DeWalt Diamond Drill Bit

The DEWALT DW5578, DW5580, DW5582, and DW5584 diamond drill bits are engineered for precision drilling in hard materials such as tile, porcelain, and glass. Each bit features a diamond-welded tip for enhanced durability and longevity. The reverse spiral thread design ensures continuous water feed during drilling, which aids in cooling and extends the bit's life. Additionally, the core ejection slot facilitates easy removal of plugs, making repetitive drilling tasks more efficient.
