• Professional-Grade Size & Compatibility: This 3 1/4 inch diamond core drill bit features a 15.7 in (400 mm) drilling depth and 1-1/4″-7 standard thread, compatible with most handheld core drills and core drilling rigs used in construction and renovation.
• High-Density Diamond for Smooth Cutting: Manufactured with premium diamond grit and precision-welded segments, this wet diamond core bit delivers sharp, consistent cutting with reduced vibration and extended service life in hard materials.
• Optimized for Wet Drilling Performance: Designed primarily for wet drilling, this concrete core drill bit runs cooler, cuts cleaner, and lasts longer when water is used. Dry drilling is acceptable for softer masonry materials when water is unavailable.
• Engineered Structure for Accuracy & Stability: The concentric axis design and precisely engineered cutting teeth help maintain straight, stable drilling, improving hole accuracy and efficiency for professional installations.
• Wide Range of Construction Applications: This diamond core drill bit is suitable for reinforced concrete, cured concrete, brick, block, stone, tile, stucco, masonry, and similar materials—ideal for HVAC installations, pipe routing, railing mounts, and renovation projects.
