## Long description

The Diamond Core Drill Bit Dedra HW4117, 117 mm x 400 mm is a professional diamond-segmented core bit designed for drilling precise circular holes in hard construction materials. With a 117 mm cutting diameter and a 400 mm overall length, this core bit is intended for use with compatible core drilling machines to make clean openings in concrete, masonry and natural stone. The segmented diamond rim improves cutting efficiency and facilitates dust and debris removal during dry or wet drilling, depending on the drill and method used.
Advantages
The Dedra HW4117 combines a diamond-segmented cutting edge with a robust steel body to deliver consistent cutting performance and extended service life on abrasive materials. Its segmented design reduces friction and helps keep the cutting zone cleaner, which supports faster penetration rates and more reliable hole quality. The 400 mm overall length provides sufficient reach for many standard installations while maintaining stability during operation.
Suitable for
Creating circular openings for plumbing and pipework in concrete and masonry
Installing electrical conduits and boxes through walls and floors
Core sampling and creating passages in stone and natural rock
General construction tasks requiring precise round holes in hard substrates
Key specifications
Cutting diameter: 117 mm

How to use
Mount the Dedra HW4117 core bit to a compatible core drilling machine according to the drill manufacturer’s instructions, ensuring correct arbor or thread compatibility. Secure the workpiece or setup, align the drill perpendicular to the intended hole, and start at low speed to seat the bit. Apply steady, even pressure and increase speed as appropriate for the machine and material. Use water cooling if the drill and the job site allow to reduce heat and extend diamond segment life; for dry drilling, monitor the bit temperature and dust. Withdraw the bit periodically to clear debris and check progress until the hole is completed.
Usage recommendations
The Dedra HW4117 performs best when used with a stable core drilling rig or hand-held core drill with suitable mount and adequate power. For reinforced concrete, use slower feed and consider wet drilling to slow wear on the diamond segments. Always wear appropriate personal protective equipment, control dust exposure, and follow the safety guidelines of the drilling machine manufacturer.
