Core Specs: 4 inch diameter, 15-3/4 inch/400 mm drilling depth, and 1-1/4-7 standard thread; it fits most standard core drill machines and supports heavy-duty tasks. Easy Operation: Supports wet concrete drilling; start at a 15-degree angle, then move to a vertical position and continue drilling; water extends service life, while dry drilling is acceptable for softer construction materials. Efficient Drilling: Made with high-quality diamond grit, it delivers sharp, consistent cutting and longer service life; use with handheld core drills or dedicated core drill rigs for best efficiency. Smart Structure: Precisely engineered sawteeth and a concentric axis design ensure high drilling efficiency while maintaining exceptional durability. Wide Applications: Ideal for concrete, brick, tile, masonry, reinforced concrete, and stone, and widely used for air conditioner, pipe, stair railing installation, and other construction or renovation projects.
