GRAPHITE Diamond Core Drill Bit 82 mm x 450 mm M22 for 58G540 Drilling Rig

Professional diamond core drill bit engineered for heavy-duty wet drilling in concrete, reinforced concrete, brick, masonry, and stone. The open-ended design allows continuous core ejection, while laser-welded diamond segments deliver exceptional cutting speed and durability in demanding construction environments.

Advantages

Laser-welded industrial diamond segments ensure high resistance to abrasion and impact, extending service life even in reinforced concrete. The open-ended body facilitates efficient core removal, reducing downtime during deep drilling. M22 thread provides secure, tool-free mounting to the GRAPHITE 58G540 core drilling rig, ensuring concentric rotation and precise holes.
