2. Craft & Performance
All serrated hole saws of the Blue Serrated Centering Exposed Grit Dry Drill 5PC Set are manufactured via high-temperature integrated brazing technology, the core production process that ensures long service life and balanced stable dry cutting efficiency of the Blue Serrated Centering Exposed Grit Dry Drill 5PC Set. The serrated exposed diamond grit design on the cutting end creates wide chip removal gaps, automatically expelling high-temperature stone powder generated during dry rotation and effectively preventing grit blockage and local overheating abrasion after hours of non-stop drilling. The blue anti-rust electrostatic coating on thickened 45# steel body isolates dust and corrosive mineral residue, avoiding surface oxidation even under long-term no-water dry construction environments.
The seamless brazed fusion structure firmly locks exposed diamond grit to stop partial grit shedding under high-speed rotation and sustained friction load. The solid thickened steel base resists bending and drilling deviation, producing smooth burr-free round holes and greatly lowering cracking and chipping risk of fragile tile and stone materials. Free bonus auxiliary accessories including centering drill, twist drill, wrench and fixing screws are provided to realize full-process hole machining, greatly boosting the scene applicability of the Blue Serrated Centering Exposed Grit Dry Drill 5PC Set for all kinds of indoor renovation projects.
