for anchor installation
• Creating openings for plumbing pipes and sleeves
• Making penetrations for electrical conduits and cable runs
• Core drilling for inspection or sampling in masonry

Key specifications

• Diameter: 65 mm
• Type: cylindrical core/drill bit for concrete and masonry
• Compatibility: suitable for rotary or hammer drilling equipment designed for masonry bits
• Application: wet or dry drilling depending on machine and site conditions—follow equipment guidance

How to use

Select a compatible drilling machine and secure the drill bit according to the machine manufacturer's instructions. Mark the drilling position, ensure stable support for the workpiece or machine, and start at low speed to establish the bore. Apply steady, even pressure and adjust speed and feed according to material hardness and drilling conditions. Clear debris periodically to avoid overheating and binding. When drilling deep holes, withdraw the bit occasionally to remove cuttings and allow cooling.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves, dust mask) and follow the drilling machine manufacturer's recommendations for speeds, mounting, and coolant use. Avoid excessive lateral forces to preserve bit life and ensure the accuracy of the hole.
