Laser-Welded Thin-Wall Diamond Core Drill Bit

Rapid Penetration & Clean Core Extraction

St. Bairui Laser-Welded Thin-Wall Core Drill Bit is engineered for high-precision drilling in reinforced concrete, stone, and masonry. The thin-wall crown segment minimizes frictional resistance, accelerating drilling speeds while guaranteeing effortless, jam-free core ejection.

Highlights

• Laser-welded segments eliminate thermal detachment in dry or low-water drilling
• Thin kerf profile increases drilling speed by 40% with reduced motor load
• Standard 1-1/4in-7 UNC thread connection fits all major core drill rigs
• Long working barrel with spiral outer flute for swift dust and slurry clearance
