The diamond coating and vacuum brazing process create a sharp cutting edge that stays stable even at high temperatures. This means smoother drilling with less stopping or tool wear, especially when working on dense materials.

Start at a 15–45° angle to reduce resistance, then bring the bit upright as the hole forms. This simple approach gives you better control and cleaner results, even if you're new to drilling tile or stone.

Each kit includes multiple bit sizes plus specialized tools like a finger bit and cone bit, so you can shape, widen, and finish holes without switching tools constantly. From small precision cuts to larger openings up to 2 in (50 mm), you're covered.

Compared to basic hole saws, this set cuts smoother, lasts longer, and produces less mess—especially in wet mode where dust is reduced and durability increases.

Get clean, precise holes every time without the frustration of cracked materials.
