## Summary description

Diamond core drill bit with 55 mm cutting diameter by HOGERT, model HT7D290. Designed for drilling precise holes in hard materials such as concrete, masonry and stone. Features diamond cutting edge for efficient cutting and longer life. Suitable for use with compatible rotary and core drilling tools for installation, plumbing and construction tasks.

## Long description

Diamond core drill bit 55 mm HOGERT HT7D290 is a precision cutting tool designed for creating 55 mm diameter holes in hard building materials such as reinforced concrete, natural stone and masonry. The bit features a diamond-segment cutting edge bonded to a steel body to combine wear resistance with stable drilling performance. It is intended for use with compatible rotary and core drilling tools in installation, plumbing and construction tasks where accurate, clean holes are required.
Advantages
The diamond cutting edge provides efficient material removal and a longer service life compared with standard carbide bits. The solid steel body ensures torsional strength and reliable centering during drilling. Its 55 mm cutting diameter yields consistent, circular holes suitable for pipe passages, anchor installation and cable routing. The design reduces the tendency to wander at startup and helps maintain hole geometry in abrasive substrates.
Suitable for
 Drilling through concrete and reinforced concrete
 Creating openings in natural stone and masonry
 Making holes for plumbing pipes, electrical conduits and anchors
 Core drilling tasks with compatible rotary or core drilling machines
Key specifications
 Cutting diameter: 55 mm
 Cutting material: diamond segments
 Body material: steel
 Intended materials: concrete, masonry, natural stone
 Typical use: wet and dry core drilling depending on tool compatibility
How to use
Install the 55 mm diamond core drill bit into a compatible drill or core drilling machine according to the tool manufacturer's instructions, ensuring a secure connection. For most applications, begin drilling at low speed to establish the pilot position, then increase speed and apply steady axial pressure without forcing the bit. When drilling into reinforced concrete or very hard stone, use intermittent withdrawal to remove debris and reduce heat. If the drilling tool and bit support wet drilling, use a controlled water feed to cool the diamond segments and extend tool life. Always follow the drill manufacturer's guidance on speeds, feed rates and clamping.
Usage recommendations
 Use appropriate personal protective equipment including eye protection, hearing protection and dust control measures. Verify tool compatibility and maximum rotational speed before use. For best results, select wet drilling when possible to improve cutting efficiency and prolong diamond segment life; use dry drilling only when the tool and bit are rated for it and with adequate dust extraction.
