Diamond drill bits are specialised cutting tools designed for drilling clean, precise holes in hard, brittle, and abrasive materials such as glass, porcelain, ceramics, granite, marble, and stone. Instead of cutting with sharpened edges, they use a diamond-coated rim or tip to grind through the surface, reducing the risk of cracks, chips, and breakage.
Available in various diameters and shank types, diamond drill bits are ideal for applications in tiling, glasswork, masonry, and stone fabrication. They can be used wet to minimise dust, control heat, and prolong tool life, or dry for quick, convenient jobs where water cooling is not practical.
Perfect for professional tradespeople and DIY users, diamond drill bits deliver smooth, accurate holes in materials that standard bits cannot handle.
