Diamond Drill Bit Set 15-Piece tile hole saw kit 🛠️
Description:
This 15-piece diamond drill bit set is built for cutting clean holes in tile, porcelain, soft glass, ceramic and marble, making it suitable for bathroom fittings, kitchen splashbacks and decorative glass work. It aims to deliver precise, chip-free holes with a removable pilot drill and a diamond-coated crown that, according to the manufacturer, improves durability for repetitive drilling tasks.
Key Points
The kit includes multiple sizes of diamond hole saws to cover common hole demands, and each crown features a centre pilot drill with a welded carbide tip for accurate starting points and reduced wander. The crowns use a vacuum-welded diamond coating that resists high temperatures and friction, helping the diamonds adhere to the steel core and prolonging service life. For best performance and longevity, the manufacturer recommends continuous water cooling during cutting to reduce heat and clear debris.
This set is straightforward to use for tradespeople and competent DIYers alike. Fit the pilot into the crown, position the pilot where the hole is needed, then cut at moderate speed while applying water. The result is smoother edges and fewer chips on glazed surfaces. ⚒️💧

Benefits
The vacuum-welded diamond layer provides greater particle adhesion, which means the crowns retain cutting efficiency over more holes compared with non-welded alternatives. This contributes to cleaner, more precise holes with reduced chipping on glossy tiles and delicate materials. The removable pilot drill simplifies replacement and allows the same crown to be re-used even if the pilot becomes worn.
Compact and organised, the set covers a broad size range so there is less need to source individual saws for occasional projects. The welded carbide pilot tip improves centring when starting holes in slippery or curved surfaces, reducing the chance of slipping and accidental damage to workpieces. 😊
Usage Recommendations
Begin with a low to moderate drill speed and steady pressure while ensuring a constant flow of water to the cutting edge. Avoid forcing the crown through material; instead, let the diamond do the work and lift occasionally to refresh the cooling water. Consider that cutting very hard stones like dense granite will wear the crowns faster than porcelain, so expect shorter life in heavy industrial use according to the manufacturer.
